Report from Koh Samui:
Task: extension based on embassy letter, after non-o + a few covid extensions.
Passports: 1 Ukrainian, 1 russian.
Documents needed (TWO of each):
- TM7
- STM
- Acknolewdgement of overstay penalties
- copy of 1st passport page and all pages with current stamps/visas. Strictly horizontal on A4 (specifically states that).
- copy of TM6
- letter from embassy
- printout from Google Maps showing house location and coordinates (longtitude and latitude)
- TM30
- photo
For russian passport, have to bring original letter + 1 copy (since you get those letters in person). For Ukrainian passport, in addition to letter printout (letters are sent by email by consulate) they also asked for a printout of actual email text translated into English via Google Translate.
Process was super tiresome, probably 10x longer than covid extension - we came at 8:35 with all forms already filled in and all documents ready (except for those extra printouts), spent 2.5 hours.
Got under consideration stamp for 17 days (April 4th).
