How to cancel Vietnam's five-year visa exemption?

As far as I know, a five-year visit visa to Vietnam is a multiple-entry visa, and the holder can enter and leave Vietnam many times within five years. The validity of the visa is not affected by the holder's marital status, so even if divorced, you can still use the visa to enter and leave Vietnam. The other party can't cancel your visa directly unless they have a legitimate reason to complain to the Vietnamese Immigration Bureau, such as providing evidence that you are suspected of violating Vietnamese laws or visa regulations. They can't cancel your visa without legal reasons. If you have any questions or need further help, I suggest you consult the official website of your local Vietnamese embassy or consulate or immigration bureau.
