yap, might as well just fly in 2 times for 3 months or 3 times for 2 months and not deal with any of the drama. VN offers 3 month tourist visa and I never had any issues there. Also they aren't chasing people over income tax unless you work locally.
TH just wants the money and not the foreigners, make sure to stay in TH under 180 days during a calendar year so you don't have to deal with the income tax BS...
5 reviews, two of them seem to be from clueless individuals, one of which wasn't happy that the insurance company didn't have direct billing with the hospital they went to - not a major issue as its pretty standard for most insurance companies.
