An immigration filing instrument identified by a designated form number used to request a benefit, relief, or administrative action. It governs the data fields, attestations, and supporting documents required to initiate processing of the requested action. It does not by itself confer status, permission, or protection and is ineffective if required signatures, fees, or evidence are missing. It structures the administrative record and determines what issues are presented for adjudication. The instrument is generally stable, though form content and instructions are updated over time.

Principle

The I-140 is the employer’s legal step to request immigrant classification under the employment‑based preference system; it must show a qualifying job offer (unless self‑petition permitted), the beneficiary’s qualifications, and the sponsor’s ability to pay the proffered wage from the priority date onward.

Demonstration

An engineering firm files an I-140 in the EB-2 category on behalf of a foreign research scientist after obtaining an approved PERM labor certification; the petition includes the approved job description, the scientist’s degrees, and the employer’s tax records demonstrating ability to pay.

Misapplication

Submitting an I-140 without a bona fide job offer, without evidence of the employer’s ability to pay, or relying on an employer’s verbal promise; filing an employer‑based petition where only self‑petition categories (like EB-1A or NIW) would permit the beneficiary to file without an employer.

Consequence

If approved, the I-140 establishes the beneficiary’s immigrant classification and priority date, enabling the beneficiary to seek visa availability and—when a visa number is current—to file Form I-485 to adjust status or pursue consular processing; it also affects derivative family members’ eligibility.

Reversal

The inverse is a denied or withdrawn I-140, which removes the filed priority date and prevents progression in the employment‑based immigrant process unless a new petition or a retained priority date applies.

Boundary

Applies to U.S. employment‑based immigrant classifications; it does not create nonimmigrant work authorization, replace labor certification where required, nor substitute for family‑based petitions; exceptions include self‑petition categories and cases where PERM is not required.

Semantic Tension

Tension exists between I-140 and PERM labor certification: PERM is an employer’s labor market test and often a prerequisite, whereas I-140 is the immigration petition that relies on PERM when required; another tension is between employer‑filed I-140s and self‑petitioned immigrant petitions.

Synthesis

Form I-140 is the legal instrument by which an employer (or qualified self‑petitioner) requests long‑term immigrant classification for a worker, combining proof of a qualifying position, the worker’s credentials, and the sponsor’s ability to pay to create an enforceable priority in the employment‑based visa system.
