How employment-based green cards work
An employment-based green card gives a foreign worker lawful permanent residence based on their work, skills, or investment. Congress sets aside roughly 140,000 of these green cards each year worldwide, and that number includes the worker's spouse and children, not just the worker. The supply is divided among five preference categories, and on top of the category limits there is a per-country cap of about 7 percent, which is why applicants born in high-demand countries such as India and China wait far longer than everyone else.
Most cases move through the same basic sequence. For the categories that require it, the employer first completes PERM labor certification with the Department of Labor. Next, an immigrant petition (Form I-140) is filed with USCIS to place the worker in a category and lock in a priority date. The worker then waits until that priority date is current under the monthly visa bulletin. Finally, once a green card is available, the worker either files for adjustment of status (Form I-485) from inside the United States or goes through consular processing abroad. Some categories skip the first step, and the investor category uses a different petition, but the spine of the process, petition then wait then green card, is the same.
A few principles cut across every category. An approved I-140 is not a green card; it secures a place in line. Whether a green card is available at any given moment depends on the priority date and the per-country caps, not just on approval. And the worker normally has to keep some other lawful status, usually a nonimmigrant work visa, during what can be a very long wait.
The five preference categories
The right category depends on the worker's qualifications and, often, on whether an employer is sponsoring them. Each category below links to its own detailed guide.
EB-1, priority workers (about 28.6 percent of the total, plus spillover). This top category has three branches. EB-1A extraordinary ability is a self-petition for people at the very top of their field in the sciences, arts, education, business, or athletics, and it needs no job offer and no labor certification. EB-1B outstanding professors and researchers is for internationally recognized academics with an employer and at least three years of experience, with no labor certification. EB-1C multinational managers and executives is the green-card counterpart to the L-1A visa, for managers and executives transferred within a multinational company, also with no labor certification.
EB-2, advanced degree or exceptional ability (about 28.6 percent, plus EB-1 spillover). EB-2 is the standard category for jobs that require an advanced degree, or for people of exceptional ability. It normally requires a job offer and PERM labor certification. The major exception is the EB-2 National Interest Waiver, a self-petition that waives both the job offer and the labor certification for people whose work is in the national interest.
EB-3, skilled workers and professionals (about 28.6 percent). EB-3 covers skilled workers (jobs needing at least two years of training or experience), professionals (jobs needing a bachelor's degree), and a sub-group of other workers for unskilled positions, which has its own small annual sub-cap. EB-3 requires a job offer and PERM.
EB-4, special immigrants (about 7.1 percent). EB-4 is a catch-all fourth preference for specific groups defined by statute, including certain religious workers and special immigrant juveniles, among others.
EB-5, immigrant investors (about 7.1 percent). EB-5 is for people who invest a large amount of capital in a U.S. business that creates jobs, either directly or through a regional center. It grants a conditional green card first, and the investor later files to remove the conditions on Form I-829.
PERM labor certification and prevailing wage
The EB-2 (non-waiver) and EB-3 categories require the employer to complete PERM labor certification before filing the I-140. PERM is a test of the U.S. labor market: the employer obtains a prevailing wage determination, runs a set of required recruitment steps to look for qualified U.S. workers, and, if none are found, files the application (ETA Form 9089) with the Department of Labor. The date the application is filed becomes the worker's priority date, the timestamp that fixes their place in line. PERM is paperwork-intensive and, in 2026, the prevailing wage step alone is often taking several months, with the full cycle commonly running a year or more when there is no audit.
Two related pieces matter. The prevailing wage determination sets the minimum salary the employer must offer and pay, and it is also relevant in other contexts such as H-1B. And Schedule A is a shortcut: for a small set of pre-certified shortage occupations, currently registered nurses and physical therapists, the employer can skip the PERM recruitment process. The EB-1 categories, the National Interest Waiver, and EB-5 do not require PERM at all.
The immigrant petition (Form I-140) and keeping your place in line
Form I-140 is the immigrant petition that classifies the worker in an employment category and confirms the priority date. For most categories an employer files it; for EB-1A and the National Interest Waiver the worker self-petitions; EB-5 uses its own petition rather than the I-140. An approved I-140 establishes eligibility and the priority date, but it does not by itself confer status or a green card.
Premium processing is available for most I-140 categories, giving a faster decision for an extra fee, although the guaranteed window is longer for EB-1C and National Interest Waiver cases than for the others. The investor petition is not eligible for premium processing.
An approved I-140 also helps a worker hold their place during a long backlog. Under the American Competitiveness in the Twenty-First Century Act, an H-1B worker with an approved I-140 and a backlogged priority date can extend H-1B status in three-year increments beyond the usual six-year limit, and a worker can generally change employers in the same or a similar occupation once an adjustment application has been pending long enough. These protections are a major reason the I-140 is filed as early as possible.
Priority dates and the visa bulletin
Because demand far exceeds the annual supply, most categories have a waiting line, and the visa bulletin is how that line is managed. Each month the Department of State publishes cutoff dates by category and country of birth. A worker can move to the final green-card step only once their priority date is earlier than the relevant cutoff, which is what people mean by a date becoming current.
The bulletin has two charts, Final Action Dates and Dates for Filing, and USCIS announces each month which chart adjustment applicants may use. The per-country cap is what drives the long waits: applicants born in India and China can face waits of many years, and in some categories well over a decade, while applicants from most other countries are current or nearly so. For a worker choosing a category, the realistic wait for their country of birth is often as important as which category they technically qualify for.
The final step: adjustment of status or consular processing
When a green card is available, there are two ways to finish. A worker already in the United States files for adjustment of status on Form I-485, which lets them stay in the country, and while it is pending they can apply for a work permit and for advance parole to travel. A worker abroad, or one who chooses this route, goes through consular processing and is interviewed at a U.S. embassy or consulate.
This final step changed meaningfully in 2026. A USCIS policy memorandum now directs officers to treat adjustment of status as a discretionary, extraordinary form of relief rather than a near-automatic approval for an eligible applicant, and to weigh the availability of consular processing against adjusting inside the country. What this means for a given case, and what it does and does not change, is covered in our article on adjustment of status and USCIS discretion. The choice between adjusting and consular processing now deserves careful thought, especially because leaving the country can create its own problems for anyone who has accrued unlawful presence.
Fees and timing
Government fees (current as of mid-2026). The main USCIS fees are the Form I-140 base fee of $715, plus, for employer-filed petitions, the Asylum Program Fee of $600 (reduced to $300 for small employers and $0 for nonprofits). Optional premium processing on Form I-907 is $2,965. The adjustment-of-status application, Form I-485, is $1,440 by mail (slightly less if filed online), and a work permit and advance-parole request filed with it carry their own additional fees. The investor and PERM steps have their own separate costs. For applicants who finish abroad through consular processing, a new $250 Visa Integrity Fee enacted in 2025 will apply at visa issuance once the government begins collecting it; as of mid-2026 it is not yet being charged. These are only government fees, and professional fees are separate.
Timing. Two clocks run. The processing clock covers PERM (often a year or more), the I-140 (months, or faster with premium processing), and the I-485 (commonly many months). The backlog clock is the wait for a priority date to become current, which for some categories and countries dwarfs all the processing time combined. A realistic plan accounts for both.
Choosing a category, and what is changing in 2026
Matching yourself to a category. As a rough guide, people at the very top of their field look first at EB-1A; advanced-degree professionals whose work serves the national interest look at the National Interest Waiver; advanced-degree or skilled workers with a sponsoring employer use EB-2 or EB-3 through PERM; managers and executives moving within a multinational company use EB-1C; outstanding academics use EB-1B; and those able to make a large job-creating investment consider EB-5. Many people qualify for more than one path, and because the backlog depends on category and country, the best choice is often the one that is both achievable and fastest for that person.
What is changing in 2026. Three developments matter for anyone in this process. First, the adjustment-of-status discretion memo described above has made the final step less predictable. Second, a new wealth-based route, the Gold Card, was created in late 2025 and works through the existing employment-based framework, which limits its usefulness for applicants from already-backlogged countries; we cover it in our article on the Gold Card and Platinum Card. Third, the per-country backlogs for India and China remain severe across EB-2 and EB-3 and affect EB-1 as well. None of these changes the basic structure, but together they make early filing and careful strategy more important than ever.
