The pathways and requirements for U.S. permanent residence are set by the Immigration and Nationality Act, which recognizes four main routes to a Green Card — family sponsorship, employment, humanitarian protection, and the diversity visa lottery — and layers on admissibility rules, documentation demands, and ongoing obligations that continue long after approval.1Legal Information Institute. Lawful Permanent Resident (LPR) Permanent residents can live and work in the United States indefinitely, but the status carries real duties: filing U.S. taxes on worldwide income, keeping the country as your primary home, reporting address changes, and renewing the card on time.
The Routes to a Green Card
Family-based sponsorship is the most common path. U.S. citizens can petition for spouses, unmarried children under 21, and parents as “immediate relatives,” a category with no annual cap. Other relatives, and family members sponsored by current permanent residents, fall into preference categories that are subject to yearly numerical limits and often long waits.
Employment-based immigration is divided into five preference categories, running from priority workers with extraordinary abilities (EB-1) through investors putting capital into new U.S. commercial enterprises (EB-5).2U.S. Department of State. Employment-Based Immigrant Visas Most employment routes require a job offer from a U.S. employer who files the petition. Some EB-1 applicants and EB-5 investors can self-petition.
Humanitarian pathways protect people who have faced persecution: refugee and asylee status can later convert to permanent residency. The Diversity Visa Program makes up to 50,000 immigrant visas available each year through a random lottery drawn from countries with historically low immigration to the United States.3U.S. Citizenship and Immigration Services. Green Card Through the Diversity Immigrant Visa Program Special immigrant categories cover religious workers, certain juvenile dependents, and people who have assisted the U.S. government in specific roles.
Who Is Eligible
Every applicant must clear the admissibility standards in Section 212 of the Immigration and Nationality Act.4Office of the Law Revision Counsel. 8 USC 1182 – Inadmissible Aliens Grounds that can bar a Green Card include certain criminal convictions, national security concerns, specific communicable health conditions, prior visa fraud, and past violations of immigration law. Some bars can be overcome with a waiver, though the waiver process adds time and complexity.
If you are applying from inside the United States through “adjustment of status,” you must have been inspected and admitted or paroled into the country at an official port of entry.5Office of the Law Revision Counsel. 8 USC 1255 – Adjustment of Status of Nonimmigrant to That of Person Admitted for Permanent Residence People who entered without inspection generally cannot adjust status unless they qualify for a narrow exception, such as certain VAWA self-petitioners.
The Public Charge Rule
Applicants must also show they are not likely to become primarily dependent on government cash assistance for basic needs. The government looks at whether you are likely to rely on specific cash benefits: Supplemental Security Income, cash assistance under Temporary Assistance for Needy Families, or state and local cash welfare programs. Long-term institutionalization at government expense also counts.6eCFR. 8 CFR 212.21 – Definitions
Medicaid (except for long-term institutional care), food assistance, and housing subsidies do not factor in. Simply applying for a benefit, or being approved for future benefits, does not count as “receipt.” The standard focuses on cash benefits you personally received as a named beneficiary.
Waiting for a Visa Number
Not everyone who qualifies can file immediately. Because annual visa numbers are capped in most preference categories, the Department of State publishes a monthly Visa Bulletin that controls when applicants can move forward. Each applicant gets a “priority date” when the petition is filed and can only file for adjustment of status once that date becomes current on the bulletin.7U.S. Citizenship and Immigration Services. Adjustment of Status Filing Charts from the Visa Bulletin
In oversubscribed categories, particularly for applicants from India, China, Mexico, and the Philippines, the wait can stretch years or decades. Dates can move forward from month to month or retreat (“retrogress”) depending on demand, so anyone in a preference category should check the bulletin regularly.
What to File and What to Include
The core application for adjusting status inside the United States is Form I-485. Depending on the category, you will also need a supporting petition: Form I-130 for family-based cases or Form I-140 for employment-based cases. In some situations the supporting petition and the I-485 can be filed together (concurrent filing), provided a visa number would be immediately available once the petition is approved.8U.S. Citizenship and Immigration Services. Form I-485 Instructions for Application to Register Permanent Residence or Adjust Status Always download the current edition from the USCIS site; outdated versions are rejected automatically.
Along with the forms, you will need to gather:
- Certified copies of birth certificates, marriage licenses, and divorce decrees, where applicable.
- Two identical color passport-style photos on a white or off-white background, taken recently.
- Form I-693, the Report of Immigration Medical Examination and Vaccination Record, completed by a USCIS-designated civil surgeon. The exam typically costs between $150 and $700 depending on provider and location.9U.S. Citizenship and Immigration Services. Form I-693, Report of Immigration Medical Examination and Vaccination Record10U.S. Citizenship and Immigration Services. Designated Civil Surgeons
- Complete residential addresses and employment records spanning several years.
- Financial evidence showing you can support yourself, which for most family-based cases includes an Affidavit of Support (Form I-864) from your petitioner.
Missing signatures, expired forms, or an incomplete medical exam are among the fastest ways to have a package rejected before anyone reviews the substance. Check every page before you mail.
Fees, Filing, and What Happens After
The completed package goes to a specific USCIS Lockbox or service center based on your category and where you live. For most adults over 14, the filing fee for Form I-485 is $1,440 by paper or $1,390 online.11U.S. Citizenship and Immigration Services. G-1055 Fee Schedule Fee waivers are available in limited circumstances for applicants who are exempt from the public charge ground and can show inability to pay, though recent legislation has restricted waiver eligibility for certain fees.12U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 1 Part B Chapter 4 – Fee Waivers and Fee Exemptions
Once USCIS accepts your filing, you receive Form I-797C (Notice of Action), which confirms receipt and gives you a case number you can track online.13U.S. Citizenship and Immigration Services. Form I-797C, Notice of Action Next comes a biometrics appointment at a local Application Support Center for fingerprints, a photograph, and a signature. The final step is an in-person interview at a USCIS field office. Bring originals of every document you submitted. Processing times vary by office, category, and caseload, and the entire process commonly takes several months to well over a year.
If your evidence does not establish eligibility, USCIS may issue a Request for Evidence giving up to 84 days to respond, or a more serious Notice of Intent to Deny with only 30 days. You have to submit everything asked for in a single response; partial responses are treated as requests for a final decision on what is already in the file.14U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 1 Part E Chapter 6 – Evidence
Working and Traveling While You Wait
You can apply for work authorization by filing Form I-765 under the (c)(9) eligibility category, either at the same time as your I-485 or later by submitting a copy of your I-485 receipt notice.15U.S. Citizenship and Immigration Services. I-765, Application for Employment Authorization Once approved, an Employment Authorization Document lets you work for any U.S. employer while you wait.
Travel needs more care. If you leave the United States while your I-485 is pending without first obtaining an advance parole document through Form I-131, USCIS will generally treat your departure as abandonment of the entire application.16U.S. Citizenship and Immigration Services. While Your Green Card Application Is Pending with USCIS This is one of the most common and most painful mistakes applicants make. Plan any necessary international trip well in advance, and get advance parole approved before you book.
Conditional Green Cards
Not every Green Card lasts ten years from the start. If you obtained permanent residency through a marriage that was less than two years old when your status was approved, you receive a conditional card valid for only two years. The same applies to EB-5 investors.17U.S. Citizenship and Immigration Services. When to File Your Petition to Remove Conditions18U.S. Citizenship and Immigration Services. I-829, Petition by Investor to Remove Conditions on Permanent Resident Status
To keep the status, file a petition to remove conditions during the 90-day window immediately before the conditional card expires. Marriage-based residents file Form I-751, normally jointly with the petitioning spouse.19U.S. Citizenship and Immigration Services. Form I-751 Instructions for Petition to Remove Conditions on Residence EB-5 investors file Form I-829 during the same window. If your marriage ended through death, divorce, or abuse before joint filing, you can still file I-751 on your own with a waiver of the joint filing requirement, as long as you entered the marriage in good faith. Missing the window has severe consequences: permanent resident status automatically terminates and you become removable from the United States. Late filings are excused only for good cause and extenuating circumstances.
Keeping Your Status
A Green Card is not a set-it-and-forget-it document. Break the ongoing rules and you can lose the status you worked to get.
Residency and Travel
Keep your primary home in the United States. Spending more than six months outside the country in a single trip creates a presumption that you have broken continuous residence; an absence of one year or more automatically breaks it.20U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 12 Part D Chapter 3 – Continuous Residence If you know you will be abroad for more than a year, apply for a reentry permit (Form I-131) before you leave. A reentry permit is typically valid for two years and prevents USCIS from treating your absence alone as abandonment.21U.S. Citizenship and Immigration Services. Instructions for Form I-131, Application for Travel Documents If you have already spent more than four of the last five years outside the country, the permit will be limited to one year. Reentry permits cannot be extended. Even with a permit, frequent or prolonged absences can still be used as evidence of abandonment.
Carrying Your Card and Reporting Address Changes
Federal law requires every permanent resident age 18 and older to carry the Green Card at all times. Failure is a misdemeanor punishable by a fine of up to $100, up to 30 days in jail, or both.22Office of the Law Revision Counsel. 8 USC 1304 – Forms for Registration and Fingerprinting Enforcement is rare, but the requirement matters during travel or any encounter with immigration officials.
Whenever you move, report the new address to USCIS within 10 days using Form AR-11, submitted online or by mail.23U.S. Citizenship and Immigration Services. How to Change Your Address The requirement applies to all non-citizens in the United States with narrow exceptions for certain diplomatic visa holders.24U.S. Citizenship and Immigration Services. AR-11, Aliens Change of Address Card
Taxes, Selective Service, and Voting
Permanent residents owe the same federal income taxes as citizens. You have to file a U.S. return and report worldwide income regardless of where you live or where the income is earned, and this obligation continues until you formally surrender the Green Card by filing Form I-407 with USCIS.25Internal Revenue Service. Frequently Asked Questions About International Individual Tax Matters If you are also a tax resident of a country with an income tax treaty with the United States, you may claim treaty benefits, but you must disclose that by attaching Form 8833 to your return.
Male permanent residents between 18 and 25 must register with the Selective Service System within 30 days of their 18th birthday, or within 30 days of entering the United States, whichever is later.26Selective Service System. Who Needs to Register Missing registration can raise good-moral-character questions when you later apply for citizenship.
Permanent residents cannot vote in federal elections. Casting a ballot in a presidential or congressional race as a non-citizen is a federal crime punishable by a fine, up to one year in prison, or both.27Office of the Law Revision Counsel. 18 USC 611 – Voting by Aliens
Renewing the Card and Moving to Citizenship
A standard Green Card is valid for 10 years. Before it expires, file Form I-90 to replace it, either online through a USCIS account or by mail.28U.S. Citizenship and Immigration Services. I-90, Application to Replace Permanent Resident Card (Green Card) Your permanent resident status does not expire when the card does, but an expired card creates practical trouble for employment verification, travel, and proving identity. Do not use Form I-90 for a conditional card that needs conditions removed; that requires Form I-751 or I-829.
Permanent residency is often a stepping stone to citizenship. The standard rules: at least five years of continuous residence as a permanent resident, physical presence for at least half of that time (30 months), and at least three months in the state where you file.29Office of the Law Revision Counsel. 8 USC 1427 – Requirements of Naturalization You must also show good moral character and pass English and civics tests. Spouses of U.S. citizens may qualify for a shorter three-year continuous residence requirement, while the same physical presence and moral character standards apply. Long absences during the statutory period can reset the clock, so anyone planning to naturalize should be especially careful about time spent abroad.
