Why is Roi Et immigration requiring 3 months of bank statements and a letter of guarantee for marriage visa extensions?

A recent inquiry about the Roi Et immigration office's request for three months of bank statements and a letter of guarantee from the bank for marriage visa extensions has raised some concerns. Community members discussed that while standard procedures have not changed, some officers might add extra requirements not officially recognized. Typically, 400,000 baht must be seasoned in a Thai bank account for at least two months prior to an extension application. However, there are inconsistencies in enforcement across different immigration offices.
