An immigrant can even be deported for failing to advise USCIS of a change of address within ten days of moving. In the past, USCIS almost never did anything about this. However, with increased security concerns, USCIS has begun using this rule against people it wishes to remove from the United States. You can now use USCIS's online service to notify it of your change of address.
上麵說如更改地址需十天內通知 the immigration authorities。我不記得我搬家後有沒有通知 the immigration authorities。如果現在改(5 年後)可不可以?我的綠卡12月到期。
另外我的前夫申請的綠卡,我也就以spouse的身份得到了綠卡。 我們結婚八年後分開,會不會影響我renew綠卡?
