Immigration
Definition
The process that allows certain foreign nationals already inside the United States to apply for lawful permanent residence (a green card) without leaving the country.
Adjustment of Status (AOS) is the domestic pathway to permanent residence, governed primarily by Section 245 of the Immigration and Nationality Act. Rather than traveling abroad to obtain an immigrant visa at a U.S. consulate, eligible applicants file Form I-485 with USCIS while physically present in the U.S. The process consolidates multiple applications into a single filing package, typically including the I-485 itself, an employment authorization document (EAD), and advance parole travel permission.
Eligibility hinges on several factors: the applicant must be physically present in the U.S., must have been lawfully admitted or paroled (with limited exceptions), and must have an immigrant visa number immediately available — meaning their priority date must be current in the monthly Visa Bulletin. Employment-based applicants typically need an approved I-140 petition before filing, while family-based applicants need an approved I-130. Certain grounds of inadmissibility can bar approval unless a waiver is obtained.
Processing times vary dramatically by USCIS service center and applicant category, ranging from several months to several years. During the pendency of an I-485, applicants can generally maintain their status through the EAD, which provides open-market work authorization, and advance parole, which permits international travel without abandoning the application. A biometrics appointment and an in-person interview are typically required.
The alternative pathway — consular processing — requires the applicant to leave the U.S. and attend an interview at a U.S. embassy or consulate abroad. AOS is generally preferred when available because it keeps the applicant in the U.S., grants interim work and travel authorization, and avoids the risk of being unable to return.
Adjustment of Status is one of the most consequential filings in immigration law — a denial or abandonment can leave an applicant without legal status and potentially subject to removal. The eligibility rules are riddled with exceptions, and mistakes in the filing package (incorrect fees, missing documents, improperly answered questions) can cause significant delays or denials.
For employers sponsoring workers through the EB-2 or EB-3 employment-based categories, AOS is often the final step in a multi-year process that began with PERM labor certification. Having an immigration attorney manage the I-485 package, respond to Requests for Evidence (RFEs), and prepare the applicant for their interview is essential to protecting that investment.
