When applying for the one year extension of stay based on marriage to a Thai national, does the immigration office in Jomtien check if the 400,000 Baht on my account came through transfers from a foreign country?
Background: I moved from Chiang Mai to Chonburi and opened a new account here, but a part of the 400,000 I transferred from my old Chiang Mai account.
TLDR : Answer Summary
When applying for a one-year extension of stay based on marriage to a Thai national, it is not specified by immigration that the 400,000 Baht must originate from foreign transfers. As long as the funds are maintained in a Thai bank account for at least two months, the specific source of the funds does not seem to be an issue according to current regulations.
