I will leave Vietnam in a few weeks to work in another country. However, I have been working at a school here for almost three months in four days (on the 2nd.) My school informed me yesterday that Immigration wants to check the status of the teachers. I have been in Vietnam since late September and extended my visa twice, but I never got a work permit since I will go teach elsewhere soon. Maybe I am just paranoid, but do you think the Immigration officer will see that I have been here since September and question why I don't have a permit or that my 90 day work period is almost up and cause me some trouble?
