（1）根據USCIS關於I-130的介紹，給母親辦綠卡，隻要交申請費，I130表，申請人的公民證書複印件，和申請人的出身公證的複印件。關於父親，隻要多交一個父母的結婚證書的複印件。並沒有提到要父母的出生公證。但是論壇裏很多帖子談到要父母的出生公證，所以想請老師們確定一下。
-I-130 filing does not need parents's birth certificates, but their I-485 filing do need it. So, you need to prepare it.
（2）PJANG老師的BLOG，建議B2簽證的父母在停留期作廢一兩月前再申請。但是如果等到停留期，還沒有I130的消息，那是應該繼續呆在美國，還是要離境？
-Not need離境, and their unlawful presence does not affect their GC application.
（3）如果I130 和I485同時遞，那體檢可否等I130批準了之後在做？
-Yes, but don't send it until USCIS requests this document (USCIS will send you RFE for it and then, you can send the physical exam report to USCIS).
