Hi I am new to this forum!
My lawyer filled out my forms and I mailed my application on October 15, 2012
USCIS received it on the California Service Center on October 19,2012
On October 25, I received an I797C and a biometrics schedule
My biometrics was scheduled and done on November 13

I have a clean record and for my original documents, I submitted my I-94, transcripts dated 2008-present, a letter from George W Bush for an award (ha!) dated June 2007, a copy of my passport, and birth certificate. I had a legal F-2 visa until May, 2012 (whew!) So I'm glad everything is working out quite well.

My question is, what is i797C and how long will I get my approval after my biometrics? I am 99.99% positive that I have no malicious police records.
Also, how long will the wait be for my SSN? I NEED it for some scholarships and college apps/loans.
Thanks so much everyone!
