What are the requirements for obtaining a 1-year married visa in Thailand regarding bank deposits?

Do you know that your Immigration Office will accept the 40k monthly international transfers for year 2 onwards as many will not, it has to be Thai salary per month?

I just did my 2nd year extension and the 400k baht was required to be in the bank for 3 months (Korat immi).

You need the 400k baht in your bank for 2 months before you can apply for the 12 months extension of stay. Whether you can show 12 months worth of 40k international transfers next year will be down to your immigration office, an increasing number are only allowing this option for income earned in Thailand

The 400k has to be in the bank for at least 2 months before you can apply. Once your application is accepted you will be under consideration, which is usually 30 days, and you must keep the 400k in the bank during this time. Meanwhile you need to start transferring 40k baht every month so you have 12 complete months before you apply for your next extension. Make sure your transfers show as international. Once you receive your 12 month extension you are free to remove the 400k

The deposit is for the first year and once you got your 1 year visa you don’t need to keep that 400.000 anymore. Next year you can use the deposit every month

You have to put the in your bank account to get the first extension. At the same time make monthly deposits of baht to get your second extension based on monthly income unless your embassy will certify your income.
