We had just got our case approved! We didn't do anything else other than just waiting since we're receiving our NOA1.
We're now waiting for the physical paper of NOA2 received in our mailbox and the the next step after that.
For everyone who're still waiting for their NOA2, don't give up! I know that there should be < 50 cases left for people who received their NOA1 in this thread as of today if the data in trackmyvisanow is accurate
