The employment-based green card process moves a foreign worker from a temporary visa to permanent residency through four sequential steps: a Department of Labor test showing no U.S. worker is available, an immigrant petition filed with USCIS, a wait for a visa number to become available under annual limits, and a final application for the green card itself. Federal law sorts these cases into five preference categories, and the category you fall into determines whether you need labor certification at all, how much documentation the case requires, and how long you will wait. For workers born in high-demand countries, the total timeline can stretch past a decade; for top-tier candidates in current categories, it can be under a year.
The Five Preference Categories
The Immigration and Nationality Act divides roughly 140,000 employment-based green cards each fiscal year among five tiers.1Office of the Law Revision Counsel. 8 USC 1153 – Allocation of Immigrant Visas Which one fits you drives everything downstream.
EB-1 covers priority workers: people with extraordinary ability in the sciences, arts, education, business, or athletics; outstanding professors and researchers with at least three years of experience and international recognition; and multinational managers or executives transferring to a qualifying U.S. affiliate after working abroad for the same organization. EB-1 skips labor certification entirely, and applicants with extraordinary ability can file their own petition without an employer.
EB-2 is for professionals with a master’s degree or higher, or a bachelor’s plus at least five years of progressive experience in the field (which regulations treat as equivalent to a master’s).2eCFR. 8 CFR 204.5 – Petitions for Employment-Based Immigrants It also covers people with exceptional ability whose expertise significantly exceeds what is normally encountered in the field. Most EB-2 cases require labor certification, but the National Interest Waiver offers a way around that requirement.
EB-3 is the broadest category and has three subgroups: skilled workers in jobs requiring at least two years of training or experience, professionals with a U.S. bachelor’s degree or foreign equivalent, and “other workers” filling permanent unskilled positions. The other-workers subgroup is capped at 10,000 visas per year, which produces some of the longest backlogs in the system. Every EB-3 case needs labor certification.
EB-4 covers a mixed group of special immigrants including religious workers, certain long-term employees of the U.S. government abroad, and qualifying members of the armed forces. EB-5 is the immigrant investor category, requiring capital investment in a new U.S. business that creates at least ten full-time jobs.
Step 1: Labor Certification (PERM)
For every EB-3 case and most EB-2 cases, the process begins with the Department of Labor’s PERM labor certification. The employer must prove that no qualified U.S. worker is available for the job at the offered wage.3U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 6 Part E Chapter 6 – Permanent Labor Certification
It starts with a prevailing wage determination from the National Prevailing Wage Center, which sets the minimum salary based on the job’s location, duties, and requirements. The employer then runs a mandatory recruitment campaign. For professional positions, that means a 30-day job order with the state workforce agency, advertisements in a local newspaper on two different Sundays, and three additional recruitment activities chosen from a list that includes the company’s website, job search sites, job fairs, on-campus recruiting, and trade organizations.4eCFR. 20 CFR Part 656 – Labor Certification Process for Permanent Employment in the United States All recruitment must occur within a window of no more than 180 days and no fewer than 30 days before filing.
The employer files everything on Form ETA-9089, evaluates each resume received against the job requirements, and documents why any U.S. applicants were not hired. Every recruitment record must be kept for five years from the filing date in case of a Department of Labor audit.5U.S. Department of Labor. Instructions for ETA Form 9089 – Application for Permanent Employment Certification
This is where many cases quietly die. Sloppy records, ads that don’t match the job requirements, or an inability to explain why a seemingly qualified U.S. applicant was passed over can sink a case on audit. Starting over means a new prevailing wage, new recruitment, and a new filing, which can add a year or more to the total timeline.
Step 2: The I-140 Immigrant Petition
Once the labor certification is approved (or immediately, for categories that skip PERM), the employer files Form I-140 with USCIS asking the government to classify the worker under the appropriate preference category.6U.S. Citizenship and Immigration Services. I-140, Immigrant Petition for Alien Workers
Two things need to be proven. The employer must show it can actually pay the salary listed on the labor certification, and pay it continuously until the worker gets permanent residency. Federal tax returns, audited financial statements, or annual reports are the usual proof; companies with 100 or more workers can instead submit a statement from a financial officer.2eCFR. 8 CFR 204.5 – Petitions for Employment-Based Immigrants The worker, in turn, provides diplomas, transcripts, licenses, and letters from past employers verifying specific duties and dates. Where a bachelor’s plus five years is being used as the equivalent of a master’s, those experience letters should document progressively responsible work in the relevant specialty.7U.S. Citizenship and Immigration Services. Instructions for Petition for Alien Workers
Standard I-140 adjudication takes months. Paying the $2,965 premium processing fee gets a faster decision.8U.S. Citizenship and Immigration Services. USCIS to Increase Premium Processing Fees Premium processing doesn’t accelerate anything later in the pipeline, but locking in the I-140 approval sooner matters for job portability and H-1B extensions, both discussed below.
Step 3: Priority Dates and the Wait
An approved I-140 does not mean you can immediately apply for the green card. Employment-based visas are subject to annual worldwide limits and per-country caps, and those limits create backlogs that vary dramatically by category and country of birth.
Your priority date is your place in line. For cases with a labor certification, it’s the date the Department of Labor accepted the PERM application. For cases without one, it’s the date the I-140 was filed.9U.S. Citizenship and Immigration Services. When to File Your Adjustment of Status Application for Family-Sponsored or Employment-Based Preference
The State Department publishes a Visa Bulletin each month with two charts for employment-based cases. The Final Action Dates chart shows when a visa can actually be issued. The Dates for Filing chart, when USCIS authorizes its use, shows the earliest date an applicant can submit their adjustment of status paperwork. To use either chart, your priority date must be earlier than the cutoff listed for your preference category and country of birth. A “C” means the category is current and anyone in it can file. A “U” means no visas are available.
For workers born in India or China, EB-2 and EB-3 backlogs can stretch for years or decades. Workers born in most other countries generally face shorter waits, and EB-1 is often current for all countries. Checking the bulletin each month becomes routine.
Step 4: Adjustment of Status or Consular Processing
When your priority date is current, you take the final step through one of two paths depending on where you are.
Filing Form I-485 Inside the United States
If you are already in the country on a valid visa, you file Form I-485 with USCIS to adjust status to permanent resident.10U.S. Citizenship and Immigration Services. I-485, Application to Register Permanent Residence or Adjust Status The filing fee depends on the applicant’s age and appears on the current USCIS fee schedule.11U.S. Citizenship and Immigration Services. G-1055, Fee Schedule You attend a biometrics appointment for fingerprints and photographs, and you submit an immigration medical exam on Form I-693 completed by a USCIS-designated civil surgeon. The medical form should be filed with the I-485 and remains valid only while that application is pending; a denied or withdrawn case means a new medical exam next time around.12U.S. Citizenship and Immigration Services. USCIS Changes Validity Period for Any Form I-693 Signed on or after Nov. 1, 2023 Civil surgeon fees are not regulated, so prices vary.
Filing the I-485 unlocks two interim benefits. Form I-765 gets you an Employment Authorization Document valid for any employer. Form I-131 gets you advance parole for international travel without abandoning your pending application. USCIS issues these as a combined “combo card” when both are filed together, with separate fees.13U.S. Citizenship and Immigration Services. Filing Form I-765 with Other Forms H-1B workers sometimes stay on H-1B rather than switching to the EAD, because H-1B status carries advantages if the green card case falls through.
Consular Processing From Abroad
If you are outside the United States, your case goes to the National Visa Center after I-140 approval. You file Form DS-260 through the Consular Electronic Application Center and pay a $345 immigrant visa processing fee.14U.S. Department of State. Fees for Visa Services You submit birth certificates, police clearances, and medical exam results. Once the NVC verifies the file, it forwards everything to the U.S. embassy or consulate that will interview you. Approval results in an immigrant visa stamped in your passport; you enter the United States as a permanent resident, and the physical green card arrives by mail.
The National Interest Waiver Shortcut
Workers who qualify for EB-2 can sometimes skip labor certification entirely through the National Interest Waiver, which also eliminates the job offer requirement and allows self-petitioning without any employer. USCIS uses a three-part test: the proposed work must have substantial merit and national importance, you must be well positioned to advance it, and waiving the usual requirements must, on balance, benefit the United States.15U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 6 Part F Chapter 5 – Advanced Degree or Exceptional Ability
The NIW has become popular with researchers, entrepreneurs, and STEM professionals. There’s no employer tied to the petition, so you control the process and avoid the expense and delay of PERM. The trade-off is a higher evidentiary burden. USCIS expects detailed documentation of both the importance of the work and your track record advancing it.
Family Members Included
Your spouse and unmarried children under 21 can receive green cards as derivative beneficiaries. No separate employer petition is required for them, and they take the same preference category and priority date as the primary worker.16Office of the Law Revision Counsel. 8 USC 1153 – Allocation of Immigrant Visas Each family member files their own adjustment or consular application, and each one counts against the annual visa numbers, which is one reason backlogs run as long as they do.
The main risk for families in long backlogs is a child turning 21 before the priority date becomes current, which would normally disqualify them. The Child Status Protection Act provides a formula that subtracts the time the I-140 was pending from the child’s actual age to produce a “CSPA age.” If that calculated age is under 21, the child remains eligible, provided they stay unmarried and seek permanent residency within one year of a visa becoming available.17U.S. Citizenship and Immigration Services. Child Status Protection Act (CSPA) For families in decade-long waits, running the CSPA math early can reveal whether a child is at risk of aging out.
Changing Jobs During the Process
Under a provision commonly called AC21, you can switch to a new employer after your I-485 has been pending for at least 180 days, as long as the underlying I-140 is approved and the new job is in the same or a similar occupational classification.18Office of the Law Revision Counsel. 8 USC 1154 – Procedure for Granting Immigrant Status You notify USCIS of the change by filing Supplement J to the I-485.
USCIS evaluates “same or similar” based on the totality of the circumstances. Officers compare the duties, required skills, education, and wages of both jobs, using Standard Occupational Classification codes as a starting point rather than a rigid test. Two jobs with identical codes can still fail if their actual duties differ substantially, and two jobs with different codes can qualify if the core work is comparable.19U.S. Citizenship and Immigration Services. How USCIS Determines Same or Similar Occupational Classifications for Job Portability Under AC21
If the employer withdraws the I-140 after it has been approved for at least 180 days, or after the I-485 has been pending for at least 180 days, USCIS will not revoke the approval. You keep your priority date and can use portability to complete the process with a new employer.20U.S. Citizenship and Immigration Services. Petition Filing and Processing Procedures for Form I-140, Immigrant Petition for Alien Workers Before either 180-day mark, the picture is worse: the I-140 can be revoked, the I-485 denied, and you may have to start over with a new employer.
Staying in Status While You Wait
H-1B visas normally cap at six years of total stay, which creates an obvious problem for anyone stuck in a backlog. Federal law provides two extensions. If at least 365 days have passed since your PERM labor certification was filed, the employer can request one-year H-1B extensions past the six-year limit. If your I-140 is approved but no visa number is yet available, the employer can request three-year extensions instead.21U.S. Citizenship and Immigration Services. FAQs for Individuals in H-1B Nonimmigrant Status
The three-year option is especially valuable for workers from countries with long waits. It reduces the paperwork burden of annual renewals and provides more stability. It also depends entirely on having an approved I-140, which is one more reason premium processing of that petition can be worth the cost for anyone facing a multi-year backlog.
