Renewing extension for 'support thai wife', using the 400k in the bank account method. However, I also work in Thailand.
Is it normal for them to require all the financial documents from my school - tax returns, withholding tax receipts, etc... As well as my bank account documents?
I've never needed all that before - previously the just asked for a copy of my work permit, a letter from the school, and copy of my bank statement showing salary going in
TLDR : Answer Summary
When renewing a visa extension based on marriage to a Thai spouse, especially using the 400k bank account method, it is common for immigration to require a variety of financial documents. This can include tax returns, withholding receipts, and bank account statements, particularly if you also earn a salary in Thailand. While prior processes might have been simpler, increased document requests reflect the varying requirements across different immigration offices.
