I've had enough of visa problems. Looking over my shoulder. I'm 50 this year and I'm going to do my own retirement visa as I have the time to do it.
I suggest you come in on a tourist visa and extend and do your own. Other than that use an agent. I'd rather not give more money away for something I can do myself.
If you prefer an agent, Siam legal give free advice before you commit to their services. There based in Bankock and Pattaya. High end professional service from my experience.
I had an old Thai licence and went to driving licence office. They told Me if I was Thai they would give me.a new one. I have to go to my registered provience.
They.told.my Thai wife they would give her a new one as she is Thai
Your payment is for them doing lots of paperwork...and setting you up and covrering you ass . Your choice not to doall the classes ? Up to u? You don't get visas unless it's a retirement visa for less than minimum 35k plus some additional costs.
