Hello all , I wish to seek some expertise regarding an RFE I received. I am currently F1 STEM OPT, and applied for AOS with I-485. I received an RFE for proving that I was in lawful legal status and the time of applying. To me it's bizarre because I thought I had covered all of the bases. Here are all of the pieces of evidence I provided:

1. All I-20's from when I started my studies to current.
2. STEM OPT, post-completion EAD card, front/back
3. I-765 approval and receipt notices for both
4. Paychecks and offer letter for my job.

I believe that I may have received this RFE because the "current" I-20 I submitted had a "requested" for STEM OPT on the second page. Any advice would be appreciated, on what other pieces of evidence I can show is appreciated. Thanks!
