Anonymer Teilnehmer 452 Every "Alien" staying more than 90 consecutive days in Thailand has to report their address every 90 days, doesn't matter which kind of visa one hold. The only exemptiopn is the LTR, they must report just anually.
2) you can go (in person) to any DLT office, so... not possible from abroad
3) you can apply from 3 months before the license expire, if you are up to one year late there is no difference in paperwork or required tests to a normal renewal
I changed from extension based on O/A to a new O in country and used the old / local money... was no problem in Phuket... no need to transfer new money in the account.
I use my money for many years now in every "season" and fill it up later from another (local) account... never had any problems with that. Btw... it's just 2 months before application, but 3 months after the extension is issued.
The latest "fetish" in the DTV-Community... lamination. Just a printout (even a downsized one) isn't good enough anymore... it has to be laminated to be successful... 😁
No problem at all. If you transfer the money in two steps (400k each) you are safe with the requirements, let some days between the transactions, just in cases. Next year you just have to bring two bank statements for your extension to show the continuity.
