回複：緊急請教

我485的APPROVAL NOTICE 已經收到二個多月了，但綠卡未收到，
-Take your I-485 approval notice and your passport to the USCIS local office to get a green card stamp on your passport and then, you can go to China and work. The GC stamp has the same functions as the physical green card.

現在我想回國，另我還有有效L2簽證，AP 也有，我可以回國嗎？需要辦什麽手續嗎？
等我入境時，應持什麽入關呢？
謝謝！
