years ago. he made the stupid choice, or getting involved in selling drugs with my brother in law. this happened over 15 years ago, he was only in jail for a few days. he has not commited any other crimes or been in trouble with the law. he has had his green card since he got here over 20+ years ago. he never became a us citiznen, as he was afraid of dredging up the past and getting deported. but the other day he randomly got a letter stating that there was a risk he could be deported because of his criminal record.....
he has told this only to my sister and not to me so i cant be asking him questions. but can he do anything? my brother has 4 children, 2 of which are very young (one is 4 and one is 5 years old) he has a wife and he living with his father/mother in law. and his son from his first marriage, who just turned 19.
he is a hardworking good man, that made a choice he shouldnt have made, but it has been so many years. can he still be deported for a crime that occurred so long ago??? help!
