The core USCIS petition that formally establishes a foreign worker's eligibility for an employment-based green card — a critical filing that sets the priority date and anchors the entire permanent residence process.
Form I-140, the Immigrant Petition for Alien Workers, is filed by an employer (or self-petitioned in certain categories) with USCIS to classify a foreign national as eligible for an employment-based immigrant visa. The I-140 is the foundational document in most employment-based green card processes: its approval establishes — or confirms — the applicant's priority date, which determines their place in the immigrant visa queue.
The I-140 is used across multiple employment-based preference categories. EB-1A (extraordinary ability) and EB-1B (outstanding researcher) petitions are self-petitioned or employer-filed and do not require a PERM labor certification. EB-1C (multinational manager or executive) requires the employer to document the qualifying relationship and managerial role. EB-2 and EB-3 petitions are almost always preceded by an approved PERM labor certification, which must be attached to the I-140 filing. EB-2 National Interest Waivers (NIW) allow self-petitioned applications without PERM.
Once approved, the I-140 serves as the permanent record of the worker's immigrant petition. Critically, an I-140 that has been approved for 180 days or more remains valid as a priority date anchor even if the sponsoring employer withdraws it — this is the AC21 portability rule, which allows workers to change jobs or employers without losing their place in the queue, provided the new position is in the same or similar occupational classification.
Premium processing (Form I-907) is available for I-140 petitions in most categories, accelerating the adjudication to 15 business days for an additional $2,805 fee (as of recent schedules). Given that the approval triggers priority date availability tracking, many employers pay for premium processing to keep timelines predictable.
The I-140 is arguably the most important filing in the employment-based green card journey. An improperly filed petition — whether due to a mismatched job description, insufficient evidence of extraordinary ability, or errors in the underlying PERM — can result in a denial that wastes years of process and potentially forces the employee to leave the U.S. Getting it right the first time is essential.
For employers retaining key international talent, early I-140 filing creates a safety net: once approved and aged 180 days, the priority date is protected even if business needs change and the employee must move to a different role or company. Immigration attorneys ensure the evidentiary package meets the adjudication standard for the specific category and respond effectively to Requests for Evidence.
