Why Do India, Mexico, and the Philippines Have the Longest Family-Based Visa Backlogs?
By Pinal Dave | Last updated: 2026-08-02
TL;DR: Family-based green cards are capped both by category and, separately, by a per-country limit that caps any single country at roughly the same small share of the annual worldwide total, regardless of how many people from that country are actually waiting. Because India, Mexico, and the Philippines send disproportionately more family-sponsored applicants than most other countries, their per-country allocation fills up far faster, pushing their priority dates years — sometimes decades — behind other countries in the same preference category.
The Claim
The wait time for a family-based green card depends heavily on which country you were born in, not just which preference category you're in — and that's a direct, structural consequence of the per-country cap built into US immigration law, not a case-by-case processing delay.
The Evidence
Family-based immigrant visas are limited by category (F1, F2A, F2B, F3, F4) and, layered on top of that, by INA §202's per-country limit, which generally caps immigrant visas to natives of any single country at around 7% of the total annual family-sponsored and employment-based visas combined. Because demand from India, Mexico, and the Philippines has historically and consistently exceeded that per-country share within several family preference categories, applicants born in those countries face separate, later "final action dates" on the monthly Visa Bulletin than applicants born elsewhere in the same category. This is why you'll often see four different dates listed for the same preference category on the Visa Bulletin: one for most of the world, and separate, later dates for China, India, Mexico, and the Philippines specifically.
Comparison: Why the Backlog Differs by Country
| Factor | Effect on Backlog |
|---|---|
| High volume of petitions filed for natives of a country | Fills that country's per-country cap faster within a category |
| Same per-country cap percentage applies regardless of population | Countries with large diasporas filing petitions (India, Mexico, Philippines, historically China) hit the cap sooner |
| Preference category itself (F1 vs F2A vs F3 vs F4) | Some categories (like F4, siblings of US citizens) have smaller annual allocations and longer waits industry-wide, compounded further for backlogged countries |
| "Rest of world" applicants in the same category | Often see current or much closer dates, since they aren't competing against the same oversubscribed per-country pool |
Step-by-Step: How to Track Your Actual Wait
- Find your exact preference category (F1, F2A, F2B, F3, or F4) based on your relationship to the petitioner.
- Check your country of birth, not citizenship or where you currently live — per-country limits are based on birth country in most cases.
- Read the Visa Bulletin's chart for your specific category and country — the "Dates for Filing" and "Final Action Dates" columns will show separate rows for China, India, Mexico, Philippines, and "All Other Chargeability Areas."
- Compare your priority date (from your I-130 receipt/approval) to the relevant listed date for your category and country each month.
- Understand that movement isn't linear. Backlogged categories and countries can move slowly, stay flat, or occasionally retrogress (move backward) depending on annual visa availability and demand that year.
Why This Structural Reality Matters
Because the per-country cap applies as a flat percentage rather than scaling with each country's population or historical migration patterns, high-demand countries like India, Mexico, and the Philippines experience backlogs that can span years or decades in certain family categories — a reality that has nothing to do with an individual case being handled slower and everything to do with the annual numerical limits set by Congress. Understanding this distinction helps set realistic expectations rather than assuming a personal processing delay.
FAQ
Does the per-country cap mean my case is being processed slower than others? No. It reflects a numerical limit on how many family-based visas can go to natives of any single country each year, not the speed of USCIS or State Department processing of your individual case.
Is the per-country limit based on my citizenship or my country of birth? Generally your country of birth, not your current citizenship or residence, with limited exceptions (such as certain cross-chargeability rules for spouses).
Can backlogged priority dates ever move backward (retrogress)? Yes. Visa Bulletin dates can retrogress when demand in a category exceeds the annual numbers available that fiscal year, even after moving forward in prior months.
Why do some categories show a current date for most countries but a much older date for India, Mexico, China, or the Philippines? Because those countries' demand in that specific category has historically exceeded their per-country share, so their applicants queue behind a longer backlog while "rest of world" applicants in the same category may face little or no wait.
