Receipt date: May 1, 2006

I received the email updates on June 5, and received the formal letter requesting more information on June 9.

I am using OPT since last summer and worked part-time for a while.

My understanding is that pay slips can prove you are in the US legally. But I cannot find them. What should I provide in stead?
