@Ben *******
people laugh at concept that seems absurd to them and doesn't make sense.
I don't know what (tourists) visas you need to "activate" in any country. When you have a tourist visa you typically have it... There's no activation.
I do believe that some countries have worked for mates and work visa that you might have to leave and come back. I don't think that's the case in Thailand?
In USA the work permit Visa you actually need to go or used to have to go abroad to consulate abroad to actually get the visa in the passport. I don't know if it's still the same rules but it used to be those rules in 2000 to 2006...
