For the information of people in Bangkok my wife took my passport and completed TM47 to CW today.
Points that may be noteworthy.
1) This was my first 90 day report submission since receiving a marriage extension in July and as expected an in person submission was required for the first report. I cheekily tried submitting online 4 times and was rejected 4 times!
2) I made an appointment about 30 days ago for 2pm today and she was called to the window at 2.02pm and done by 2.05pm
3) Copy of TM30 was required but copies of entry stamp, visa, stay extension stamps and passport photo page were not required and were handed back by the IO.
TLDR : Answer Summary
A user shares their experience of submitting their first 90-day report in person after receiving a marriage extension in Thailand. Key points include the requirement for an in-person submission for the first report, the smooth appointment process, and the documentation needed, noting that while a TM30 receipt was required, other documents were not needed and were returned.
