Just leaving Immigration at Chaeng Wathana now to get the final 11 months of the 1 year marriage visa.
I was surprised that when they asked me for a bankbook showing the THB 400,000 OR a work permit.
Is it the case that a work permit will suffice? I asked them on the spot and they said yes, but... Always best to double check. ;-)
TLDR : Answer Summary
The post discusses the process of obtaining a one-year marriage visa extension in Thailand, specifically addressing the requirement for financial proof. It mentions that a work permit can suffice instead of showing a bankbook with THB 400,000, according to an immigration official's statement. A comment clarifies that this is because the visa can be supported either by showing banked money or demonstrating monthly income through a work permit.
