How do the income and bank balance requirements for visa extensions in Thailand based on retirement and marriage work?

The way the "seasoning" of funds works is;

-for extensions based on being over 50 for the first yearly extension you need the 800K baht seasoned in your account for 60 days prior to your application for extension. For every subsequent yearly extension you need the money seasoned 3 months prior to your application.

-for extensions based on marriage to a thai you need the 400K baht seasoned in your account for 2 months prior to your application.

- for extensions based on raising half-thai children there is NO seasoning of the 400K baht and it can be put into the account the day you apply if you want to.

-for extensions based on raising foreign children for the first yearly extension you need the 500K baht in your account for 30 days prior to your application and for subsequent yearly extensions it needs to be in the account 3 months prior to your application.

Don't forget the aging

60 days for first time

90 days after.

You need a copy of your updated passbook & a letter from the bank.

They prefer the letter in Thai.

They can be no older than 7 days but they prefer if it's the day before.

The money in the bank has to be there minimum 2 months prior your first application. after that 3 months prior. Pension or income must be certified by you Embassy.

It works easy. For Extension of Stay based on being over 50 years you need 1. 800.000 Thb on Thai bank account 2. Monthly income of 65.000 Thb certified by your Embassy 3. Combination of both with minimum 800.000 Thb. For Extension of Stay based on marriage with Thai National you need 400.000 Thb on Thai bank account or 40.000 Thb monthly income if from abroad certified by your Embassy if from inside Thailand with tax receipts.
