The USCIS immigration process runs through four basic stages: figuring out which category you qualify under, gathering documents and filing the right forms with the correct fees, completing biometrics and usually an interview, and receiving a written decision you can challenge if it goes against you. U.S. Citizenship and Immigration Services is the Department of Homeland Security agency that handles nearly every application for lawful status, from family green cards to asylum to work permits.1Department of Homeland Security. Operational and Support Components Filing correctly the first time matters more than most people realize. A rejection costs you the fee and months of your life; a denial can trigger consequences that make future applications harder.
Which Category You File Under
Every application starts with a category. The Immigration and Nationality Act sorts benefits into three broad pathways: family-based, employment-based, and humanitarian.2U.S. Citizenship and Immigration Services. Immigration and Nationality Act
Family-Based
U.S. citizens and lawful permanent residents can sponsor certain relatives. Federal law separates these into two groups. Immediate relatives of U.S. citizens (spouses, unmarried children under 21, and parents of citizens who are at least 21) have no annual cap on visa numbers, so there’s no numerical backlog.3Office of the Law Revision Counsel. 8 USC 1151 – Worldwide Level of Immigration Immediate relatives can also file the petition (Form I-130) and the green card application (Form I-485) together, called concurrent filing, which can shorten the wait considerably.4U.S. Citizenship and Immigration Services. Concurrent Filing of Form I-485
Everyone else falls into numerically limited preference categories: unmarried adult children of citizens (first), spouses and children of permanent residents (second), married adult children of citizens (third), and siblings of adult citizens (fourth).5Office of the Law Revision Counsel. 8 USC 1153 – Allocation of Immigrant Visas Waits run from a few years to well over a decade depending on the category and the applicant’s country of birth.
Employment-Based
Employment green cards are organized into five preference levels. EB-1 covers people with extraordinary ability, outstanding professors and researchers, and multinational managers. EB-2 is for professionals with advanced degrees or exceptional ability. EB-3 covers skilled workers and professionals. EB-4 is for certain special immigrants including religious workers. EB-5 is for investors who commit substantial capital to a U.S. business that creates jobs.5Office of the Law Revision Counsel. 8 USC 1153 – Allocation of Immigrant Visas Most EB-2 and EB-3 cases require the employer to first obtain a labor certification from the Department of Labor showing no qualified U.S. workers are available. EB-1A applicants and EB-2 national interest waiver applicants can self-petition without an employer sponsor.
Humanitarian
Asylum and refugee status both require a well-founded fear of persecution based on race, religion, nationality, membership in a particular social group, or political opinion. The difference is location: asylum is for people already in the United States, refugee status for those applying from outside.6Office of the Law Revision Counsel. 8 USC 1158 – Asylum7Office of the Law Revision Counsel. 8 USC 1157 – Annual Admission of Refugees
Asylum has a hard deadline: you must file within one year of arriving in the United States. Miss it and you lose eligibility unless you can show changed circumstances affecting your claim or extraordinary circumstances explaining the delay.8Office of the Law Revision Counsel. 8 USC 1158 – Asylum Unaccompanied minors are exempt. For everyone else, this technicality destroys otherwise valid claims.
What Can Disqualify You Even If You Fit a Category
Fitting a category isn’t enough. USCIS can still deny your case on grounds of inadmissibility, which include health issues, criminal history, security concerns, likelihood of becoming a public charge, and prior immigration violations.9Office of the Law Revision Counsel. 8 USC 1182 – Inadmissible Aliens
The public charge ground applies when an applicant appears likely to become primarily dependent on government cash assistance. USCIS uses a totality-of-the-circumstances test weighing age, health, family size, assets, income, education, and skills.10U.S. Citizenship and Immigration Services. Public Charge Inadmissibility Policy Manual For family-based cases, the Affidavit of Support (Form I-864) is the main tool for overcoming it, because the sponsor legally guarantees financial responsibility.
The unlawful presence bars deserve special attention. If you’ve been in the U.S. without legal status for more than 180 days but less than a year and then leave, you’re barred from returning for three years. Unlawful presence of a year or more triggers a ten-year bar once you depart.11Office of the Law Revision Counsel. 8 USC 1182 – Inadmissible Aliens The bars only activate when you leave. That creates a trap: someone with an overstayed visa who travels abroad for consular processing can lock themselves out of the country for years. Waivers exist in some situations but are discretionary.
Documents to Gather Before You File
Missing or improperly prepared documents are the single biggest reason applications stall or get rejected. Start early.
Every applicant needs a valid passport and a certified birth certificate. Any document not in English requires a complete certified translation along with the original. Family-based petitioners also need marriage certificates and any divorce decrees from prior marriages. Employment-based applicants typically need educational credentials, professional licenses, and letters from current or former employers.
Financial documentation is essential for family cases. The sponsor files Form I-864 and must show household income of at least 125% of the Federal Poverty Guidelines.12U.S. Citizenship and Immigration Services. I-864P, HHS Poverty Guidelines for Affidavit of Support Expect to provide federal tax returns, W-2s, and proof of current employment such as recent pay stubs or an employer letter. If the primary sponsor’s income falls short, a joint sponsor with sufficient income can file a separate I-864.
Adjustment-of-status applicants must complete a medical examination with a physician USCIS has designated as a civil surgeon. Results are documented on Form I-693 and must be submitted in the sealed envelope the doctor provides. Opening the envelope invalidates the exam.13U.S. Citizenship and Immigration Services. I-693, Report of Immigration Medical Examination and Vaccination Record USCIS does not set civil surgeon fees, so costs vary widely by location and vaccination needs.
If you’ve previously been in the U.S., include your I-94 arrival/departure record. If USCIS ever assigned you an alien registration number, put it on every form. And check every form against the current version date on the USCIS website. Outdated form editions get rejected.
How to File and What It Costs
Form I-130 (the petition establishing the qualifying relationship) and Form I-485 (the green card application itself) can be mailed to a USCIS Lockbox facility.14U.S. Citizenship and Immigration Services. Form I-130, Petition for Alien Relative15U.S. Citizenship and Immigration Services. Form I-485, Application to Register Permanent Residence or Adjust Status The correct mailing address depends on the form and your state, so check the filing instructions each time rather than reusing a previous address. USCIS also offers online filing for some applications, which lets you upload documents digitally and track case status in real time.
Immediate relatives of U.S. citizens can mail the I-130 and I-485 together in one package with all supporting documents and fees. For preference category cases, you generally cannot file the I-485 until a visa number is available, which may be years after the I-130 is approved.
Filing fees must be exact. The wrong amount gets the entire package rejected without review. As of the most recent fee schedule, Form I-130 costs $625 online or $675 by paper. Form I-485 costs $1,390 online or $1,440 by mail for applicants age 14 and older.16U.S. Citizenship and Immigration Services. Form G-1055 – Fee Schedule USCIS updated its fee schedule in May 2026, so verify current amounts at uscis.gov/g-1055 before filing. You can pay by money order, cashier’s check, or credit card (using Form G-1450).
If you can’t afford the fees, Form I-912 requests a fee waiver. You may qualify if you receive a means-tested government benefit like Medicaid, SNAP, or SSI; if your household income is at or below 150% of the Federal Poverty Guidelines; or if you’re experiencing financial hardship from a medical emergency, job loss, or similar circumstances.17U.S. Citizenship and Immigration Services. Instructions for Request for Fee Waiver, Form I-912 Not every form type qualifies for a waiver, so check the I-912 instructions.
Certain employment-based petitions and some work authorization applications qualify for premium processing through Form I-907, which guarantees USCIS action within a set timeframe. Premium processing fees effective March 1, 2026 range from $1,780 (H-2B petitions, R-1 petitions, and EAD applications) to $2,965 (most employment-based green card petitions, H-1B, L-1, and O and P visa petitions).18Federal Register. Adjustment to Premium Processing Fees Premium processing is not available for family-based petitions or the I-485 itself, which is where the longest waits typically occur. It also doesn’t guarantee approval, only a faster decision.
What Happens After You File
Once USCIS accepts your package and processes your payment, you’ll receive Form I-797C (Notice of Action) in the mail. This is your proof the case exists in the system, and it carries a 13-character receipt number you’ll use to check status online.19U.S. Citizenship and Immigration Services. Form I-797C, Notice of Action Keep it. You’ll reference the receipt number constantly, and you’ll need it for any related applications like a work permit or travel document.
A separate notice will schedule your biometrics appointment at a local Application Support Center.20U.S. Citizenship and Immigration Services. Preparing for Your Biometric Services Appointment Technicians capture your fingerprints, photograph, and digital signature for background checks. Bring valid government-issued photo ID. The appointment takes about 20 minutes; missing it without rescheduling can delay your case significantly.
Most adjustment-of-status applicants are then called for an in-person interview at a USCIS field office. An immigration officer places you under oath, asks questions about your background and eligibility, and examines original supporting documents. Marriage-based cases include pointed questions designed to test whether the relationship is genuine: how you met, details of daily life together, knowledge of each other’s families and habits. Interviews typically run 20 to 60 minutes. The officer may approve on the spot or say the case needs additional review. Either way, USCIS sends a written decision to the address on file. Approved green cards usually arrive in the mail within a few weeks of the approval notice.
Processing times vary sharply by form type and category. As of early fiscal year 2026, the median processing time for a family-based I-485 is roughly 5.5 months, while the I-130 for an immediate relative takes about 12.9 months.21U.S. Citizenship and Immigration Services. Historic Processing Times Preference categories with visa backlogs can stretch the full timeline over several years. USCIS updates published processing times regularly, and checking them is the only reliable way to gauge where your case stands.
Working and Traveling While Your Case Is Pending
Filing a green card application doesn’t automatically give you the right to work or travel. If your I-485 is pending, you can apply for an Employment Authorization Document (EAD) using Form I-765 under category (c)(9), either together with the I-485 or at any point while the adjustment application is pending.22U.S. Citizenship and Immigration Services. Form I-765, Instructions for Application for Employment Authorization
Travel is where cases die. If you leave the United States while your I-485 is pending without first obtaining an advance parole document (Form I-131), USCIS will generally treat your green card application as abandoned.23U.S. Citizenship and Immigration Services. Instructions for Form I-131, Application for Travel Documents Narrow exceptions exist for people in H-1, H-4, L-1, L-2, K-3, K-4, or V status who can reenter on a valid visa in that classification. For everyone else, leaving without advance parole effectively kills the pending application. This is one of the most common and avoidable mistakes in the process.
Conditional Green Cards Through Marriage
If you received your green card through marriage and were married less than two years when it was approved, your residency is conditional. It expires after two years. You must file Form I-751 to remove the conditions during the 90-day window immediately before the card expires. Filing too early gets the petition rejected; filing too late means you’ve fallen out of status.24U.S. Citizenship and Immigration Services. I-751, Petition to Remove Conditions on Residence
The standard route is a joint filing with your spouse, supported by evidence the marriage is genuine: joint bank statements, shared lease or mortgage documents, insurance policies, photos, and similar proof of a life built together. If you’re no longer married because of divorce, your spouse’s death, or domestic abuse, you can request a waiver of the joint filing requirement. The waiver petition can be filed any time before conditional status expires and requires evidence specific to the situation, such as a final divorce decree or documentation of abuse.
If USCIS Denies Your Case
A denial doesn’t always end things. USCIS offers three formal options, all filed on Form I-290B: an appeal, a motion to reopen, or a motion to reconsider.
Deadlines are tight. For most denials you have 30 days from the date USCIS personally served the decision, or 33 days if it was mailed. For revocation of an approved immigrant petition, the window shrinks to 15 days (or 18 if mailed).25U.S. Citizenship and Immigration Services. AAO Practice Manual – Chapter 3 Appeals The filing date is when USCIS receives the motion, not the postmark date. Mailing on day 32 doesn’t work.
A motion to reopen is for new evidence not part of the original record. A motion to reconsider argues USCIS applied the law or its own policy incorrectly based on evidence already in the file.26eCFR. 8 CFR 103.5 – Reopening or Reconsideration An appeal goes to the Administrative Appeals Office, which reviews the case fresh.
Which option fits depends on why USCIS denied. If the denial came from thin documentation and you now have better evidence, a motion to reopen is the right tool. If you believe the officer misread the regulation or ignored binding precedent, a motion to reconsider fits better. Appeals are broader and suit cases where you think the entire analysis was flawed. In every case, the I-290B filing fee must accompany the motion, and current amounts should be verified on the USCIS fee schedule before filing.
Staying Compliant While You Wait
Cases can take months or years, and your obligations don’t pause. If you move, federal law requires you to notify USCIS within 10 days by filing Form AR-11.27U.S. Citizenship and Immigration Services. AR-11, Alien’s Change of Address Card Skip this step and interview notices, biometrics appointments, and decision letters go to the wrong place. People have had applications denied for abandonment because they never received a request for evidence mailed to an old address.
If you hold a nonimmigrant visa while the green card application pends, maintain that status. Don’t let work authorization lapse if you’re employed. Don’t overstay a visa deadline without understanding how it affects your case. Any new arrest or criminal charge must be disclosed to USCIS. Concealing one is far worse than the underlying issue in most situations, because the agency treats candor as seriously as the facts themselves. A hidden misdemeanor can damage a case more than an honestly reported one.
