Just attempted to apply for extension of a type-O based on marriage in chaengwattana and was turned away for now, but learned a few things that might help others:
- the initial information given to us by an immigration officer was wrong, samut prakhan will not cover those based in prawet.
- for some reason having Thai kids makes the process more difficult (one would think otherwise) as we are now forced to get house registrations for them. the fact that the news says these are not requested August onwards doesn't seem to be relevant.
- some of the family photos we took were rejected as my face was too close to the camera lol
-getting the kor ror 22 is now also proving to be a bitch. Updates to come...
TLDR : Answer Summary
The user faced difficulties while attempting to extend their marriage-based Type-O visa in Chaengwattana. Key issues included misinformation about jurisdiction, complications arising from having Thai children which require house registrations, and rejection of family photos due to proximity. Additionally, obtaining the 'Kor Ror 22' document has been challenging.
