We know someone working here and we believe they have an expired visa. He married a US citizen but then divorced. We have been told his visa expired years ago. Does anyone keep track of this info and try to have these people extradited back when it is expired? Also, this person has several DUI's which to me would have been a red flag and he would have been deported then?
A person's immigration status is not public information.
That is none of your business.
