）如果母親黑下來了，兒子還沒有來得及給母親申請綠卡。因為特殊原因母親回中國去了。那末母親在美國非法滯留的曆史如果超過180天
ANSWER:
就算是當兒子拿到公民後，給在中國的母親申請綠卡，母親也要接受3-year or 10-year bar的移民簽證（落地綠卡）的限製。 TRUE OR FALSE?
-True. She can not get the immigration visa or none immigration visa in China due to the bar.
2）如果母親黑下來超過了180天，兒子才開始母親的綠卡申請。因為特殊原因母親在綠卡拿到之前回中國去了。回到中國的母親也要接受3-year or 10-year bar的移民簽證（落地綠卡）的限製。 TRUE OR FALSE?
-True unless USCIS approves her green card after she leaves (USCIS probably will deny her green card in this case, so it is very risky). She has to get the green card within US before she leaves US, then the 3- or 10-year bar will not apply to her, a green card holder. Otherwise, the bar will work.
