You can go to Savanakhet, Laos, get a multi o year visa based on marriage, no funds needed except 5,000 baht for the visa. You will have to leave the country, do a border run every 90 days though. You will also have to pay 1.500 baht each time you leave for the Laos visa
You could go to Savannaket in Laos, get a 1 year non o visa based on marriage, no funds required but you do have to pay 5,000 baht. Apply Monday to Friday before 12.00 and pick up next day (Tuesday - Friday) after 2.00pm. Leave the country every 90 days
If allan Duffus had read the original comment, he would have seen that the person had gone to Savannaket, which is in Laos. So, once he has his multi entry visa, he MUST leave the country every 90 days. Get your facts right before writing misleading comments
800,000 baht in the bank 2 or 3 months prior to application, and it must still be in your account on day of application then you can take it out. Then make sure you have the amount in your bank account for every other application, or, 65,000 baht income every month
I can;t see any problems, but make sure you go on time. Immigration will be closed on the 30th/ 31st December and the 1st January, maybe the 2nd of january
