回複：父母拿到綠卡回中國過年，本來打算半年後回美國的，因為家裏出了事，需要留在中國，應該怎麽樣才能保留綠卡呢

As on as they come back to US within one year, their GC will be fine. If they stay in China for > one year, their GC will be valid unless there is something uncontrol to prevent them to return to US such as serious illness or natural disaster.

所有跟帖： 

• 回美後可以辦回美證就可以在中國兩年是嗎，二個月可以辦下來嗎，回美證辦完一次後還可以再辦嗎，需要在美國報點稅比較好點？， -ericandowen- ♀ (0 bytes) () 03/11/2011 postreply 15:33:26

• 給你父母提個醒，盡量別太長時間呆在國內 -ann1sky2- ♀ (199 bytes) () 03/12/2011 postreply 17:43:32

• 謝謝，也是。在申請RP之前還是要半年內回來的好，不然 -ericandowen- ♀ (49 bytes) () 03/13/2011 postreply 13:32:33
