If a person has had criminal records in their native country and they come to the united states and get permanent resident card. After a year one year of their stay the FBI receives an arrest warrant from their native country to return them back to that country so they can be prosecuted in their native country as they are not yet citizens here.
My question is what will be the procedure? How long will this take I need an estimate. Because I have heard that for illegal aliens it normally takes from 30-90 days and in some cases 180 days and some of them get to stay here despite their criminal records. Will they simply deport the person upon receiving the letter or will they have their own invistigation and take the person to court.
What are the chances for the person to be able to stay in the US?
any help is really appreciated
