Beleg

Same case here.  SRC, received waiver letter earlier. Glad it wasn't an RFE.

My wife is SRC and didn't need Biometrics. Last month when I did the E request for the extension letter, I also requested the biometrics in the same request. The next week we received the extension and a letter that they would use the biometrics on file. 
However only annoying thing is the myaccess site only shows the status as case received etc. It didn't update after the letters were sent out.

Does anyone know if you have to get your passport stamped if you got a receipt text but nothing else?
I mailed my wife's docs on January 19
Received an SRC receipt number via text on the January 25.
Case status says the receipt has been mailed along with instructions on the next step etc. (also from Jan 25)
My wife's GC expires on March 4.  I won't be able to do an E-request until Feb 24.
 
I'm thinking an E-request might not be a good option since the NOA probably won't arrive until after expiration.
