What is the difference between 'Final Action Dates' and 'Dates for Filing' in the Visa Bulletin?

The U.S. Department of State releases the Visa Bulletin monthly to indicate when immigrant visa applicants can move forward with their applications. It features two primary charts: 'Final Action Dates' and 'Dates for Filing' (for family-sponsored and employment-based categories).

Final Action Dates: This chart indicates when a visa number is actually available for an applicant. If your priority date is earlier than the date listed for your category and country of chargeability, you may be approved for permanent residency. If you are in the U.S. and adjusting status, your I-485 can be adjudicated once your priority date is current according to this chart.

Dates for Filing: This chart is used by USCIS to determine if an applicant can submit their I-485 Adjustment of Status application. Sometimes, the 'Dates for Filing' are more advanced than the 'Final Action Dates.' USCIS will announce on their website each month whether they will accept applications based on this chart. If they do, it allows applicants to submit their paperwork earlier than they would otherwise be able to. This is beneficial because it allows applicants to file for work authorization (EAD) and travel documents (Advance Parole) while waiting for their priority date to become current under the Final Action chart. Always check the official USCIS 'Adjustment of Status Filing Charts' webpage before relying on the Department of State's bulletin.
