Thai Bank Account and Financial Evidence for a Marriage Visa

Why Bank Evidence Matters

Certain spouse-based immigration routes require financial evidence. Depending on current rules and the application route, this may involve funds in a Thai bank account, qualifying income, or another accepted method. The deciding office determines what is acceptable. The two most commonly cited routes are a Thai bank deposit of 400,000 THB, or documented monthly income of around 40,000 THB — with a proportional combination of both sometimes accepted (for example, 200,000 THB in savings plus 20,000 THB in monthly income). Which route suits you best often depends on whether your income is easier to document than moving a lump sum into a Thai account, or vice versa.

Exact amounts, seasoning periods, and document formats can change. Never transfer money based solely on an old article or social-media post.

Opening and Maintaining the Account

Bank account opening requirements vary by bank, branch, nationality, visa status, and compliance checks. Ask the intended branch what passport, address, immigration, tax, or supporting documents it requires. The account name should match the passport exactly. Most banks want to see a valid visa (not simply a visa-exemption stamp), proof of address, and sometimes a letter from your embassy or employer — requirements genuinely vary by branch, so it’s worth calling ahead or visiting in person to confirm before assuming a specific document list applies everywhere.

Keep the account active and avoid unexplained movements that make the evidence difficult to understand. Preserve transfer receipts and source-of-funds documents.

Seasoning and Balance Timing

Some applications require funds to remain in the account for a specified period before filing. Confirm the current period and whether the balance must remain after filing or during consideration. Calendar the earliest safe application date. A commonly cited seasoning period is two months before a first application and three months before each annual renewal — moving funds in and then back out, even briefly, during this window can reset the clock entirely, which is one of the more frustrating and avoidable delays applicants run into.

Bank Letters, Statements and Passbooks

Immigration may request a bank letter, statements, passbook copies, and an update made close to the filing date. The acceptable issue date and format can vary. Ask both the immigration office and bank what can be produced and when. Bank letters are often expected to be dated very close to your actual filing appointment, sometimes within just a few days, so this is usually the last document you obtain rather than something to arrange weeks in advance — plan your other preparation around this constraint rather than the other way around.

Check that account number, holder name, balances, and transaction history are consistent across every document.

Income-Based Evidence

Applicants relying on income should verify the currently accepted evidence with the responsible authority. Rules concerning embassy income affidavits, pension letters, transfers, tax records, and bank history are not uniform for all nationalities or offices. A number of embassies, including several major ones, no longer issue the income-verification letter that many Thai immigration offices historically accepted — where this is the case, twelve months of documented qualifying deposits into a Thai account is often the practical alternative, which is worth knowing well before you assume the embassy-letter route will be available to you.

Choosing Between the Two Routes

The bank deposit route suits people with accessible savings who prefer a one-time seasoning period over ongoing income documentation. The income route suits people with stable, well-documented earnings who’d rather not tie up a large lump sum in a Thai account. Neither is inherently easier — the right choice depends on your specific financial situation and which type of evidence you can document more cleanly.

Common Financial-Evidence Mistakes

Frequent problems include opening the wrong account type, using a joint account when an individual account is expected, dropping below a required balance, obtaining a letter too early, failing to update the passbook, and being unable to explain a large last-minute transfer.

Frequently Asked Questions

What balance is required?

Confirm the current amount with the deciding immigration office because rules can change.

Can I use a joint account?

Do not assume so; verify the accepted account ownership format.

How recent must the bank letter be?

Local requirements vary, so ask shortly before filing — many offices expect it dated within just a few days of your appointment.

What happens if the balance drops below the threshold during seasoning?

This can reset the seasoning period, since the office is generally looking for funds genuinely held over the full window, not just present on the day of filing.

Can I use the income route if my embassy doesn't issue income letters?

Often yes, using twelve months of documented qualifying deposits into a Thai account as an alternative — confirm this with your specific immigration office.

Official Verification
