Adding to the positive progress...
- Applied/Paid December 11th, 2018.
- Conditionally Approved notification in system was 2/25/2019 (no email).
- First available Interview in CT was 5/26/2019 (which I gratefully accepted).
So my wait was 76 days for Conditional Approval. The government shutdown was definitely a factor.
I'm hoping to try walk-in hours.
