I am curious about the criminal background check and if my record will prevent me from obtaining a work permit in Vietnam. In the guide on this site it states "Expats must not have a previous conviction for infringement of national security, must not be facing examination of penal liability and must not be serving a criminal penalty as prescribed by Vietnamese or foreign law." But on other sites it says a "clean" background check in needed. I have an assault charge for 7 years ago that resulted in $250 fine. Will this make it impossible for me to get a work permit? Advice would be greatly appreciated.
