It is for sure very stressfull to amass all the papers required to get the marriage visa and so much easier to get a retirement visa. I have applied for it 7 years now. The funniest one was update your bank passbook. I had no transactions from my bank at the time so saw no need to update as there's nothing to print out. The I O told me I must update for that day how nonsensical is that. So I had to go to the bank, pay in 500 baht and update the book.

mate , a marriage visa is a bitch of a thing to get, sooo many hoops to jump through. If you can put 800,000 in your bank account or have at least 65,00 baht a month paid into your bank account, get the retirement visa soo much easier.
