My wife is stuck in Venezuela - Airports are shut, no flights in and out - People allowed out a few hours daily to buy essentials. It looks like she will not be able to get out of the country and will wind up staying there over six months.. She does not have the guts to walk into Columbia illegally - the crossing is very dangerous. Contacted the U.S. Embassy in Columbia. Cannot help. What can I do to make sure she does not loose her permanent residency, and to insure her return to the U.S. without problems when she is finally able to do it?
