I searched here, did not find the list, so I will post. I will be going to Chaengwattana to apply for a 1 year extension based on marriage. I will bring: marriage cert, thai bank statement showing 40k+ monthly deposits, a screenshot of my TM30 done online, copy of my wife's ID card and house book, my passport with TM6, my 2x2 photo. Anything else? I assume I get the form from the copy shop downstairs. Is it the same form you fill out for a 1 month extension? Lastly, does my wife need to go there with me to drop off this stuff, or only when I pick it up 30 days later, or both? Many thanks for your guidance.
TLDR : Answer Summary
A user inquires about the required documents for a 1-year extension based on marriage at Chaengwattana. They plan to present their marriage certificate, bank statements, a TM30 screenshot, copies of their wife's ID, house book, passport with TM6, and a photo. Comments suggest additional documents may be needed, including photos of the couple at their residence and a hand-drawn map. Clarifications about financial requirements indicate a possible issue with banks statements being accepted, emphasizing that the wife must accompany the applicant during the submission but not during the pick-up.
