Coming up on yearly extension of stay for retirement and my 90 Day Report 20 days after. Is it 7 days after the 90 Day Report date my grace period. Also I want to avoid going all the way to Bangkok and getting the affidavit of income. Can I show just an updated bank book in only my name with the required amount. The money has been there, over 850k for over two years. Any other financial paper required?
