I just got a NOA in the mail from the California Service Center regarding an I-129F. It says Notice Type: Receipt Notice. The Received Date is July 9, and the Notice Date is July 13. It also has my case number on it. I thought that you get the NOA1 when they actually open your petition, not just receive it, so I'm wondering if this is the actual NOA1. Any thoughts from past filers?
Yes thats NOA1, they do send it out when your file has been opened. But now you will end up waiting about 3 months until you get your NOA2. You can use the case number on the USCIS case status site to see the status of your case.
