What is Form I-140?
Form I-140, Immigrant Petition for Alien Worker, is filed by an employer (or self-petitioner in some categories) to classify a worker for an employment-based green card under EB-1, EB-2, or EB-3.
Approval establishes the priority date and category but does not grant status — the worker still needs a current priority date and either adjustment of status (I-485) or consular processing.
The I-140 milestone sequence
Behind each plain-English status the public site shows, USCIS records an internal event code. Here is the typical I-140 ladder and the codes that drive it:
How long does I-140 take?
Regular processing varies by service center; premium processing commits USCIS to act (a decision, a request for evidence or a notice of intent to deny) within a fixed window. National Interest Waiver (EB-2 NIW) self-petitions follow the same form but different evidence.
Common I-140 questions
Does premium processing speed up my I-140?
Premium processing commits USCIS to act within a set number of business days, and an RFE stops that clock: a new one starts when USCIS receives your response. The internal API shows exactly when the clock started and any hidden action.
What is EB-2 NIW?
A National Interest Waiver lets certain EB-2 applicants self-petition without a job offer or labor certification. It is filed on Form I-140.
