What are the requirements and processes for obtaining a Thai spouse visa for US expats?

1) the US embassy does not certify income

2) the ONLY thing Thai immigration will accept is income certified by your embassy. See answer #1

3) in your name only

4) it doesn't matter where the money comes from.

If your embassy does not certify income the ONLY way to get the initial non-O 90 day visa and first 1 year extension is with banked money. This means you need 400,000 in a Thai bank account in your name only.

Once you get your initial 90 day non-O visa, start transferring 40,000 baht each and every month into your account from overseas. You cannot miss a month even by a day. You need to be able to show you received this for 12 consecutive calendar months for next year. Therefore it's not advisable to let your social security go directly to your account and assume that will work as sometimes these payments are delayed (holidays, government shutdowns, etc). It's better to manually do this every month so you know it's done.

You'll use your 400,000 to get your non-O and one year extension and then you can spend this money.

Next year you'll show you have 12 months of transfers of 40,000 baht so you can use the income method instead of the 400,000 in the bank.

This is the only option if your embassy does not certify income.

*Please note that even if you already had this all setup a year ago and have been making the monthly transfers, it doesn't matter. You can only get the initial 90 day non-O visa and first 1 year extension with 400,000 in the bank.
