Hey to all fellow April filers! My wife and I were a bit late with filing — her GC expires next week! But fortunately there were no mistakes with the application and she now has an extension letter in hand.
Timeline:
4/24: Form I-751 delivered to Phoenix Lockbox
4/27: Credit card charged (late afternoon PST)
5/5: I-797 Notice of Action receipt delivered
5/8: Biometrics re-use and online account letters delivered
The receipt, biometrics, and online account letters all had 5/02 issue dates.
Never received text updates despite including a number so we were a little nervous we had made a mistake with the form until the card charge notifications came through.
