Applying for a green card through Adjustment of Status (AOS) is a major step for many people living in the United States 🇺🇸. The process centers on Form I-485, which allows certain immigrants to become lawful permanent residents without leaving the country. While the journey can be exciting, it’s also filled with important steps and common pitfalls. Understanding each stage, what’s required, and how to avoid mistakes can make the difference between a smooth process and months of delays or even denial.

Let’s walk through the entire Adjustment of Status journey, step by step, highlighting what happens at each stage, what you need to do, what to expect from USCIS, and how to avoid the most common mistakes in 2025.

Overview: What Is Adjustment of Status and Form I-485?

Adjustment of Status is the process that lets eligible people already in the United States 🇺🇸 apply for a green card without having to return to their home country. The main form used for this process is Form I-485, Application to Register Permanent Residence or Adjust Status. Filing this form with USCIS starts your green card application from inside the country.

The process involves several steps, including gathering documents, completing forms, attending a medical exam, and possibly going to an interview. Each step has its own requirements and deadlines. Missing even a small detail can cause delays or problems, so careful preparation is key.

Step 1: Confirm Your Eligibility and Priority Date

Before you start, make sure you’re eligible to file Form I-485. Eligibility depends on your immigration category, such as family-based, employment-based, asylum, or other special programs. You also need to check if your priority date is current. The priority date is your place in line for a green card, and it must be current according to the Department of State’s Visa Bulletin before you can file.

• Action:
  • Review your eligibility carefully. If you’re unsure, talk to a certified immigration attorney.
  • Check the latest Visa Bulletin to see if your priority date is current for your category.
• What to Expect:
  • If your priority date is not current, you must wait before filing. Filing too early can lead to denial or delays.

Step 2: Download the Latest Form I-485 and Instructions

USCIS updates Form I-485 from time to time. As of December 2024, a new version is required. Using an outdated form is a common mistake and will cause your application to be rejected.

• Action:
  • Always download the latest Form I-485 and its instructions directly from the official USCIS website.
  • Read the instructions fully before you start filling out the form.
• What to Expect:
  • The new form includes more questions about your immigration history and public charge issues.
  • You must submit Form I-693 (medical exam) at the same time as your I-485.

Step 3: Complete Form I-485 Carefully

Every section of Form I-485 must be filled out completely and accurately. Missing information, incorrect dates, or inconsistent details can cause delays or even rejection.

• Action:
  • Fill out every question. If something doesn’t apply, write “N/A” (not applicable).
  • Double-check all personal details, addresses, and dates for accuracy.
  • Make sure your answers are consistent with other immigration forms you’ve filed.
• What to Expect:
  • USCIS will review your form for completeness and accuracy. Mistakes can lead to Requests for Evidence (RFEs) or denials.

Step 4: Gather All Required Supporting Documents

USCIS requires specific documents to support your I-485 application. These may include:

• Birth certificate
• Passport pages showing your identity and lawful entry
• Marriage certificate (if applying as a spouse)
• Divorce decrees (if applicable)
• Proof of lawful status (such as I-94 arrival/departure record)
• Affidavit of Support (Form I-864) for most family-based applicants
• Certified English translations for any foreign-language documents

Missing even one required document is a common reason for delays.

• Action:
  • Use the USCIS checklist to make sure you have every required document.
  • Get certified translations for any documents not in English.
  • Make clear copies of all documents.
• What to Expect:
  • If something is missing, USCIS will send an RFE, which can add months to your case.

Step 5: Schedule and Complete the Medical Exam (Form I-693)

A medical exam is required for all I-485 applicants. As of 2025, you must submit Form I-693, Report of Medical Examination and Vaccination Record, at the same time as your I-485.

• Action:
  • Find a USCIS-approved civil surgeon using the USCIS doctor locator.
  • Schedule your exam and bring your vaccination records.
  • The doctor will give you a sealed envelope with Form I-693. Do not open it.
• What to Expect:
  • If you don’t submit Form I-693 with your I-485, your case will be delayed until you provide it.

Step 6: Calculate and Pay the Correct Filing Fee

Filing fees for Form I-485 vary depending on your age and category. Submitting the wrong fee or using the wrong payment method will cause your application to be returned.

• Action:
  • Check the current fee schedule on the USCIS I-485 page.
  • Pay by check, money order, or credit card as allowed. Make checks payable to “U.S. Department of Homeland Security.”
• What to Expect:
  • If your payment is wrong, USCIS will not process your application.

Step 7: Sign the Form in All Required Places

An unsigned Form I-485 is automatically rejected.

• Action:
  • Sign the form exactly where required. If someone helped you fill it out, they must sign as a preparer.
• What to Expect:
  • Unsigned forms are returned without processing.

Step 8: Make Copies and Submit Your Application

Before you send your application, make copies of everything for your records.

• Action:
  • Copy your completed Form I-485, all supporting documents, and your Form I-693.
  • Use a trackable mailing service to send your package to the correct USCIS address listed in the instructions.
• What to Expect:
  • You’ll receive a receipt notice (Form I-797C) within about 3 business days for standard cases, according to recent improvements in USCIS processing.

Step 9: Maintain Your Legal Status While Your Case Is Pending

You must keep your immigration status legal while your I-485 is being processed. Falling out of status can put your application at risk unless you qualify for certain exceptions, such as VAWA or asylum.

• Action:
  • Do not let your visa or status expire while your case is pending.
  • If you have questions about your status, consult an immigration attorney.
• What to Expect:
  • If you fall out of status, your application could be denied unless you qualify for an exception.

Step 10: Update USCIS If You Move

If you change your address while your application is pending, you must tell USCIS within 10 days.

• Action:
  • File Form AR-11 online or by mail to update your address.
• What to Expect:
  • If you don’t update your address, you might miss important notices or interview appointments, which can cause delays or denials.

Step 11: Monitor Your Case and Respond to USCIS Requests

After you file, you can track your case status online using your receipt number. USCIS may send you Requests for Evidence (RFEs) if they need more information.

• Action:
  • Check your case status regularly on the USCIS Case Status Online page.
  • Respond to any RFEs or notices quickly and completely.
• What to Expect:
  • Delays are common if you don’t respond to USCIS requests on time.

Step 12: Attend Your Biometrics Appointment and Interview

Most applicants must go to a biometrics appointment (fingerprinting) and, in many cases, an interview at a local USCIS office.

• Action:
  • Attend your biometrics appointment as scheduled.
  • Prepare for your interview by reviewing your application and bringing all original documents.
• What to Expect:
  • Missing your appointment or interview can cause your case to be denied.

Estimated Timeframes for Each Stage (2025)

• Receipt Notice: About 3 business days after filing
• Biometrics Appointment: 3–6 weeks after receipt notice
• Interview Notice: 6–12 months after filing (varies by location and case type)
• Decision:
  • Family-based cases: about 9.2 months median processing time
  • Employment-based cases: about 6.9 months median processing time

Processing times can change, so always check the latest updates on the USCIS Processing Times page.

Common Mistakes to Avoid (and How to Prevent Them)

   • Double-check every answer on your I-485 and supporting forms.
2. Missing Documents:

What to Expect from USCIS Throughout the Process

USCIS will review your application for completeness and eligibility. They may ask for more information, schedule you for biometrics and an interview, and finally make a decision on your case. If approved, you’ll receive your green card by mail. If denied, you’ll receive a letter explaining why and whether you can appeal.

Looking Ahead: Changes and Updates in 2025

USCIS continues to update its forms and processes to make things faster and reduce mistakes. In late 2025 and beyond, more changes may come, especially around public charge rules and eligibility.
