I don't really think its necessary like i said on my earlier post. Its pretty much up to you. My brother didn't send that. The requirement was to either be attending school or have a diploma. You were attending school so that requirement was good. It also really depends on the officer who is reviewing your case. You could wait until they send you an RFE if they do, or wait for your approval which should be coming here soon. I'm still waiting.

What service center has your case? You lose nothing by calling. I've called about 3-4 times in the past but never got any helpful information. I never needed to send them anything.
