Unlike immediate relatives of U.S. citizens, who have no quota to wait for, family-preference relatives are capped every year — and demand wildly outstrips the cap. That mismatch is the entire story. The form you file (an I-130) is the easy part; the hard part is the years between filing and a visa number becoming available. Here's how the categories work, why the backlog exists, and how to read the current line yourself.
The categories
The five family-preference lanes
SettledFamily preference is divided into five categories under the immigration statute. Which one you're in depends on the sponsor's status, the relationship, and whether the relative is married or over 21:
- F1 — unmarried sons and daughters (21+) of U.S. citizens.
- F2A — spouses and minor children (under 21) of green-card holders.
- F2B — unmarried sons and daughters (21+) of green-card holders.
- F3 — married sons and daughters of U.S. citizens.
- F4 — brothers and sisters of adult (21+) U.S. citizens.
One detail that matters later: spouses and children of a preference immigrant get the same place in line as the main applicant (they can "follow to join"). So F3 and F4 are really whole-family queues, not just single-person ones.

The mechanism
Why the line exists at all
Settled structure · numbers set yearlyTwo limits create the backlog. For fiscal year 2026, the total family-sponsored preference supply is 226,000 visas, and no single country can take more than the per-country limit of 25,620. When worldwide demand or a specific country's demand runs past the available supply, a line forms and grows. In the July 2026 family chart, Mexico, India, and the Philippines show separate family-preference pressure; China-mainland sits on the worldwide family dates this month, even though China is separately familiar from the employment backlog.
Your spot in that line is your priority date: the day the I-130 was properly filed. Each month, the Visa Bulletin publishes a cutoff date per category and country; when the cutoff passes your priority date, a visa number is available and your case can move to its final step.

The bright spot
F2A is the category that actually moves
SettledIf you're a green-card holder waiting to bring a spouse or young child, the news is better than the backlog's reputation suggests. F2A gets a large, protected share of the supply: 77% of the entire second-preference allocation goes to F2A, and 75% of that is exempt from the per-country cap. That structural advantage is why F2A typically moves far better than F2B, F3, or F4 — and why a green-card holder's spouse usually waits a manageable time rather than a generational one.

The current line
Reading the July 2026 chart (and one myth it kills)
Moving · dates change monthlyHere's where the worldwide Final Action Dates sat in the July 2026 bulletin: F1 at February 2018, F2A at January 2025, F2B at November 2017, F3 at April 2012, and F4 at January 2009. Read that bottom number again — siblings filed in early 2009 are only now reaching the front of the worldwide line.
Live check: these dates change every month. Before making a timing decision, open the current State Department Visa Bulletin and USCIS's which-chart-to-use page.
The country-specific picture is sharper still:
- Mexico is the hardest overall — F3 back to June 2001, F4 to April 2001: waits measured in decades.
- The Philippines is severe in F1, F3 (Feb 2006), and F4 (Aug 2007).
- India's family lines mostly track the worldwide chart, with its one extra lag in F4 (Nov 2006).
- China — and this is the myth-killer — is not separately penalized in the July 2026 family chart; it sits on the worldwide dates across all five categories.
That last point matters because people assume China's famous employment-based backlog carries over to family cases. For family preference right now, it doesn't. (The mechanics of reading these two charts — Final Action Dates vs Dates for Filing — work the same way we walk through for the employment green card.)

How the line moves
Forward, flat, or backward — movement isn't uniform
MovingCutoff dates don't march steadily. From June to July 2026, several worldwide lines advanced — F1 jumped from September 2017 to February 2018, F4 from November 2008 to January 2009 — while India's and Mexico's F4 dates stayed frozen. A month of "movement" for some can be a flat month for others.
Dates can also go backward. If a category's demand or annual limit forces it, the State Department can retrogress a cutoff — or mark a category "unavailable" — so a date that was "almost there" slips back, with no change to your underlying petition. One procedural trap to avoid: under the statute (INA 203(g)), if the National Visa Center contacts you and you don't respond within a year, the petition can be terminated. Stay reachable, even during a long wait.
For a preference case, "how long does the paperwork take" is the wrong question. The real question is "where is my priority date in the line, and which way is the line moving."

The honest notes most guides skip
- Identify your exact category and chargeability country first. Everything about your wait flows from those two facts.
- Watch both charts every month. Final Action Dates and Dates for Filing move independently, and USCIS decides separately which one adjustment applicants may use.
- Don't assume China behaves like its employment-based backlog. In the current family chart, it sits on the worldwide dates.
- Respond to the NVC within a year of contact. Going silent can terminate a petition you waited years to advance.
What's settled vs moving
What could change
Categories fixed · cutoffs move every monthThe category definitions, the annual cap, and the per-country limit are statutory and stable — they're not what changes. What changes, every single month, are the cutoff dates, and they can advance, stall, or retrogress without warning. So treat any specific date in this article as a snapshot of the July 2026 bulletin, not a fixed fact: always open the current Visa Bulletin, and check the separate USCIS chart page that tells adjustment filers which chart to use. Check the official source, and check the date.

If you're in a preference line, remember four things
- There are five categories (F1, F2A, F2B, F3, F4) — your wait depends entirely on which one.
- The backlog is a quota problem, not a paperwork problem: your priority date is your place in line.
- F2A moves best; F3 and F4 (especially Mexico and the Philippines) can mean decades.
- Cutoffs move monthly and can retrogress — read the current bulletin, not last year's.
