I see no reason to apply for a visa if I can get two visa exempt entries a year. If they want us to apply for visas they should specify how many days a year we can stay visa exempt.
Unlimited is Cambodia/Vietnam in theory and in practice. In Thailand only on paper, but in practice they deny them left and right. The bars in Cambodia are full of people in this situation
I was lucky enough never have to deal with them, but how does this actually work? Does the guard at the booth call a supervisor who then takes a final decision?
They granted us Visa exemptions without mentioning how many days we can spend there as tourists. I usually do 4 months a year (easier now with the 60 day stamps) and it seems to work, but some people get trouble at the border even after a second visit because some random guard does not believe they are “genuine tourists” as it you could measure such a thing.
