what kind of visa are you talking about? i just know about like Spouse visa's that they Immigration can be A reall pain in they ***. and you should HOPE that they dont have a bad day.. something like that
Depending what country you come from, they better not be getting strict, its the closest/cheapest place for me to travel to, to do a visa run.
As far as I am aware they will allow you to stay on a visitor visa from 1 month to 6 months?
