An Overview of Family-Based Green Cards

Family is the most common reason people receive green cards in the United States. Under the family-based system, a U.S. citizen or lawful permanent resident can petition for certain relatives to live in the country permanently. The petitioner files, the relative waits their turn if there’s a line, and the government decides whether the relationship is real and the applicant is admissible.

The system splits relatives into two groups, and the difference shapes everything that follows. Immediate relatives of U.S. citizens face no annual cap, so their cases move as fast as the paperwork does. Everyone else falls into a preference category with limited numbers, which can mean waiting for years.

Who Can Petition?

The petitioner must be either a U.S. citizen or a lawful permanent resident, and the relationship determines who can be sponsored.

  • U.S. citizens can petition for spouses, underage and adult children, parents, and siblings. To petition for a parent or sibling, the citizen must be at least 21

  • Green card holders can petition for spouses, underage children, and unmarried adult children, but not for parents, siblings, or married adult children

Relatives outside these categories, such as grandparents, aunts, uncles, and cousins, cannot be sponsored.

The Categories, Explained

Every family-based case falls into one of the following groups.

  • Immediate Relatives

    Spouses, unmarried children under 21, and parents of U.S. citizens. These cases are not subject to annual limits, so there’s no priority date and no Visa Bulletin wait.

  • F1

    Unmarried adult children of U.S. citizens.

  • F2A

    Spouses and unmarried children under 21 of green card holders.

  • F2B

    Unmarried adult children of green card holders.

  • F3

    Married children of U.S. citizens.

  • F4

    Siblings of adult U.S. citizens.

Preference categories are capped each year, and no single country can take more than a set share of the numbers. That’s why applicants from countries with heavy demand often wait much longer. Each applicant receives a priority date, generally the day USCIS receives the petition, and can move forward only once that date becomes current in the State Department’s monthly Visa Bulletin.

Two Ways to Get the Green Card

  • Adjustment of Status

    Eligible applicants who are already in the United States can apply without leaving the country by filing Form I-485 with USCIS. In general, they must have been inspected and admitted or paroled, and immediate relatives can often file at the same time as the petition.

  • Consular Processing

    Applicants abroad, and some inside the country who cannot adjust, finish the process through the National Visa Center and a U.S. embassy or consulate.

The Financial Side of the Case

Nearly every family-based applicant needs an Affidavit of Support (Form I-864), a legally binding promise from the petitioner to support the relative financially. Petitioners generally must show income at or above 125 percent of the federal poverty guidelines for their household size, though a lower threshold applies to some military petitioners. If the petitioner falls short, a joint sponsor can fill the gap. Officers also consider whether the applicant is likely to depend on public benefits, an area of the law that has been changing quickly.

Recent Changes to Watch

Consular interviews have been disrupted by country-specific restrictions and a pause on interview scheduling while consular officers train on new screening guidance. Separately, USCIS has adopted a new public charge policy that applies to adjustment applications filed on or after September 18, 2026, and it can take a wider range of public benefits into account. Some of these measures are being challenged in court and could change quickly, so it’s worth confirming the current rules before filing or traveling.

What Are the Advantages of Family-Based Green Cards?

  • Immediate Relatives Skip the Line

    Spouses, parents, and children of U.S. citizens don’t wait for a visa number, so their cases can move as soon as the paperwork is approved.

  • Permanent Life in the United States

    Green card holders can live and work anywhere in the country, and in most cases can later apply for citizenship after a set period.

  • No Job or Special Skills Required

    Eligibility comes from the familial relationship, not from a job offer, a degree, or a record of professional achievement.

How to Apply

Every case begins with a petition, so start by collecting the core documents:

  • Proof of the petitioner’s status, such as a U.S. passport, birth certificate, naturalization certificate, or green card

  • The relative’s passport and birth certificate

  • Proof of the relationship, such as a marriage certificate for spouses or birth certificates for parents and children

  • Proof that any prior marriages ended, such as divorce decrees or death certificates

  • Passport-style photographs, where required

For marriage-based cases, add evidence that the marriage is genuine, such as:

  • Joint leases, mortgages, or utility bills

  • Joint bank accounts, insurance policies, or tax returns

  • Photographs of the couple together over time

  • Travel records and correspondence

  • Statements from friends and family who know the couple

The filing itself also requires:

  • Form I-130, Petition for Alien Relative

  • Form I-485 for adjustment of status, or the immigrant visa application for consular processing

  • Form I-864 Affidavit of Support, with tax returns and proof of income

  • A medical examination by an approved physician

  • Police certificates, where required

  • All applicable filing fees

Common Pitfalls to Avoid

  • Thin Proof of a Real Relationship

    Officers look closely, especially in marriage cases. Evidence that spans years and comes from many sources is far more persuasive than a handful of photos.

  • Misjudging the Wait

    Immediate relatives can move quickly, but preference categories can take years. Check the Visa Bulletin before planning around a timeline.

  • Leaving the Country Too Soon

    Departing the United States can trigger bars on returning for people who have built up unlawful presence, and traveling during a pending adjustment case without advance permission can jeopardize the application. Get advice before any trip.

  • A Weak Affidavit of Support

    Income shortfalls, missing tax returns, or an unprepared joint sponsor can delay or sink a case, especially given the current focus on public charge.

Is a Family-Based Green Card a Good Fit?

Family-based green cards suit people who have a qualifying relative ready to sponsor them and stand behind that commitment financially. If you have a close relationship with a U.S. citizen or green card holder, this may be the right choice.
