Re: Thai immigration laws are complicated (PM Mailbag Friday, 19 September 2014) – My experience is slightly different. At various times I have had multiple entry visas, non-I O visas, work permits, etc. Never had that much problem. The requirements are fairly straightforward. Onerous? Maybe. But it was easier than getting my wife’s visa to move the US.
I have seen a number of foreigners who have had problems getting a Thai visa. But in all those cases they were trying to find a way around the system.
Play the game straight, follow the rules, it’s not that big of a problem.
