reality is that you need to find a way to deposit 400,000 Thai baht in a Thai bank account in your name only to get the one year extension of stay based on marriage to Thai.
The border runs and visa runs are gone.
Plan ahead now.
The funds do NOT have to be left on deposit for the entire year...
But must be during the usual month following your application for the one year extension of stay based on marriage. Then spend it or draw it out... Just have it redeposited two months before your one year extension of stay ends.
