回复：请pjiang老师帮助485

1. 如果第一份485在pending，递交第二份485 Form 时：
Have you ever before applied for permanent resident status in the U.S.?
如何填？
- [x] Yes
mm/dd/yyyy Petition pending with xxx (NSC/TSC)
using your receipt date or submission date when receipt is not received yet

2.pjiang老师和大侠们，如果递交第二份485，必须填A number吗？填 n/a 可以吗？会有什么后果？
感谢！！！
- It is said that second I-485 must be held until an A# from first I-485 is available to avoid dup A#, while the 485 Procedure indicates that the A# is checked against database to avoid dups before data entry. Personally I have not filed 2 I-485s, so I am in a difficult position to suggest you.
