Report is due Sunday 2nd March. You can report 15 days prior or up to 7 days after that. You will need to report in person as it’s your “1st” report after entering Thailand.
As an aside to your question, if you buy a e-visa tourist visa to come to Thailand it will give you 60 days, but as an Indian national you can’t extend that.
Don’t pay and come visa exempt and you’ll get 60 days and you can extend that for 30 days at a local immigration office. Go figure the logic.
Would only be a few minutes to do. You pay the fine, they stamp your passport with the overstay stamp and off you go. The only issue would be if there was a queue in front of you doing the same.
Perhaps allow for an extra 20 minutes just in case but I doubt you’d need anything like that.
Works for loads of people. Most sites give a real PNR valid for a couple of weeks. They are just made up tickets that are real if checked but cancel out after x number of days.
The need for an ETA has been suspended indefinitely. For a US passport you don’t need a visa for a stay of 60 days or less. 90 days if you get an extension at a local immigration office.
