Hello Everyone,
Joining the October 2022 filers:
Submitted documentation via Fedex: 10/5/2022
Credit card charged: 10/7/2022
NOA-1, 24 month extension letter received: 10/17/2022
Receipt number starts with MSC - MSC – National Benefits Center
Don't know if this the office that is processing our case or if this the generic receipt numbers, couldn't find another processing center on the letter or online for our case. Good luck to everyone.
