I got my text with regards to i-751 receipt - We're in Texas but somehow got MSC - Not great news with regards to processing times.
It was sent on May 26th so not too bad of a wait to hear.
My GC was due to expire today, a question from that, now that I have an MSC number does it mean the I-751 wasn't rejected and I can breath a sigh of relief for now that I won't have to re-submit after it's expired?
