For the September 2026 Visa Bulletin, the F4 Mexico Final Action date stands at April 8, 2001, and the Dates for Filing is set to April 30, 2001.

Family members waiting in this category should monitor progress closely and update their address and contact information with the NVC periodically.
Understanding the Backlog (F4 Mexico)
The Family-Sponsored Fourth Preference (F4) is for brothers and sisters of U.S. citizens. Sibling sponsorships from Mexico experience the longest wait times in the entire U.S. immigration system, often exceeding 25 to 30 years due to massive country backlogs.
Crucial Guidance:
- Child Status Protection Act (CSPA): Children of sponsored siblings can easily "age out" (exceed 21 years old) during the decades of waiting. CSPA allows you to subtract the time the I-130 petition was pending from the child's age when the priority date becomes current.
- Document Archiving: Because of the extreme wait times, births, marriages, and deaths will occur. Keep original civil documents, birth certificates, and marriage certificates updated and organized.
- Consular Processing Prep: F4 visas are almost always processed via the NVC and the U.S. Consulate in Ciudad Juárez. Ensure all contact emails with NVC are kept active over the decades.

How to Use This 12-Month Movement Data for Your Strategy
Department of State annual visa quotas replenish every October 1st. First-quarter bulletins (Oct-Jan) typically offer the widest Chart B filing windows, spring bulletins reach peak Chart A advancement, and summer months carry heightened risk of retrogression or category exhaustion.
