The monthly Visa Bulletin is the single most consequential document in U.S. immigration that almost no one outside the system reads carefully. It governs whether you can submit an adjustment-of-status application this month, whether NVC can schedule your consular interview, and whether your priority date is “current.” For applicants in family-preference and employment-based categories, understanding the difference between the two date charts — Final Action Dates (FAD) and Dates for Filing (DFF) — is the difference between filing on time and waiting another year.
This article complements our sibling piece on the chart structure; here we focus on the FAD-vs-DFF toggle itself and how USCIS decides which chart governs adjustment filings each month.
What changed
DFF charts were introduced in October 2015 as part of a joint DOS / USCIS modernization effort. Since then, the question of which chart governs which step has evolved each fiscal year. In 2026, the operative rules are:
- For consular processing, NVC schedules interviews based on the FAD chart only. The DFF chart does not advance an immigrant-visa case at NVC. See 9 FAM 503.1.
- For adjustment of status, USCIS announces each month — usually within a week of the Bulletin’s release — whether applicants may file under the FAD or the DFF chart. The announcement is posted at uscis.gov/visabulletininfo.
- DOS’s “use DFF” recommendation in the Bulletin itself is advisory; USCIS’s announcement is operative for adjustment cases. The two have aligned in most months since 2022.
Why it matters
The chart that governs your case determines whether your priority date is current. The FAD chart is the date on which a visa number becomes available (and an immigrant visa can actually be issued or LPR status granted). The DFF chart is the earlier date on which USCIS will accept an adjustment application (so the applicant can get employment authorization, advance parole, and start the adjustment medical clock — without waiting for the visa number to become available).
Three structural points:
- Consular cases run on FAD. If you are processing through NVC, ignore the DFF chart for scheduling purposes. NVC will not schedule your interview until your priority date is current on the FAD chart for your category and country of chargeability. See 9 FAM 503.1.
- Adjustment cases may run on either. Each month, USCIS decides. When USCIS authorizes use of DFF, an applicant whose priority date is current on DFF (but not on FAD) may file the I-485 and ancillary applications. The case will not be approved until the date is current on FAD, but the adjustment file is in.
- The retrogression risk. A category that was current can retrogress (move backward) in a subsequent Bulletin if demand exceeds supply. Filed cases retain their priority date; not-yet-filed cases do not. The DFF chart is, in practice, an anti-retrogression tool — it lets adjustment applicants secure their place in the queue.
Way forward
Practical guidance for reading the Bulletin each month:
- Identify your category and country of chargeability. Family-sponsored (F1, F2A, F2B, F3, F4) and employment-based (EB-1 through EB-5) categories each have their own column; each has a per-country column for China (mainland), India, Mexico, and the Philippines, plus an “All Chargeability Areas” column for everyone else.
- Read both charts every month. The Bulletin publishes Chart A (Final Action Dates) and Chart B (Dates for Filing). Then check USCIS’s announcement for the month — which chart applies to adjustment filings, by category.
- Track DOS’s commentary in Sections C, D, and E. The DOS Visa Office publishes monthly commentary about expected movement, demand patterns, and likely retrogression. This is the best forward-looking signal available.
- For consular cases, watch the NVC scheduling lag. Even when the FAD becomes current, NVC schedules interviews based on internal capacity and post-availability. A current priority date in May may produce an interview slot in July or August.
- For adjustment cases, file the moment DFF is current and USCIS authorizes its use. The filing locks in the priority-date queue position and triggers ancillary benefits (EAD, advance parole) that can take months to receive. Waiting for FAD to become current means leaving those benefits on the table.
A subtler point worth flagging: the relationship between DFF and FAD is asymmetric across categories. For EB-2 and EB-3 from India and China — the most backlogged categories in the system — DFF typically runs months ahead of FAD, sometimes more than a year. For F2A worldwide, the two charts have been near-identical for much of 2024–2026. For oversubscribed family categories from Mexico and the Philippines, DFF often offers a meaningful filing advantage.
The Bulletin is published in the second or third week of each month, effective the first day of the following month. Set a calendar reminder.
