AOS (Adjustment of Status): what it is

Two routes after petition approval. AOS - when you are already in the US in status: no embassy trip, and for the wait you can get an EAD (work for any employer) and Advance Parole (travel), but you cannot travel freely without parole, and timing depends on USCIS workload. The consular route - when you are abroad: the NVC, Form DS-260, a panel-physician medical and an immigrant-visa interview; no need to be in the US, but you depend on slots and administrative processing may follow the interview. There is no single answer on which is faster - both timelines shift.

Who can file. You need a lawful entry and a valid status at filing: "to change status you must have one", as the community puts it - parole is not a status. Entering on a B1/B2 with a ready-made intent to stay and filing soon after is the main risk, which can be treated as misrepresentation. An approved I-140 by itself grants no status and does not extend your stay: until the date is current you need a valid nonimmigrant status.

When you can file. Only when the priority date is available in the Visa Bulletin - and under the chart USCIS accepts that month (Final Action Dates or Dates for Filing, announced on the filing charts page). Early filing under Dates for Filing gives you the EAD and Advance Parole while the Final Action Date catches up with yours, and protects the filed application from a rollback: under retrogression the I-485 is not denied but put on hold until the date returns. If the category is current, EB-1A and NIW allow concurrent filing - the I-140 and I-485 together.

What happens after filing. Biometrics by USCIS appointment, sometimes an interview, then the decision; the I-693 (a civil surgeon medical), the I-765 and the I-131 go in with the I-485 - all family members in one packet. A pending I-485 gives a period of authorized stay but not a status of its own, so many keep their O-1 or H-1B in parallel. By community observations the median I-485 review is 9-13 months with a spread from 3 to 18.

Discretion and typical mistakes. AOS is a discretionary officer decision: under USCIS memo PM-602-0199 of May 21, 2026, flawlessly maintained status keeps you eligible but does not by itself earn the grant; for EB-1A and EB-2 NIW lawyers advise attaching the evidence of the importance of your work a second time - as positive factors. Common mistakes: filing "just in case" without understanding your status and date, filing under the wrong chart (a return or a denial with the fee lost), leaving without Advance Parole, showing active work without an EAD on a tax return.
