8老師，本人剛剛寄出I-751申請，下月初去打指紋。根據網上的信息大約需要3--6個月的時間收到10年綠卡。請問在這幾個月期間如果想回國，需要做什麽準備？
-If your conditional green card epxires or will expire before you come back to US, you need to bring your passport, the copy of your conditional green card or I-485 approval notice and the I-751 filing receipt to the USCIS local office to get the green card stamp on your passport before you leave US and then, use the green card stamp to travel to China.
我的conditional GC會在6月初到期，請指教 Thanks!
