My friend who is married to a USC filed her I-761 for removal of conditions some six months ago. She got the 1 year extension letter and did her Bio. Her son who is now 12 years arrived in the US about two year ago when her USC filed for him. The boy's PR expires end of July and they're wondering how to renew or remove the conditions of residence for the boy. Any advise will be much appreciated. Thank you for reading
