回复：为父母办绿卡，哪位高人能指点一下？多谢了！

父母于今年11月来美，明年4月回国。打算为二老申请绿卡，请问如果现在办绿卡，是否会影响他们回国后再次入境美国？

-Yes if they use B2 visa. So, they had better get the AP for the travel.

 

申请绿卡后多久能拿到旅行证件 （AP）？

-Immediately apply for the AP when you file I-130 and they file I-485 together (all the I-130, I-485, AP applications are filed together at the same time).
