Many years ago I made a return trip from Bangkok to Hong Kong, while on a visa waiver entry. In anticipation of being asked in Hong Kong on the way back, I had bought a train ticket to Malaysia before leaving Thailand. It all worked out exactly as expected, no problem when asked for onward journey proof.
If I were on a short trip here (I am not), I might feel it would be ok to simply leave the country before the end of the 30 days that I should have been stamped in for. After all, travellers should know the immigration requirements while planning their travel. What are your thoughts on this?
I changed my extension type last year from marriage (basis of my original non o visa) to retirement. This was at Samut Prakan IO. I asked at the time if it would be possible later to change the reason for extension to marriage, and they said yes.
It is worth noting that they will cancel your previous extension when you change the reason, and reset the extension date to the date of application. My original extension expired in November and after changing it now expires in September, so don't go too early to make the new application.
Next time I will submit as early as I can, 15 days before. This should give them a chance to process it. Going in person isn't a problem, and you have up to 7 days after the due date to do so. I wonder if it was a coincidence them rejecting after they had approved, or whether it was necessary in their system. As they don't give a reason and only tell you to go to the IO in the rejection email, I do not know.
I submitted an online report at the newest webpage version. After 9 days at status pending I went to do it in person at Samut Prakan IO. This was on the 15th, the report was due on 12th. So after getting an approved report at 10:30am at the IO, at about 16:00 I had a reject response from the online system.
My app still incorrectly shows overstay, which I believe it pretty normal as TM do not update their database. Better luck next time I hope.
I should have waited until nearer the old extension due date. This is why I mentioned the possibility to renew 45 days earlier, which is fine if you don't change the reason.
Would the advice have been to renew on the next extension due date?
