My EAD application got returned because of no I-485 copy

I followed the instruction on the following link:

EAD 材料清單如下：

Form I-765

Copy of I-485 Receipt Notice － 僅單獨提交的免費 EAD 申請
Copy of Last EAD (front and back) － 沒有的話用護照 copy 代替

Copy of Approval Notice of EAD Application (Denial notice if applicable)

Two 2" x 2" photos (name & A# on back in pencil)

新版的 I-765 有下列變動：交費的 EAD 不再需要 I-485 收據， I-485 的 EAD 不再需要 I-94 了.

It turned out that they sent back my application package with the notice which checked category G: "We were unable to systems verify that you have a Form I-485, Application for Adjustment Status, on file. .... Please resubmit your application and applicable fees along with proof of your earlier filing of your form I-485."

By the way, I did submit all required documents and $340 check except I-485 notice copy. I guess that there was no new version of I-765 without requiring I-485 copy. In the future, we better submit everything to INS for EAD application.

Anyway, I still appreciate pjiang's blog. I have learned a lot from his posts. Merry Christmas and Happy new year to everyone in this forum!
