Ask any expat who has just landed in Kuala Lumpur or Ho Chi Minh City what surprised them most about settling in, and a fair number will mention the bank account before the visa stamp. Most retail banks across the region require proof of a long-term visa or residence permit before they will open a current account, which creates an awkward gap for anyone paying an apartment deposit or a school fee in the first week. Landlords in Singapore and Bangkok increasingly insist on a local bank transfer rather than cash or a foreign card, and some employers won't release a first paycheque to an account outside the country at all. You end up needing a local bank to get a visa-adjacent document, and needing that document to open the local bank account.
Digital-first accounts have become the default workaround. Wise, Revolut and Singapore's own Wio Bank all let you open a multi-currency account before you've set foot in the country, using a passport and a proof of address from your home country, and the account works from day one for receiving salary, paying rent by bank transfer, and holding balances in US dollars, euros or the local currency side by side. The catch is that a Wise account doesn't behave like a local bank account for every purpose: some employers still refuse to pay salaries into it, and it typically can't be used to set up recurring GIRO-style utility payments the way a Singaporean DBS or Malaysian Maybank account can.
The credit history you left behind doesn't travel with you
Your credit history stays exactly where you built it.
A decade of on-time mortgage payments in London or Sydney means nothing to a Thai or Vietnamese bank assessing a first credit-card application, because credit bureaus in most Asian markets don't exchange data with Western agencies at all. HSBC Expat and Citigold try to bridge the gap by letting existing customers port a relationship rather than starting from zero, but that service is generally reserved for accounts holding a minimum balance, often USD 100,000 in Citigold's case, which puts it out of reach for most people relocating on a standard local contract. Without that history, expect to be asked for a large security deposit on your first local credit card, sometimes equal to the full credit limit, until roughly a year of local repayment history builds up.
What actually works, country by country
Singapore is the easiest market in the region by a wide margin. DBS, OCBC and UOB will all open an account for an Employment Pass holder within days of the pass being issued, and DBS's multi-currency account handles USD, EUR and SGD balances without the conversion fees that plague a standard current account. Malaysia is close behind: Maybank and CIMB both accept an MM2H long-stay visa or an Employment Pass as sufficient proof, though branch staff outside Kuala Lumpur are noticeably less familiar with the paperwork foreign applicants bring in.
Vietnam and Thailand sit at the harder end. Vietcombank and Sacombank in Vietnam generally require a temporary residence card rather than a tourist or business visa, a document that itself takes weeks to process, and staff at smaller branches frequently ask for documents the head office doesn't actually require. Thailand's Bangkok Bank and Kasikornbank will open accounts for work-permit holders, but foreign nationals without a Thai-registered employer, freelancers and remote workers on non-immigrant visas among them, are often turned away outright, regardless of how much they intend to deposit. For anyone arriving without a job offer already signed, opening a Wise account before the flight is the better move: waiting until you land to sort out money almost always costs more in emergency currency-exchange fees at the airport than the transfer fees would over an entire year.
Sending money home without losing 5 percent to fees
Traditional bank wire transfers remain the most expensive way to move money between Asia and anywhere else, often combining a flat fee of USD 20 to 45 with an exchange-rate margin of 2 to 4 percent that never appears as a separate line on the statement. Wise publishes its margin openly, typically under 1 percent on major currency pairs, which is why it has become the default choice among expats moving salary back to a home-country mortgage or sending remittances to family. Revolut undercuts Wise on some corridors but caps free transfers by tier, and the free allowance resets monthly rather than accumulating, so heavy senders on a Standard plan often hit the ceiling by the third week of the month.
None of this makes traditional banks obsolete, though. A same-day, guaranteed-rate SWIFT transfer through HSBC or Citibank still beats a fintech app when a property purchase or a large lump-sum transfer needs to clear before a specific deadline, since Wise and Revolut transfers can occasionally take two to three business days to settle on less common currency corridors like Vietnamese dong or Indonesian rupiah, and neither offers a same-day guarantee.
FATCA, CRS, and why your bank suddenly wants your tax ID
American expats meet a specific complication that citizens of most other countries don't: FATCA. Any non-US bank with US expat customers is required to report account balances above certain thresholds to the IRS, and plenty of Asian banks have decided it's simply not worth the compliance overhead of serving American clients at all; Vietcombank, for one, is known among expat forums for rejecting or restricting new US-citizen applications. The good news for everyone else is that CRS, the international reporting standard nearly every Asian country except a handful has signed onto, mostly just means your bank asks for a tax-residency self-certification once a year rather than anything more invasive.
The remote-income problem nobody's bank policy addresses
Freelancers and remote employees paid by a foreign company face a separate wrinkle that visa-and-salary bank policies were never built for: how do you prove income to a landlord or bank when the paycheque lands in a Wise account registered to a UK or US company address? Several banks, DBS among them, have started accepting six months of Wise or PayPal statements as an alternative to a local payslip for account upgrades, but the policy varies branch to branch and rarely appears in writing on the bank's own website. Bring printed statements to the appointment rather than relying on a mobile screen: more than one branch officer has asked for a stamped, printed version specifically because a phone screenshot doesn't satisfy the bank's own audit requirements.
Two documents worth bringing that nobody puts on the checklist
A bank reference letter from your home institution, one paragraph confirming how long you've held the account and that it's been in good standing, smooths almost every account-opening conversation in the region, even though almost no bank's published requirements list it. Notarised, translated proof of address costs a small fee at a notary before departure and saves a return trip to the embassy months later when a bank suddenly asks for something the original visa application didn't require. Both documents take under an hour to arrange before a move and solve problems that otherwise take weeks to untangle once you're already juggling a new job and a new apartment.
The account that actually works ends up being a hybrid for most expats: a local bank account for salary and rent, a Wise or Revolut account for anything crossing a border, and, for the first six months at least, a stack of physical bank statements kept for the day some new landlord or car dealership asks for proof of income nobody warned you you'd need again.
