Hi Matt I am married to a Thai and have recently moved over here. I got a 90 day marriage visa which I will extend in Thailand (processing now) To get the visa I needed proof of finances. Marriage, some where to stay They also ask about validity of relationship But everything is well presented on the Thai e visa Web site If I could navigate it it can't be that hard
From personal experience Be on site with your wife Oversee the work As nice as it sounds don't employ her aunties brothers son who builds houses. Their is a reason he's cheaper
Just going through my first 1 year extention and one odd thing they did ask for was evidence of bank account recently used Girl at immigration said just take some cash out and then put it back in the following day Did that so far so good
