我在申請婚姻綠卡。已麵試過，在移民局網站上已看到綠卡業已批準。綠卡將於60日內寄給我。目前有一封Notice 正在途中。我最近一周準備回中國，機票已在手上。我可以出境嗎？還是需要得到移民局的批準？望老師不吝賜教。
-Two choices for you:
1. print out the I-485 approval information (e.g. email or online status) and hten, bring it with your passport to the USCIS local office to get the green card stamp on your passport, then use the stamp to travel. Tell the IO that it is urgent for you to travel and you can not wait for the physical green card.
2. Just go to China and ask someone receive the card for you and mail it to you in China. Then, use the green card to come back.
