Well my marriage is not going to happen but the visa has been issued...can the visa be canceled so it cant be used or do I have to just let it expire. I’m going to call the embassy tonight and find out what I can do but I thought someone here might know too.
I think even if you tell Homeland security, I don't think they would try and stop the visa if she/he has it in hand. I don't know if they will enter her name into the computer at the POE.
If you don't marry them within 90 day. It will expire and then they will be out of status and must leave the country or they will be illegally in the Country and at risk to not be able to receive consideration to return to the US for 10 year.
If you have no intentions to marry that person, don't worry, you aren't on the hook for anything, but you might want to tell USCIS(ICE). IMO
