Non O Multiple Entry based on marriage with a Thai
After all my stamps out and in had my 15 month completed
And went to my local Immigration Office in Sisaket for a 60 day extension visiting family. The only needs was copies from my wife's ID card the tabien ban and our marriage certificate . It took them 15 minutes and all done. Fee 1900 Baht. That means you can be on this kind of Visa here for nearly 17 month without any proof of money. The visa was made in Savanakhet.
