The steps USCIS did in FY 21.
1. Removed the need for I944.
2. Requested public for suggestions to improve the process.
3. Removed H4/L2 biometric need.
4. Allowed applicants who got rejection notice after January, to refile even the dates were not current.
5. Simplified the 485 application.
6. The visa bulletin dates started releasing faster than previous timelines.
7. Most of the delay/incomplete forms resulted in November visa bulletin, releasing on the last day of October
