Thailand

One of the photographers I deal with is in Thailand at the moment, but he can't use local models, because it's illegal for a foreigner to be a professional photographer in Tailand!

Here's the king as pictured on a bank note. It is said he carries his camera everywhere.

31 other professions are apparently also barred for foreigners in Tailand, including hairdresser and designer.

I'm guessing it's meant as protection of trade. I haven't had much luck finding confirmation of these data though.
