8 老师，你好， 我已经拿到公民5年了， 现在想给父母申请绿卡，有几个问题请教您
1. 母亲已经在美探亲，还有4个月到期。可不可以先给母亲申请绿卡，以后在给父亲申请。会不会影响以后父亲的申请？
-It hard to say whether it will affect your father to enter US using B-2 visa. If he can enter US, it is OK to apply for green card after a few months later (had better do it about 3 months later after he enters US).
2. 父母都有10年探亲签证，在办绿卡期间，母亲可以用探亲签证来回出入吗？
-No. She needs to apply for AP to travel.
3. 母亲办绿卡，是不是先办130 再办485？
-Can file both at the same time.
可不可以简单介绍一下具体的步骤和程序。
-Follow the I-130 and I-485 Instructions. You also can Google it using key word such as "父母办绿卡".
非常感谢！
