多謝8老師這麽快回帖。他們過期居留會不會影響他們將來回國和再入境呢？
-They can use AP to travel to China and reenter US before they get the green card if their overstay is less than 180 days before they file I-485. If their overstay is > 180 days before they file I-485, they have to wait for the green card is approved and then, use the green card to travel to China.
