My husband and I have been married for 2 years. We have already started the citizenship process. He was never in the states illegally he was here with his mother that has a working visa and is an ESOL teacher. He has a work permit but its about to expire. He has also received his green card. He has 2 former drug charges (possession of marijuana) misdemeanors that he received when he was 17 and 19 they both were deferred adjudications. Would he have the risk of not getting let back into the country if we traveled abroad? Does he need a pardon from a judge?
