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.
上面说如更改地址需十天内通知 the immigration authorities。我不记得我搬家后有没有通知 the immigration authorities。如果现在改(5 年后)可不可以?我的绿卡12月到期。
另外我的前夫申请的绿卡,我也就以spouse的身份得到了绿卡。 我们结婚八年后分开,会不会影响我renew绿卡?
