the QR code is tied into your exact passport number, as the immigration officer will be able to see it on their screen as well, so you can't use a generic QR code or one not tied to your specific online submission.
what does going to immigration to file your TM30 have to do with how long you can stay in Thailand? At the time of filing, no one cares if you say you are staying 6 months or 6 years. That's not the purpose of the TM30. It's just to inform that a foreigner is staying at a certain address within 24 hours of arrival. It has nothing to do with permitted length of stay.
you're completely using the wrong term. You aren't renewing anything by doing a 90 day report. All foreigners staying in the country more than 90 days since they entered Thailand, regardless of visa type, must file a report of where they are living every 90 days with immigration. It doesn't extend, renew, or have anything to do with how long you can remain in Thailand. If you exit the country before 90 days, you don't need to file anything, and each entry starts the count over again.
You are constantly posting and commenting comparing how Thailand is worse than other international destinations. What's the point, you should go those places instead. You are also frequently wrong about whatever you claim in your post, and being corrected. Just like this post where you claim Turkish is the only airline flying to Thailand. It's almost like you're being paid to badmouth Thailand since all you do is say how bad it is or how its policies make no sense.
I agree, I notice he's constantly posting and commenting comparing how Thailand is worse than other international destinations. What's the point, he should go those places instead. He's also frequently wrong about whatever he claims, and being corrected. Just like this post where he claims Turkish is the only airline flying to Thailand.
interesting, as DLT's own website says "ORIGINAL PRESENT RESIDENT ADDRESS IN THAILAND CERTIFY FROM EMBASSY / IMMIGRATION BUREAU (VALID FOR 1 YEAR) OR WORK PERMIT (WITH PRESENT RESIDENT ADDRESS IDENTIFIED) AND ORIGINAL PHOTO COPY OR WORK PERMIT WITH ORIGINAL AND PHOTO COPY"
DLT's own regulations on their website show it is required, and I can confirm it was needed when I renewed my license this week. Either residence certificate or work permit book are accepted.
