Pretty much only savings accounts available; some with fixed time options to get better interest.
Also Thailand imposes a 15% tax on interest earned.
I will try to renew with the monthly deposit qualification the 2nd year. If successful this would effectively eliminate the 800k requirement in a Thai bank. That money can certainly be invested in better ways.
agreed the IDP is nothing more then a translation document not sanctioned by any government entity.
However at least one car rental agency on Samui required it to rent a vehicle in advance online.
My other experience regarding the IDP was the Department of Land and Transportation seems to want it with my home country drivers license when I applied for the Thai drivers license
Krungsri will NOT do it on a tourist visa alone. Your father will need at a minimum the O or O-A visa, a Thai address with TM30 and then whatever else each individual branch asks for.
requires more documents. Police report, medical certificate, proof of Thai accepted insurance, financial bank statements, etc Not easier in my opinion.
