Sending part-time job income home as an international student

TABLE OF CONTENT

SHARE THIS POST

Studying abroad has numerous perks, including the opportunity to work part-time jobs and earn some money. Sometimes, this income is more than enough to cover your living expenses, but also to send some home. International students with part-time jobs often send remittances to help their siblings and support their parents.

Unfortunately, managing international transactions can be challenging with delayed payments, unfavourable exchange rates, and expensive fees. This article explores how international students can effectively send their earnings back home.

Challenges with sending income home

International transactions are not always straightforward. Students often face hurdles such as:

  • High transfer fees: Traditional banks and other payment solutions often charge high fees for international transfers, which can significantly reduce the amount you can afford to send.
  • Unfavourable exchange rates: Hidden mark-ups on exchange rates can eat into how much your family receives.
  • Delayed payment processing: Depending on the method used, it can take several days for funds to arrive, which can be a challenge in urgent situations. Imagine sending money home for a medical emergency, only to wait a week for it to arrive.
  • Lengthy paperwork: Some platforms require extensive paperwork or proof of income that can be cumbersome for students juggling studies and work.
  • Limited access: Some countries and banks have restrictions on global bank accounts or advanced financial tools.

How to send part-time job income home as an international student

International students have several ways to send money home, each with its own advantages and disadvantages. Here’s a breakdown to help you choose the best option for your needs.

When selecting a payment solution, consider factors such as payment speed, cost, and convenience. Here are some options to choose from:

Traditional banks

International students can use international banks in their host countries to send money home. They are secure and great for sending large sums of money. However, there are some downsides like:

  • Payment delays
  • High transaction fees
  • Markups on exchange rates

Money transfer operators

Payment services Western Union and MoneyGram offer cash pickups at designated stations throughout your home country. Where available, it is a great option for families that don’t have a bank account. Transactions are relatively faster compared to traditional banks, but the exchange rates can be cutthroat.

Digital payment platform

Fintech solutions are revolutionising international transfers by providing multicurrency accounts. International students can send money at low fees, with better exchange rates, and faster transactions, completed within minutes or a few hours. Many of these platforms support direct payments into your family’s local bank account with intermediaries.

How to budget in foreign currencies using the Grey card

•

•

2 min read

Budgeting used to be simple. You earned money, spent money, and tracked what was left. At that time, you had only one account with one currency, which required just one mental model.

Then remote work happened.

Now you might earn in EUR, pay for tools in USD, and travel in between. Discipline isn’t enough for budgeting anymore; you need structure. Without the right structure, even the most careful spender can lose track of where their money is going.

The Grey card comes in as a practical budgeting tool for people who live and spend across borders. I’ll explain.

Why budgeting in multiple currencies breaks down so easily

Most people don’t overspend because they’re irresponsible. Rather, they overspend because their money isn’t organised in a way that reflects how they live.

Here’s what usually goes wrong.

You’re spending across platforms, clients, and countries, but everything is tied to one card. Subscriptions, ads, one-off purchases, and travel expenses all blur together. When something goes wrong, such as a spike in ad spend or an unexpected renewal, it’s challenging to pinpoint the cause quickly.

Add foreign currencies to the mix, and it gets worse. The charges don’t always settle immediately, and these small amounts seem harmless until they quietly add up.

At that point, your budget is broken.

Also read: How to use your Grey card to manage all your subscriptions

What should budgeting look like when you earn and spend globally?

Clarity, separation, and control are the most crucial factors when budgeting across multiple currencies. You should be able to:

  • See exactly what each type of spending is costing you.
  • Stop or pause spending instantly when needed.
  • Protect one part of your budget from another.
  • Make changes without disrupting everything else.

The Grey card is designed around solving these exact needs.

How does the Grey card help with budgeting?

Use multiple cards to separate your spending

One of the most effective budgeting habits is separation. Instead of using a single card for everything, you can create multiple cards with clear purposes.

For example, you can create:

  • One card for subscriptions and recurring tools
  • One card for ads and growth experiments
  • One card for travel or everyday spending
  • One card per client or project

Each card acts like its own budget lane. You don’t need to guess where the money went; you already know.

This is especially useful if you freelance, manage ads, or run multiple income streams. When spending is separated, budgeting becomes more straightforward.

Freeze cards instantly when spending goes off-track

Budgets fail when you can’t act fast enough.

With the Grey card, you can instantly freeze or unfreeze any card in the app. If an ad campaign starts burning cash, freeze the card. If a subscription you forgot about renews unexpectedly, freeze the card. If you’re travelling and want to lock down non-essential spending, freeze the card.

Freezing a card doesn’t affect your other cards or balances. It simply stops that specific spending lane, which is precisely how budgeting should work.

Set limits that protect your budget

Budgets can fail when they’re too rigid. Grey’s spending limits work more like guardrails.

You can set daily or monthly limits per card, receive alerts when you’re approaching your limit, and still stay flexible. The goal isn’t to punish spending. I mean, who wants that? It’s to keep you aware before things drift too far.

For shared cards or subscriptions, limits are especially useful. You know exactly how much can be spent, and nothing sneaks past unnoticed.

Track spending clearly in one place

When you’re budgeting across currencies, visibility matters more than perfection. Every Grey card transaction appears clearly in your app, linked to the card you used. That means you’re not just seeing how much you spent, but why you spent it.

When budgeting time comes around, you’re no longer reconstructing your month from memory. The structure is already there.

Spend confidently across borders

Trust helps with budgeting too. When you’re shopping internationally, paying for ads, or travelling, declined payments and unexpected charges can throw everything off. The Grey Card works across global merchants and even supports Apple Pay and Google Pay, so everyday spending feels normal, even when you’re far from home.

A quick note on protection when spending abroad

An often-overlooked aspect of budgeting is preparing for contingencies in case things go wrong.

When you pay with your Grey card, you have access to Visa benefits, including purchase protection, extended warranties, and price protection, depending on the transaction and your activation status. It’s not something you think about daily, but it adds a layer of reassurance when you’re buying electronics, booking travel, or shopping internationally.

It’s one less thing to worry about while managing money across borders.

What budgeting in foreign currencies is like with the Grey card

When your card and your accounts are aligned, budgeting stops being guesswork. You know what you’re spending, which currency it’s coming from and more importantly, when something changes.

Instead of constantly reacting to your balance, you’re now making decisions with clarity. And that’s what good budgeting should be like, whether you’re at home, travelling, or working remotely.

If you’re ready to make your budget work wherever you are, create or update your Grey card and start spending and budgeting in the ways that matter to you.

Best banking options for people paid in USD but living abroad

•

•

2 min read

The fantasy of being paid in USD while living in another country soon turns into a nightmare for many people when they realise that using their regular banking options is not efficient in managing international payments. Freelancers, expats, and business owners often struggle with high fees, forced conversions to local currencies at unfair exchange rates, and delayed payment processing.

With work structure evolving, more remote workers landing gigs with international clients, and local businesses becoming global, the payment world has also been evolving to meet these modern needs. If you manage a USD income, here are the best banking options for people living abroad.

Direct transfer to a traditional bank using SWIFT

International wire transfers remain a reliable way to send money. While this might not be a top option for freelancers managing routine payments, it works well for businesses managing large sums of money and requiring a more official payment option. Traditional banks are quite reliable, but the high fees, exchange rate markups, delayed payments, and paperwork requirements can be frustrating. Also, your USD income is converted to your local currency without your input.

Grey

Grey offers multi-currency account details, including that USD accounts work like a traditional US bank account. This means you can receive USD payments without having to convert them immediately. You can keep your earnings in USD, convert when it suits you, and withdraw to your local bank at competitive rates.

Grey is specifically tailored for freelancers and remote workers to protect their foreign income and receive their income without breaking a sweat. Grey also integrates seamlessly with freelance platforms and offers more flexibility with its virtual cards for online payments and subscriptions. For many globally paid professionals, this flexibility, speed, and cost efficiency make Grey a top option.

LDMAG1

PayPal

PayPal is one of the most popular cross-border payment solutions, and many international clients choose it for its convenience and trust. For people living abroad, PayPal makes it relatively easy to receive USD payments without needing a foreign bank account.

However, ease of use comes at a cost. PayPal charges relatively high transaction fees, and its exchange rates usually include hidden mark-ups. In many countries, you are required to convert USD to your local currency before withdrawing, which removes flexibility. Account limitations, sudden holds, and compliance reviews are also common complaints among users who rely on PayPal as their primary income channel. As a result, PayPal works best as a backup option or for occasional payments rather than long-term income management.

Wise

Wise has become a popular alternative to traditional banking for people earning in foreign currencies. It provides multi-currency accounts that allow you to receive, hold, and convert USD at mid-market exchange rates with transparent fees.

For remote workers and expats, Wise offers USD account details that clients can pay into as if they were making a local transfer. You can then choose when to convert your funds or spend directly in supported currencies. While Wise is excellent for low-cost conversions and everyday international banking, it may not support all countries equally, and some users prefer more specialised tools for freelancing or platform payouts.

Payoneer

Payoneer is widely used by freelancers, consultants, and online sellers who work with global marketplaces. It provides USD receiving accounts that can be shared with clients or connected directly to platforms such as Upwork and Fiverr.

This option works well if you earn through established freelance platforms or marketplaces that already integrate with Payoneer. However, fees can add up depending on how you receive and withdraw funds, and exchange rates may not always be the most competitive. Payoneer is reliable, but many users see it as functional rather than flexible.

Choosing the right banking option for USD payments

The best banking option depends on how often you get paid, how much control you want over currency conversion, and how sensitive you are to fees. Traditional banks still serve a role for formal or high-value transactions, but they are rarely optimised for modern remote work. Platforms like PayPal offer convenience and are popular, but they are also expensive. Multi-currency and global payment platforms provide the flexibility that international earners increasingly need.

For most people living abroad and earning in USD, Grey lets you receive, keep, and manage USD before converting to local currency at favourable rates. This way, you are in charge of your finances, reduce losses, improve cash flow, and simplify your international transactions.

Can foreigners open a UK bank account without proof of address?

•

•

2 min read

If you’re planning to move to the UK, study there, or work remotely for UK clients, you almost certainly will need a UK bank account. For most people, they’ll quickly contact a few UK banks to open an account, and almost immediately, they hit the same wall: “Do you have proof of UK address?”

Most people don’t.

This could be because you’re not living in the UK yet, or you’re based abroad but need UK banking access. After explaining this, the conversation usually ends there. The bank says they can’t help without proof of address. You’ve failed before you’ve even started. Okay, maybe saying you’ve failed is a bit of an exaggeration, but you get my point.

So, can foreigners open a UK bank account without proof of address? Yes, but only if you know what to do.

Let's explain why UK banks require proof of address, your realistic options, and how to navigate UK banking as a foreigner without the usual documentation.

Why do UK banks ask for proof of address?

UK banks aren’t asking for proof of address to be difficult. I know, I know it can be a bit annoying. They’re in fact required by law to verify customer identities and addresses as part of KYC (Know Your Customer) and AML (Anti-Money Laundering) regulations.

These regulations exist to prevent financial crime, especially across borders. Banks must confirm you are who you say you are and that you have a verifiable connection to the address you’ve provided. This helps prevent fraud, money laundering, and identity theft.

For people already living in the UK, this is straightforward. You can provide a utility bill, council tax statement, or rental agreement showing your name and UK address. For foreigners who don’t live in the UK yet, or who live abroad permanently but need UK banking, these requirements pose a barrier.

LDMAG1

Can foreigners open a UK bank account without proof of address?

Technically, yes, but it depends entirely on which type of account you’re trying to open and with whom.

Traditional high-street banks almost always require proof of address in the UK. Their systems and compliance processes are built around this expectation. Applying to these banks without a UK address usually results in automatic rejection.

Some traditional banks offer international or expat banking services for high-net-worth individuals or specific professional categories (students, employees of multinational companies). These accounts sometimes accept foreign proof of address, but they often come with high minimum balance requirements, monthly fees, or qualifying restrictions.

Digital banks and fintech companies operate differently. Many were built specifically to serve people who don’t meet traditional banking criteria, including foreigners without UK addresses. These companies use technology to verify identity without always requiring physical UK residency.

Digital banks and fintech alternatives

Digital banks and fintech companies built their businesses around serving people that traditional banks aren't capable of serving.

These services typically verify your identity using your passport or national ID card, along with proof of address from your home country. They don’t require you to live in the UK. Once verified, you receive UK banking details that function as traditional UK bank accounts for receiving and sending payments.

However, they don’t offer full high-street bank services like mortgages, loans, or overdrafts (though some are expanding into these areas) and physical branch access (because they’re fully digital)

For foreigners who need UK banking access but do not live in Britain, these alternatives are often the only realistic options.

How does Grey help you open UK accounts?

If you live and work outside the UK but earn money from UK clients, or run a business that needs UK banking, or simply need UK account details without moving to the UK, Grey provides a practical solution.

You don’t need UK proof of address to open a Grey account. Verification is done using your existing identity documents and proof of address from where you currently live. Once verified, you receive UK banking details (sort code and account number) that your clients, employers, or customers can pay into as if you had a traditional UK bank account.

Grey also offers GBP, EUR, and USD accounts, meaning you can receive payments in multiple currencies without forced conversion. You control when to convert money and at what rates. For freelancers, remote workers, and businesses operating internationally, this flexibility matters.

Grey isn’t trying to replace your local bank. It’s a layer that sits alongside your existing banking, giving you access to UK (and other) banking infrastructure without needing to physically live in those countries.

Also read: How Grey differs from a UK bank

Can foreigners open a UK bank account without proof of address?

If you need UK banking to receive payments, hold pounds, and manage money digitally, fintech alternatives work well.

Grey gives you GBP, EUR, and USD accounts with UK banking details, no UK address required. Verify your identity using documents from your home country, receive your UK sort code and account number, and start enjoying truly inclusive global banking

How to budget in foreign currencies using the Grey card

2 min read

Budgeting used to be simple. You earned money, spent money, and tracked what was left. At that time, you had only one account with one currency, which required just one mental model.

Then remote work happened.

Now you might earn in EUR, pay for tools in USD, and travel in between. Discipline isn’t enough for budgeting anymore; you also need structure because, without proper structure, even the most careful spender can lose track of where their money is going.

Your Grey card is a practical budgeting tool for people who live, work, earn, and spend across borders. I’ll explain.

Why budgeting in multiple currencies breaks down so easily

Many people who overspend don't do so because they’re irresponsible. But because their money isn’t organised in a way that reflects how they live.

It’s pretty common to be juggling subscriptions in USD, running ads in EUR, buying coffee in GBP, and somehow all on the same card. Eventually, everything blurs together. You can no longer track your Netflix renewal, that Facebook ad campaign, the flight you booked last week, or the coworking space membership. Then one day you check your balance and think, “Where did all that money go?” You know you spent it. You just can’t figure out where, or why, it felt like so much more than you expected.

It’s not that you’re careless. It’s that your money isn’t organised in a way that matches how you actually live and work. And once things start blurring, it’s nearly impossible to untangle without spending an hour combing through statements, converting currencies in your head, and still not feeling certain you’ve caught everything.

At that point, your budget is broken.

How to shop in the US or Europe with your Grey card

•

•

2 min read

A few months ago, I was eyeing a pair of sneakers on a US website for weeks. Then the store started running sales and I decided to buy them (hashtag #YOLO), but my bank card declined the payment.

Not once, not twice… but four times!.

The same card that worked perfectly in Nigeria where I live, and the same details I’d used for years. I tried to get another card, but by then, sales had ended, and the sneakers were out of stock. It was annoying, but I just had to accept my L.

If you’ve ever tried to shop internationally, on sites like ASOS UK, Amazon US, Zara EU, or even the Apple Store, you may already be familiar with this pain. Sometimes the website rejects your card. Sometimes your bank blocks the transaction. Sometimes the currency conversion takes too long, and the payment times out.

It shouldn’t be this difficult to buy something online in big 2026… yet for many people, it still is.

But if you use a Grey card, you'll eliminate the uncertainty of thoughts like, “Will this payment go through?”, and transform your international shopping into a simple and predictable process.

Why shopping abroad is often frustrating

Shopping from US or European stores usually comes with these hurdles:

1. Many foreign merchants decline local cards

Some US/UK online stores automatically reject certain African-issued cards, even if you have more than enough balance.

2. Stores bill strictly in USD, GBP, or EUR

If your card requires manual currency conversion, it can cause payment delays that may result in declines.

3. Banks block “suspicious” international transactions

This usually happens when the merchant is unfamiliar.

4. Conversion errors and hidden fees

Some cards convert long after the purchase, leading to surprises on your statement.

These problems are common, but they’re also exactly what Grey card is built to avoid.

How your Grey card makes shopping internationally easy

Smart spending across multiple currencies and USDC

Your Grey card doesn’t require you to pick or switch wallets before paying. Instead, it automatically spends from your balances. Your USD account is debited first; if that’s empty, your USDC, and then the highest of your remaining balances.

This means your payment goes through as long as you have funds available in your account, without requiring you to consider currencies at checkout.

Works across major US and European stores

Your Grey card is an international spend card, so you can pay at 150 million merchants worldwide.

Use Apple Pay and Google Pay

For stores that support mobile wallets, you can simply add your Grey Visa card to Apple Pay or Google Pay. This is more secure and makes for much faster checkouts.

Create multiple cards for better organisation

If you shop frequently or mix personal and business purchases, you can:

  • Use one card for personal shopping
  • another for business imports
  • another for gift purchases

It keeps your spending clean and easy to track.

Freeze and unfreeze anytime

You can always freeze your cards to control your spending.

Better protection for online transactions

You receive real-time notifications, card controls, and instant limits - everything you need for peace of mind when buying from foreign sites.

LDMAG1

How to shop in the US or Europe with your Grey card

1. Request your Grey visa card

Create a Grey account and go to the cards section of your Grey app to request a Grey card for $5.

2. Add your card to the store’s checkout

Enter your card details or simply pay through Apple Pay/Google Pay.

3. Make your purchase normally

Shipping, duties, and taxes will be displayed as they are for every other international shopper.

4. Track everything in your Grey app

Every charge, refund, or verification appears instantly, so there are no surprises later.

Tips for smarter international shopping

  • Use a separate card for business or bulk purchases so you can easily track expenses.
  • Keep a bit extra in your wallet for shipping fees and taxes.
  • Use Apple Pay/Google Pay when available. It’s the most seamless way to tap and pay, and also supports contactless payments.

Shopping abroad doesn’t have to be stressful

Your Grey card helps you shop with confidence. There are no random declines or conversion drama. Ahead of your next international purchase, you can create your Grey card and enjoy a smoother, more predictable shopping experience.

How to pay online and in stores worldwide with your phone

•

•

2 min read

I was halfway through buying coffee in Lisbon when I patted my pockets looking for my wallet and realised I’d left it in my hotel room. I wasn’t moved in the slightest. A worthy, some would even argue, better alternative — my phone — was already hovering over the card reader to complete the payment.

That was a moment of realisation of how much things had changed. A few years ago, travelling required carrying multiple cards, worrying about foreign transaction fees, and hoping the ATM wouldn’t “swallow” my card in some random city. Now I pay for nearly everything with my phone. Subscriptions, flights, groceries in foreign countries, late-night takeaway orders, anything in fact.

How does it work?

How paying with your phone actually works

When I first started using mobile payments, I assumed my phone was doing something complicated and vaguely magical. In a way, I was right.

Your phone can store your card details securely in a digital wallet. Apple Pay if you’re on iPhone, Google Pay on Android, or other regional options, depending on where you are. When you pay, your phone communicates with the payment terminal via NFC (Near Field Communication), the same technology that powers contactless cards.

You authenticate the payment using Face ID, fingerprint, or a passcode, and the transaction goes through. The money comes out of whichever card or account is linked to that digital wallet. From the merchant’s perspective, it looks like a normal card payment. From your perspective, it’s faster and more convenient than fumbling for a physical card.

Online payments work similarly. When checking out, you can use Apple Pay or Google Pay instead of typing in card details. Your phone authenticates using biometrics, and the payment processes are instant. No manually entering sixteen-digit card numbers, expiry dates, or security codes.

The convenience is brilliant. But convenience doesn’t mean cost-free.

Paying online from anywhere in the world

I spend a lot of money online, honestly, probably more than I should, and most of it involves foreign currencies. Subscriptions to US software services. European design tools. UK-based platforms. Occasionally, buying something from an online shop halfway across the world because it’s not available locally.

For years, I paid for everything with a local bank card and didn’t think twice about it. Every transaction went through, so I assumed it was working fine. Then I started looking at my statements more carefully and realised how much I was losing.

When you pay for something online in a foreign currency using a regular bank card, three things usually happen. Your bank converts the currency at its exchange rate, which is almost always 2 - 4% worse than the real mid-market rate. They might charge a foreign transaction fee, sometimes 2 - 3% of the purchase. And if the merchant offers to convert the currency for you at checkout (something called dynamic currency conversion), that’s usually even worse.

On a $100 subscription, you might lose $5 - $7 just to fees and poor conversion rates. Multiply that across every international payment you make in a year, and it adds up fast. I calculated mine once, it was over $600 annually. Six hundred quid, gone, for no reason other than using the wrong card.

Paying in physical stores globally

Paying with your phone in physical stores works the same way contactless cards do, just more conveniently. You tap your phone on the terminal, authenticate, and the payment goes through. It’s particularly useful when travelling because you don't have to worry about carrying the right physical cards or whether a shop accepts your card network.

I’ve paid for coffee in Berlin, groceries in Dubai, transport in Tokyo and dinners in Cape Town, all with my phone. It’s seamless, and merchants barely look up because contactless payments are standard nearly everywhere now.

But again, the ease of payment doesn’t mean you’re paying efficiently. Every time I tapped my phone abroad using my regular bank card, I was getting hit with foreign transaction fees and terrible exchange rates. The transaction felt instant and painless, but my bank was quietly taking 4 - 5% every time.

The worst part is you don't see it happening. The payment just says "approved." You don't get a breakdown of fees or exchange rate markups. You only notice when you check your statement later and realise that €50 dinner somehow cost you £47 instead of £43.

Why your card setup matters

If you link a regular bank card with high foreign transaction fees and poor exchange rates, your mobile payments will still cost you money. The phone is just the interface. The financial infrastructure behind it, meaning the card, the account and the currency handling, is what actually matters.

I realised this after a trip to France. I’d paid for everything with my phone, felt very modern and efficient, then checked my statement and saw I’d lost nearly £80 to conversion fees and markups over one week. My phone wasn’t the problem. My card was.

That’s when I started looking for a better setup, something designed for people who regularly spend money internationally and don’t want to lose a percentage of every transaction to avoidable fees.

How Grey makes global phone payments easier

Apple Pay and Google Pay are brilliant. They make payments faster and more secure. But they don’t solve the underlying problem of whether you’re paying efficiently or expensively.

Grey changed how I think about paying with my phone because it solved the card problem, not just the payment method.

When you open a Grey account, you get USD, GBP and EUR multi-currency accounts.

The Grey card connects directly to these accounts.

What really impressed me was the control. Grey lets you create multiple cards. I've got one for subscriptions, one for travel, and one for general spending. If a card is compromised or I'm worried about a particular merchant, I can instantly freeze it in the app and create a new one in seconds. I can set spending limits, track exactly where my money is going, and budget more intelligently by separating spending categories across different cards.

For someone who earns in multiple currencies or regularly spends internationally, this setup makes a material difference. I’m not losing money every time I tap my phone. I’m spending efficiently, with full visibility and control.

The right card changes everything

I love paying with my phone. It’s faster, more secure, and more convenient than carrying a wallet full of cards.

But payments are only as good as the card linked to them. If you’re paying with your phone but using a card with high fees and poor exchange rates, you’re still losing money on every transaction. The tap is convenient, but the cost is hidden.

The right card makes mobile payments genuinely efficient, not just convenient. That’s the difference between losing hundreds annually to avoidable fees and keeping the money you earn.

Get it right by opening a free Grey account today and getting the card that works globally and transparently.
