Which cards work where, which don't charge FX fees, how to build credit in a new country, and why your home-country card may stop working when you move abroad.
Credit cards are simultaneously one of the most useful and one of the most frustrating financial tools for expats. Useful because they offer purchase protection, rewards, and 30–55 days of free credit; frustrating because cross-border usage is expensive, building credit in a new country is hard, and the card that worked perfectly at home may stop working when you move. This guide covers everything expats need to know about credit cards across borders: which networks work where, how to avoid foreign-transaction fees, how to build credit in a new country, and how to manage the transition when you relocate.
Credit card acceptance varies by network and by country. Understanding the network landscape is the foundation for choosing the right card for international use.
Visa is the most widely accepted card network globally, with acceptance at over 80 million merchant locations in 200+ countries and territories. In most countries, Visa acceptance exceeds 95% of card-accepting merchants. The exceptions are a few countries (Russia, Iran, North Korea) where Visa is not available due to sanctions, and some markets where domestic networks dominate (Japan's JCB, China's UnionPay). For expats, Visa is the safest default — it will work almost everywhere.
Mastercard has near-universal acceptance in developed markets and most emerging markets, with acceptance at over 80 million merchant locations. In practice, Mastercard and Visa acceptance are indistinguishable in most countries — merchants that accept one almost always accept the other. Mastercard is slightly weaker in some emerging markets (parts of Africa, South Asia) but the gap is small and closing.
Amex has materially lower acceptance than Visa/Mastercard globally — typically 60–80% of card-accepting merchants in developed markets, lower in emerging markets. Amex is widely accepted in the US, UK, Canada, Australia, and Singapore; less accepted in Europe (particularly outside major cities); and rarely accepted in South Asia, Africa, and parts of South-East Asia. The reason is Amex's higher merchant fees (typically 2.5–3.5% vs 1.5–2.5% for Visa/Mastercard), which lead many merchants to refuse Amex.
For expats, the implication is that Amex should be a secondary card, not the primary card. Carry a Visa or Mastercard as backup for the many places Amex is not accepted.
These networks have limited international acceptance. Discover has reasonable acceptance in the US but is rare elsewhere; Diners Club is accepted in some markets but rare in others; JCB is dominant in Japan but rare elsewhere; UnionPay is dominant in China and widely accepted across Asia but less accepted in Europe and North America. For international expat use, none of these should be the primary card.
Most credit cards charge a foreign transaction fee — typically 2.5–3% — on purchases made in a currency other than the card's home currency. This fee is invisible to most consumers because it is bundled into the exchange rate rather than listed as a separate line item. On a USD 5,000 international purchase, a 3% FX fee costs USD 150 — a meaningful amount that is entirely avoidable.
The solution is a no-foreign-transaction-fee card. Most major issuers now offer at least one no-FX-fee variant, and several premium cards have no FX fees as standard. The best-known no-FX-fee cards include:
For expats, the choice depends on country of residence and credit history. US-connected expats have the deepest pool of no-FX-fee cards; expats in other countries have fewer options but at least one no-FX-fee card is typically available in each major market.
This is one of the most common sources of confusion for new expats. The card you used at home does not necessarily continue to work the same way when you move abroad. Three things can happen:
Most credit cards continue to work for international purchases when you move abroad, as long as the issuer does not detect the move. The card will charge foreign transaction fees (if applicable) and may flag international purchases for fraud review, but the card itself remains usable. The risk is that the issuer may eventually close the account if they detect that you are no longer resident in the country of issuance — most cardholder agreements require you to be a resident.
Card issuers periodically verify cardholder information. If the issuer detects that you have moved (for example, because you stopped using your home-country address for billing), they may require you to update your billing address to your new country of residence. If your new country is not supported by the issuer, the card may be closed.
Some issuers proactively close accounts when they detect that the cardholder has moved abroad. This is most common with credit unions and smaller issuers, but it can happen with major issuers as well. The closure typically happens without warning and can leave the cardholder without access to credit.
The mitigation: maintain a billing address in your home country (a family member's address, a mail forwarding service) for as long as you want to keep the card. Update the card's billing address to this home-country address and use the card for occasional purchases to keep it active. Do not inform the issuer of your move unless you have to.
Credit history is jurisdiction-specific — your excellent credit in your home country does not transfer to your new country. This is one of the most frustrating aspects of moving abroad, particularly for expats moving to the US, UK, or Canada where credit scores are essential for housing, utilities, and employment.
The standard catch-22 of credit building applies in every country: you need credit to build credit, but you need credit history to get credit. Expats face a particularly difficult version because they have no local credit history, no local employment history, and often no local bank account when they arrive.
1. Secured credit card. A secured card requires a refundable deposit (typically USD 200–500) equal to the credit limit. Use the card for small purchases and pay it off in full each month. After 6–12 months of good behaviour, most issuers will convert the secured card to an unsecured card and refund the deposit. This is the standard entry point for credit building in most countries.
2. Credit-builder loan. Some banks and credit unions offer credit-builder loans, where you make monthly payments into a savings account and receive the proceeds at the end of the loan term. The payments are reported to credit bureaus, building credit history. The cost is the interest on the loan, which is typically low.
3. Authorised user on someone else's card. If you have a family member or close friend in the destination country with good credit, ask to be added as an authorised user on one of their cards. The card's history will appear on your credit report, jump-starting your credit building. The risk is to the primary cardholder — they remain liable for your charges.
4. International credit card transfer. Some issuers offer programmes that allow existing customers to transfer their credit history to a new country. American Express Global Card Transfer is the best-known example — if you have an Amex in your home country, you can apply for an Amex in your new country using your existing Amex history, bypassing the local credit check. This is available in 40+ countries and is the single most useful credit-building tool for Amex-holding expats.
5. Alternative credit reporting. Some countries (particularly the US) now have alternative credit reporting services that consider rent payments, utility payments, and streaming subscriptions in addition to traditional credit. Experian Boost and similar services can help build credit without a traditional credit card.
Building credit from scratch in a new country typically takes 12–24 months to reach a score that qualifies for unsecured credit cards and reasonable loan terms. The first 6 months are the hardest — you have access only to secured cards or no cards at all. By 12 months, you should qualify for entry-level unsecured cards. By 24 months, with consistent good behaviour, you should have access to most credit products.
Credit card rewards are a USD 50+ billion industry and the subject of intense consumer attention. For expats, the rewards calculus is more complex than for domestic consumers because the optimal card depends on travel patterns, country of residence, and currency exposure.
Travel rewards (airline miles, hotel points) typically offer higher headline value than cashback but require redemption flexibility and have devaluation risk. Cashback is simpler and more flexible but typically caps at 1–2% of spend. For expats who travel frequently for work or family, travel rewards can be valuable; for expats who do not travel much, cashback is usually the better choice.
For expats, a significant portion of card spend is in foreign currencies. Cards that earn rewards on foreign spend at the same rate as domestic spend are valuable — some cards reduce rewards earning on foreign spend, effectively negating the benefit of the no-FX-fee feature. Read the terms carefully.
Premium cards with annual fees (USD 95–695) offer enhanced rewards and perks but only make sense if you will use the perks. The maths: a card with a USD 395 annual fee needs to deliver USD 395+ of value per year through rewards and perks. For most expats, mid-tier cards (USD 95 annual fee) are the sweet spot — meaningful rewards without prohibitive cost.
The distinction between debit and credit cards matters more abroad than at home. Three considerations:
Protections: Credit cards typically offer stronger purchase protection and dispute resolution than debit cards. Under US Regulation Z, credit card users have zero liability for unauthorised charges above USD 50; debit card protections under Regulation E are weaker, particularly if the unauthorised transaction is not reported promptly. Use credit cards for major purchases and online transactions; use debit cards for cash withdrawals.
ATM withdrawals: Credit card cash withdrawals (cash advances) typically incur a fee (3–5% of the amount) and start accruing interest immediately, with no grace period. Debit card ATM withdrawals are typically free or low-cost, particularly if you use an in-network ATM. For cash abroad, use a debit card (preferably one with no ATM fees and no FX fees, like the Wise card or Schwab debit card for US-connected expats).
Acceptance: Some merchants (particularly for car rentals and hotel deposits) require a credit card, not a debit card. Always carry at least one credit card for these situations, even if you use debit for most spending.
For most expats, the optimal card stack is three cards:
For expats with US ties, the stack might be: Chase Sapphire Reserve (primary, no FX fee, strong travel rewards), Capital One Venture (backup, no FX fee, Visa network), and Schwab debit (no ATM fees, no FX fees). For expats with UK ties, the stack might be: Barclaycard Rewards (primary, no FX fee), Halifax Clarity (backup, no FX fee), and Wise card (ATMs). The specific cards vary by country but the structure — primary, backup, debit — is universal.
Credit cards are a powerful tool for expats but require deliberate management across multiple jurisdictions. The foundations: carry a no-FX-fee Visa or Mastercard as your primary card; maintain a backup card from a different issuer; use a no-fee debit card for ATM withdrawals; maintain a home-country billing address for as long as you want to keep your home-country cards; and start building local credit immediately on arrival using a secured card or Amex Global Transfer if available.
