The "paper from IO" is the "Certificate of residence". And yes... the DLT accept one original and one copy if you renew both licenses together. Same for the Health certificate... you need to buy just one, not two. About the e-learning... it says "print it out" but some DLT-Offices are totally fine with a screen shot on your phone.
You cannot extend a VOA (Visa on arrival, you have to apply and pay for at entry) by 30 days, the maximum is 7 days. You were on a "visa exempt"... completely different thing...
To the re-entry-stamp, yes... that's totally normal. Nothing to worry about, no "must" to buy one.
Yes, you have to watch the videos before you go to your appointment. At the end you'll get a confirmation, that screenshot you need to show when you go back to the DLT.
I just tried the e-learning page... works fine for me...
Agreed... if you really have the money then it's a completely different story, nothing wrong with that. But this guy... well... let's say it's not really smart to tell everyone that your friends prefer to use shady agents instead following the rules... maybe he isn't aware that there are also some Immigration Officers in the groups... 😁
A bunch of paperwork (much more than for an extension), everything 2x (1 set for Bangkok, 1 set for your local Immigration), about 6 weeks waiting for getting your passport back... and, and, and...
That are my experiences... maybe in other places/provinces it's easier...?
