Guys, who was at Chiang Mai immigration recently? What is the list of documents for visa extension with embassy letter? This is for those who entered Thailand on tourist visa or visa stamp. Many thanks in advance!
TLDR : Answer Summary
To extend a tourist visa at Chiang Mai immigration with an embassy letter, you generally need: two photos, two copies of every page in your passport, a TM30 form (with a Chiang Mai address), and two copies of the embassy letter. Applicants must also be patient during the process, which typically occurs at Promenada immigration that requires transportation. After obtaining an extension, questions remain about future extensions and the necessity of embassy letters, which may continue to be issued depending on the applicant's situation.
