H-1B to Green Card: The PERM and I-140 Timeline Explained

H-1B to Green Card: The PERM and I-140 Timeline Explained

An H-1B visa is temporary by design, but for many professionals it is the first step toward permanent residency. The path from H-1B to a green card usually runs through three main stages, and understanding how they fit together helps you plan your career and your family's future with far less anxiety.

This guide walks through the typical employment-based green card process in plain language, and explains why timing matters so much — including how you may be able to stay in H-1B status beyond the usual six-year limit.

Stage One: PERM Labor Certification

Most employment-based green cards in the professional categories begin with PERM labor certification. In general terms, the employer must test the U.S. labor market — through required recruitment steps — and demonstrate to the Department of Labor that there is no qualified, willing, and available U.S. worker for the position at the offered wage.

PERM is employer-driven. It establishes a "priority date," which is essentially your place in line for a green card. That date can matter enormously, because it determines when you can move forward depending on visa availability for your category and country of birth.

Stage Two: The I-140 Immigrant Petition

Once labor certification is approved, the employer files Form I-140, the immigrant petition for a foreign worker. This petition asks USCIS to recognize that you qualify for the offered position and that the employer can pay the required wage. Approval of the I-140 is a major milestone: it confirms the underlying basis for your green card.

The I-140 also connects to your ability to keep working in the United States. In certain situations, an approved I-140 supports the extension of H-1B status past the standard limit, which is where AC21 comes in.

Stage Three: Adjustment of Status or Consular Processing

The final stage depends on whether you are inside the United States and whether a visa number is available for your category. If a visa is available and you are in the U.S., you may be able to file Form I-485 to adjust status to permanent resident. If you are abroad, you would generally complete consular processing at a U.S. consulate.

Visa availability is driven by the monthly Visa Bulletin, and for some categories and countries the wait can be long. This is exactly why the earlier stages, and your priority date, are so important.

Staying in H-1B Status Beyond Six Years: AC21

H-1B status is normally capped at six years. However, the American Competitiveness in the Twenty-First Century Act (AC21) generally allows extensions beyond six years in defined circumstances tied to a pending green card process — for example, where a labor certification or immigrant petition has been pending long enough, or where an approved I-140 exists but a visa number is not yet available. The exact rules are technical, and how they apply depends on your specific case.
