H-1B to Green Card: How the Employment-Based Process Works

For most H-1B holders, the H-1B is a bridge—not a destination. The end goal is an Employment Authorization Document independent of any single employer, followed by a green card and eventually citizenship. The path from H-1B to permanent resident has three mandatory sequential phases: PERM labor certification, I-140 petition approval, and I-485 adjustment of status filing. For most professionals, completing these phases takes years. For Indian nationals, the backlog extends decades.

Phase 1: PERM Labor Certification

The Program Electronic Review Management (PERM) process is the Department of Labor's mechanism for ensuring that no qualified US worker is available for the position the employer wants to permanently fill with a foreign national. The employer files PERM—not the employee.

Recruitment requirements: Before filing PERM, the employer must conduct a specific DOL-mandated recruitment campaign for the position. This typically includes:

• Two print advertisements in a newspaper of general circulation (Sunday editions, for professional positions)
• One advertisement with a job order with the State Workforce Agency for 30 days
• Three additional recruitment steps chosen from a list (job fairs, employer website posting, campus recruiting, radio advertising, etc.)

Recruitment must be completed within a specific timeframe before filing, and the employer must be prepared to document that any US applicants who applied were assessed and found unqualified for legitimate, job-related reasons.

Filing and processing: PERM is filed electronically through the DOL's FLAG system. The employer provides detailed information about the position, the wages being offered, the recruitment conducted, and the basis for any rejections of US applicants. Standard PERM processing takes approximately five to six months, though audits (which DOL may trigger for a variety of reasons) extend this significantly.

The Priority Date: The date the PERM application is submitted to the DOL becomes the beneficiary's "priority date." This date determines the beneficiary's place in the employment-based green card queue. Everything that follows depends on this date.

Phase 2: I-140 Immigrant Petition

After PERM is certified (or immediately for EB-1 and EB-2 NIW categories that do not require PERM), the employer files Form I-140, Immigrant Petition for Alien Worker, with USCIS. The I-140 is the employer's formal immigrant petition on behalf of the beneficiary.

For most H-1B holders, the relevant EB categories are:

• EB-2: Advanced degree professionals or individuals with exceptional ability. Requires either a master's degree (or bachelor's plus five years of progressive experience) or proof of exceptional ability.
• EB-3: Skilled workers with a bachelor's degree. The most commonly used category for software engineers, engineers, and other professionals without advanced degrees.
• EB-1A: Extraordinary ability (self-petition possible—no employer or PERM required). Very high evidentiary bar; requires demonstrating sustained national or international acclaim.
• EB-1B: Outstanding professors and researchers. Employer-sponsored; requires documented international recognition in the academic field.

I-140 processing under premium processing takes 15 business days. Standard processing varies. Approval of the I-140 does not grant a green card—it approves the petition, establishing the beneficiary's eligibility and confirming the priority date.

An important strategic point: if an employment relationship ends after the I-140 is approved, the approved I-140 can still be "ported" to a new employer under AC21 for a job in the same or similar occupational classification. The priority date established by the original PERM filing is preserved. This is why many H-1B holders prioritize getting the I-140 approved early, even if they are not imminently planning to file the I-485.

Phase 3: I-485 Adjustment of Status

The I-485, Application to Register Permanent Residence or Adjust Status, is the final step that converts the beneficiary's status from H-1B nonimmigrant to lawful permanent resident (green card holder). It can only be filed when the beneficiary's priority date is "current" on the Visa Bulletin—meaning a green card number is actually available for their category and country of birth.

Once the I-485 is filed, the beneficiary receives:

• An Employment Authorization Document (EAD), allowing them to work for any employer, independent of H-1B status
• Advance Parole (AP) travel authorization, allowing international travel without requiring a visa stamp for re-entry

Filing the I-485 effectively liberates the H-1B holder from dependence on employer sponsorship for work authorization. The EAD issued during I-485 pendency typically allows the beneficiary to change jobs more freely than H-1B portability.

The Visa Bulletin Crisis for Indian Nationals

The most brutal reality of the H-1B to green card path is the per-country numerical limitation on employment-based green cards. The US allocates approximately 140,000 employment-based immigrant visas per year across all EB categories. Each country can receive no more than 7% of the total in a given year—regardless of how many of those 140,000 visas are demanded by nationals of that country.

Indian nationals make up more than 70% of H-1B approvals. The per-country cap means they compete for the same 7% share as nationals of countries with essentially no backlog.

May 2026 Visa Bulletin Final Action Dates:

• India EB-2: July 15, 2014
• India EB-3: November 15, 2013
• China EB-2: September 1, 2021
• China EB-3: June 15, 2021
• All other countries EB-2 and EB-3: Current (no waiting)

A software engineer from India who filed PERM in 2020 with a priority date of early 2020 is currently looking at a Final Action Date more than six years in the past. Their I-485 cannot be filed for potentially another decade or longer.

The AC21 Extension Bridge

During the multi-decade wait, H-1B holders use AC21 extensions to remain in the US beyond the standard six-year limit. Two extension types apply:

• One-year extensions: When the PERM or I-140 has been pending for 365+ days
• Three-year extensions: When the I-140 is approved but the priority date is not current

These extensions allow the beneficiary to stay and work in H-1B status indefinitely while waiting for the I-485 to become available.

Timeline Expectations in Practice

For nationals of countries without backlogs (most of Europe, South Korea, Japan, Mexico, etc.): the process from PERM filing to green card approval typically runs 24 to 36 months, absent unusual processing delays or audits.

For Indian nationals with a 2020 priority date as of May 2026: current projections, based on the rate of Visa Bulletin advancement, suggest a wait of 15 to 25 additional years before the I-485 can be filed. These estimates are uncertain and subject to policy changes, but they reflect the current state of the queue.

For all beneficiaries: file PERM as early as the employment relationship is established and stable. Every month's delay on the PERM filing is a month later priority date—and in a system where dates move by weeks per year, early filing translates directly to meaningful queue advancement.
