Couple of questions about 90 day report.
1. I heard you can do the first one in person but all the next ones online. Can someone give the URL for this?
2. Do I need to do the 90 day report at the 180 day mark? So if I do the extension should I also do the 90 day report or since I am doing the extension the 90 day is not required?
TLDR : Answer Summary
The 90-day report in Thailand needs to be done each time you spend 90 consecutive days in the country. The first report can be done in person, but subsequent reports can be submitted online. It is recommended to file your report 14 to 7 days before your 90-day mark, and the specific portal for this is https://tm47.immigration.go.th/tm47/. If you apply for a visa extension, your 90-day reporting requirement resets, but it is advisable to complete the report unless you are doing a border run.
