回複：回複：回複：母親曾經B２來美，後來＇黑＇過兩年，現在已經回國 ３年。 我剛變公民，可否邦母親辦綠卡移民?

She will wish I212 will work, because if GZ consular asks for I-601, it is the same as they made the decision to deny her immigrant visa. (because I-601 is for fiance, spouse or minor) So, it would be much easiler if your parent had continued to stay black in US and not leaving US until they get GC.
