Roughly 1.1 million people are stuck in the US employment-based green card backlog. Add family-sponsored applicants, and the line stretches past 4 million. For applicants from a handful of countries, the wait is not months or years. It is decades.

The numbers are not a rounding error. They represent nurses, engineers, farmworkers, and the adult children of US citizens who filed paperwork before some of today's applicants were born. Some will die before a visa number becomes available. Others will age out of eligibility entirely.

This article breaks down how the backlog works, why it keeps growing, who waits longest, and what options exist for people caught in it.

How the Green Card Backlog Actually Works

The United States caps most green cards by law. For family-sponsored preferences, the annual worldwide limit is 226,000. For employment-based preferences, it is 140,000. Those numbers have not changed since 1990, when the US population was roughly 250 million. It is now over 335 million.

On top of the worldwide caps, there is a per-country limit: no single country can receive more than 7 percent of the total visas in any category. That rule was designed to prevent one nation from dominating the queue. In practice, it means countries with enormous demand — India, China, Mexico, and the Philippines — face waits that dwarf everyone else's.

Each month, the State Department publishes the Visa Bulletin, which shows "priority dates" for each category and country. If your priority date — the day USCIS received your petition — is earlier than the cutoff listed, you can move forward. If it is later, you wait. For Indian applicants in the EB-2 category, the cutoff has at times sat more than a decade in the past.

When demand exceeds supply, the line grows faster than it shrinks. That is the core mechanic behind the backlog. It is not a processing delay. It is a queue that is mathematically designed to move slowly for certain applicants.

Who Waits the Longest — and Why

The worst waits fall on Indian nationals in employment-based categories. According to estimates from the Cato Institute, roughly 400,000 Indian applicants are in the EB-2 and EB-3 backlogs. Many of them hold advanced degrees and have been working legally in the US for years on H-1B visas. Their projected wait: anywhere from 50 to more than 130 years for some applicants, depending on category and country of birth.

Family-sponsored applicants face their own version of the problem. The F-4 category — brothers and sisters of US citizens — has a worldwide cap of just 65,000 visas per year. For applicants from Mexico, the wait for an F-4 visa has exceeded 20 years. For the Philippines, it has run past 20 as well.

Unmarried adult children of US citizens (F-1) from Mexico have waited more than 20 years. Married sons and daughters (F-3) from Mexico: similar. These are not people who filed late. Many filed in the 1990s.

The backlog also creates a hidden problem: children who "age out." A child who is a derivative beneficiary on a parent's petition loses eligibility when they turn 21. If the wait is long enough, the child is removed from the case entirely and must start over — often in a category with an even longer line. A full breakdown of how these categories stack up is available in our explainer on the green card backlog and why some applicants wait decades.

The Policy Choices That Built the Line

The 1990 Immigration Act set the current caps. Congress has not raised them since. Meanwhile, the number of people seeking permanent residency has grown steadily, driven by family ties, employer demand, and global mobility.

Two structural features make the backlog worse:

  • Unused visas are lost. If a category does not use all its visas in a fiscal year, the unused numbers do not roll over to the next year. They disappear. In some years, tens of thousands of visas have gone unused because of processing slowdowns or bureaucratic timing.
  • Per-country caps do not adjust for demand. A country with 10,000 applicants and a country with 1 million applicants get the same 7 percent ceiling. The result is a line that moves at radically different speeds for people in identical situations.

Congress has introduced bills to eliminate the per-country cap — most notably the Fairness for High-Skilled Immigrants Act, which passed the House multiple times but stalled in the Senate. Even if it passed, it would not create new visas. It would just redistribute the wait, shifting it from Indian applicants to applicants from the rest of the world.

Raising the caps is the only fix that would shorten the line for everyone. That has not happened in over three decades.

What the Backlog Does to Real People

The human cost is not abstract. Consider a software engineer from India who arrives on an H-1B at 28. Their employer files an EB-2 petition. The priority date is current at the time. Over the next decade, the cutoff retrogresses. At 40, they are still waiting. Their children, born in the US, are citizens — but the parents are not. If they change jobs, they may have to restart parts of the process. If they lose their job, they may have to leave the country.

Or consider a Filipino nurse who filed an F-4 petition for a sibling in the early 2000s. The sibling has children who were in elementary school when the petition was filed. Those children are now adults. Some have aged out. The family has been separated for two decades with no clear end in sight.

The backlog also affects US employers. Companies that rely on foreign-born workers in healthcare, technology, and agriculture face constant turnover because employees cannot get permanent status and eventually leave. Hospitals in rural areas have reported losing nurses to Canada and Australia, where permanent residency is faster.

For people in the asylum system, the wait times are a different but related problem. Our report on how the asylum process works and why wait times have grown covers that side of the system.

Practical Steps If You Are Stuck in the Backlog

There is no magic fix for the structural backlog. But there are concrete things applicants can do to protect their position and explore alternatives.

  • Lock in your priority date early. The date USCIS receives your petition is your place in line. File as soon as you are eligible. A single day can matter when cutoffs move backward.
  • Check the Visa Bulletin every month. Cutoffs can move forward or backward. Knowing where your category and country stand helps you plan. The State Department publishes it monthly, and it is free.
  • Consider whether you can "cross-charge" to a spouse's country of birth. If your spouse was born in a country with a shorter wait, you may be able to use their country for visa purposes. This is a legitimate strategy under US law and can cut years off a wait.
  • Explore EB-1 or NIW if you qualify. The EB-1 category (priority workers) and the National Interest Waiver under EB-2 have shorter or no backlogs for some applicants. If you have extraordinary ability, a advanced degree, or work in a field deemed in the national interest, this may be faster.
  • Keep your H-1B or other status valid. Do not let your underlying status lapse while waiting. Gaps can create problems later.
  • Document everything. Keep copies of every filing, receipt, and approval notice. If a visa number becomes available, you will need to move quickly.
  • Talk to an immigration attorney about your specific case. The rules are complex, and small differences in category, country of birth, and filing date change everything.
The backlog is not a processing problem. It is a policy problem. Until Congress changes the caps, the line will keep growing — and the people at the back of it will keep waiting.

What to Watch Going Forward

Two things could shift the backlog in the coming years. First, any congressional action on per-country caps or visa numbers. Second, administrative changes to how USCIS counts and allocates visas. Neither has produced a major fix so far.

In the meantime, the backlog functions as a de facto waiting list for millions of people who have followed the rules, paid the fees, and done everything the system asked. For applicants from India, Mexico, the Philippines, and China, the wait is not a phase. It is a life sentence of uncertainty.

Understanding how the queue works is the first step toward navigating it. The second is knowing which levers you can pull — and which ones only Congress can.
