so what… whatever you’re doing here, Thai immigration laws apply to you; and the law says you have to provide a printed copy of your evisa, what can’t you understand in this statement ?
did I say it makes sense ? NO. Is it the rule ? YES. So you’re entering a country that fixed some rules, you agree to the rules or you visit another country, that’s as simple as that.
Participant(e) anonyme not the first time. First time of every entry in person or third person or paper registered mail, then online. If you exit and re enter, you have again to do it in person or paper mail. The thing to consider is the paper mail thing will be returned within one month to the registered address so it can be used only of stable. If not (like me, traveling around in hotels) you need to do in person or through agent
If you have a stable adresss for more than 1 month after the 90 day report, just do it by registered paper mail at post office. Costs 70 baht with ems tracking, process and address to send is in Bangkok immigration website about 90 day report, have to do it 14-15 days before the 90 days and you will avoid queue ;)
