Family-Based Green Cards: A Plain-Language Guide

Family-based immigration is the single largest source of green cards in the US system. More than two-thirds of all permanent residence grants each year come through family relationships — spouses, children, parents, and siblings of US citizens and lawful permanent residents (LPRs).

The system is organized into two main tracks: Immediate Relatives (IRs) of US citizens, who have no annual cap and move through the process relatively quickly, and Family Preference categories (F1, F2A, F2B, F3, F4), who face annual numerical caps and often significant waits based on country of origin and preference category. Understanding which category a particular relationship falls into determines everything about the timeline.

A note: If you’re worried about encountering US Immigration and Customs Enforcement (ICE) at any point in this process, our Know Your Rights guide covers what to do.

This page covers the two tracks and all the categories within them, who qualifies, how priority dates and the Visa Bulletin work, adjustment of status vs consular processing, what it costs, how long each category takes, and what quietly kills family-based petitions.

The two tracks

Immediate Relatives (no annual cap)

Immediate Relatives of US citizens are not subject to numerical limits — they get a green card as soon as the petition is approved and the applicant completes the visa process. The three Immediate Relative categories:

IR-1 / CR-1 — Spouse of US citizen. CR-1 (Conditional Resident) if the marriage is less than 2 years old at green card issuance; IR-1 if the marriage is 2+ years old.
IR-2 — Unmarried child under 21 of US citizen.
IR-5 — Parent of US citizen (the US citizen petitioner must be 21 or older).

Also treated similarly, with separate category codes:

IR-3 / IR-4 — Children adopted abroad by US citizens (specific adoption pathways).
IW — Widow or widower of US citizen (if the marriage lasted at least two years and the petition is filed within two years of the citizen’s death — technically a self-petition, not through the citizen directly).

Family Preference (annual caps, priority date waits)

Family Preference categories are capped at a total of approximately 226,000 visas per year, distributed across four preferences:

F1 — Unmarried adult (21+) children of US citizens. ~23,400 visas per year.
F2A — Spouses and unmarried minor children of LPRs. ~87,900 visas per year (plus unused F1 visas spilling over).
F2B — Unmarried adult (21+) children of LPRs. ~26,300 visas per year.
F3 — Married children of US citizens (any age). ~23,400 visas per year.
F4 — Siblings of US citizens (US citizen petitioner must be 21 or older). ~65,000 visas per year.

Each category has waiting lists that vary by country of birth. India, Mexico, the Philippines, and (sometimes) China have significant backlogs in multiple categories. “All other countries” generally moves faster.

Siblings of LPRs are not eligible for any family-based petition. The LPR must naturalize to US citizenship before petitioning for a sibling.

Parents of LPRs are not eligible for any family-based petition. The LPR must naturalize before petitioning for a parent.

Married children of LPRs are not eligible. The LPR must naturalize, after which the children become F3 eligible.

Who qualifies as the petitioner

A US citizen or lawful permanent resident files Form I-130 (Petition for Alien Relative) on behalf of a qualifying family member.

US citizens can petition for:

Spouse (IR-1/CR-1)
Unmarried children under 21 (IR-2)
Unmarried adult children 21+ (F1)
Married children of any age (F3)
Parents, if petitioner is 21 or older (IR-5)
Siblings, if petitioner is 21 or older (F4)

Lawful permanent residents can petition for:

Spouse (F2A)
Unmarried children under 21 (F2A)
Unmarried adult children 21+ (F2B)

LPRs cannot petition for married children, parents, or siblings. Those petitions require US citizenship.

Who qualifies as the beneficiary

The beneficiary must have the qualifying family relationship with the petitioner. Documentation of the relationship is central to every family-based petition.

Spouse

Legal marriage, recognized in the place where celebrated
Marriage must still exist at the time of petition filing and green card issuance
Marriage entered in good faith (not solely for immigration purposes)
Same-sex marriages are recognized the same as opposite-sex marriages
Marriages while in removal proceedings face heightened scrutiny
Prior marriages must be legally terminated with evidence

Child

Biological child, adopted child, or stepchild
For stepchildren, the marriage creating the step-relationship must have occurred before the child turned 18
For adopted children, specific requirements apply depending on the type of adoption (immediate relative adoption, Hague Convention adoption, or orphan adoption)
“Child” under immigration law includes stepchildren, legitimated children, adopted children (with specific requirements), and children born out of wedlock

Parent

Biological parent, adoptive parent, or stepparent
For stepparents, the marriage creating the step-relationship must have occurred before the child turned 18
Petitioning US citizen must be 21 or older
Documentation of the parent-child relationship (birth certificate naming the parent) is critical

Sibling

Shared at least one biological or adoptive parent with the petitioner
Half-siblings, step-siblings (with qualifying step-relationship), and adopted siblings all qualify
Petitioning US citizen must be 21 or older

How priority dates and the Visa Bulletin work

For Immediate Relative petitions, there’s no priority date wait — the process moves forward as soon as the I-130 is approved.

For Family Preference petitions, the “priority date” is the date USCIS received the I-130. This date determines the beneficiary’s place in line.

Each month, the US Department of State publishes the Visa Bulletin. This document shows:

The Final Action Dates — the priority date that must be current for a visa to actually be issued.
The Dates for Filing — the priority date that must be current for the beneficiary to begin preparing the I-485 (adjustment of status) or final consular processing documents.

Each category and country combination has its own cutoff dates. If your priority date is before the cutoff date for your category and country, you can proceed. If it’s after, you wait.

Visa Bulletin example (illustrative only)

A hypothetical Visa Bulletin might show:

Category	All Other Countries	China	India	Mexico	Philippines
F1	2016 priority date	2016	2015	2004	2012
F2A	Current	Current	Current	Current	Current
F2B	2017	2017	2016	2005	2013
F3	2010	2010	2010	2001	2003
F4	2008	2008	2006	2001	2004

For the current actual Visa Bulletin, check travel.state.gov/content/travel/en/legal/visa-law0/visa-bulletin.html.

What this means in practice

F2A often has no wait or a very short one. This is the fastest family preference category.
F4 siblings have the longest waits — 15+ years is normal for “all other countries,” 20+ years for the Philippines and Mexico.
F3 and F4 for Mexico and the Philippines can wait 20+ years. In some cases, the US citizen petitioner may not live long enough to see the sibling or married child’s priority date become current.
Priority dates can retrogress. The Visa Bulletin dates can move backward if a category becomes oversubscribed, which can push back cases that seemed close to processing.

The two paths to a green card

Adjustment of status (if the beneficiary is in the US)

If the beneficiary is physically in the US in a lawful status (or qualifies under certain exceptions, such as INA §245(i) grandfathering), they can file Form I-485 (Application to Register Permanent Residence or Adjust Status) with USCIS.

Who can adjust in the US:

Immediate Relatives (IR-1, IR-2, IR-5, etc.) who entered lawfully — even if they later fell out of status, in most cases
Family Preference beneficiaries whose priority date is current, AND who maintained lawful status (or qualify for an exception)
Beneficiaries grandfathered under old §245(i) provisions (petitions filed on or before April 30, 2001, with specific requirements)

Advantages of adjustment of status:

Beneficiary can remain in the US during processing
Work authorization (EAD) and advance parole become available while the I-485 is pending
No interview at a US consulate abroad required (though USCIS interview in the US is required)
Family members can adjust together in parallel

Consular processing (if the beneficiary is abroad)

If the beneficiary is outside the US — or inside the US but ineligible to adjust — the case goes through the National Visa Center (NVC) and then to a US consulate abroad.

Steps:

I-130 approved by USCIS
Case transferred to National Visa Center
NVC collects fees, civil documents, and the DS-260 immigrant visa application
NVC schedules consular interview
Beneficiary attends interview at US consulate
If approved, receives immigrant visa and travels to US to activate green card

Timing considerations for consular processing:

Beneficiary cannot work in the US while abroad (obvious, but important)
Beneficiary cannot visit the US on a non-immigrant visa while the immigrant visa is pending (presumption of immigrant intent)
NVC and consular processing can add 6-18+ months to the timeline

How to apply

Step by step (typical family-based process):

Petitioner files Form I-130 (Petition for Alien Relative) with USCIS, with evidence of the qualifying relationship. Filing fee is $675.
USCIS adjudicates the I-130. Processing time varies dramatically by category — Immediate Relative spouse petitions filed by US citizens often process in 12-18 months. F-category petitions can take similar or longer.
For Immediate Relatives: Case proceeds immediately to adjustment of status (if beneficiary in US) or NVC/consular processing (if abroad).
For Family Preference: Case waits in the queue for the priority date to become current.
When priority date is current (or immediately for IR): File Form I-485 (if adjusting) or complete consular processing (if abroad).
USCIS interview (for I-485) or consular interview (for consular processing).
Green card issued.

For spouses of US citizens: a note on concurrent filing

Spouses of US citizens who are physically in the US and eligible to adjust status can file I-130 and I-485 concurrently (at the same time). This streamlines the process significantly compared to sequential filing.

See the Marriage Green Card guide for full detail on the spouse-of-citizen path.

What it costs

Government fees:

Form I-130: $675
Form I-485 (adjustment of status, if adjusting in US): $1,440 per family member (includes biometrics and EAD/AP for applicants under 14)
Immigrant visa fees (if consular processing): $345 application fee plus $120 affidavit of support fee
USCIS Immigrant Fee (after visa issuance, before entering US or shortly after): $235 per person
Medical examination: $200-500 (varies by provider)

Attorney fees: Vary dramatically by complexity. Simple spouse-of-citizen petitions can run $2,000-5,000. Complex cases (prior immigration violations, criminal history, documentation challenges) can run $5,000-15,000+.

Total government fees for a typical case: $1,500-3,500 per family member, depending on path and age.

How long it takes

Immediate Relatives (no priority date wait):

Spouses of US citizens (CR-1/IR-1):

Concurrent filing + adjustment of status: typically 12-24 months
Consular processing: typically 12-30 months

Children of US citizens (IR-2):

Similar to spouses, 12-30 months depending on path

Parents of US citizens (IR-5):

Similar, 12-30 months

Family Preference:

Processing time has two parts: I-130 adjudication, and priority date wait.

I-130 adjudication: Typically 1-3 years, variable.

Priority date wait after I-130 approval: The main variable. Representative waits (not current — check Visa Bulletin):

F2A spouses/children of LPRs: Usually current or short wait
F2B adult children of LPRs: 5-10+ years, longer for Mexico and Philippines
F1 adult children of US citizens: 7-10+ years, 20+ for Mexico and Philippines
F3 married children of US citizens: 12-15+ years, 20+ for Mexico and Philippines
F4 siblings of US citizens: 15+ years all countries, 20+ for Mexico and Philippines

For adopted children, abandoned children, and complex family situations

Timing varies significantly based on the specific adoption type (immediate relative, Hague, orphan), country-specific adoption requirements, and documentation challenges. These cases often require specialized attorney involvement.

The affidavit of support

Every family-based immigrant visa requires an Affidavit of Support (Form I-864) from the petitioner, demonstrating that the petitioner can financially support the beneficiary at 125% of the federal poverty guidelines.

What the affidavit does:

Legally binds the petitioner to support the beneficiary financially
Can be enforced by the beneficiary against the petitioner if the beneficiary needs public assistance
Lasts until the beneficiary naturalizes, has worked 40 qualifying quarters (10 years), dies, or permanently leaves the US

If the petitioner can’t meet the income requirement, joint sponsors can supplement the primary sponsor. Joint sponsors face the same long-term financial obligation.

This is one of the more consequential documents in family-based immigration. Many petitioners don’t fully understand the long-term financial commitment they’re making.

What kills family-based petitions

In rough order of frequency:

1. Documentation of relationship problems. Missing or defective birth certificates, marriage certificates, divorce decrees, or adoption papers. For foreign documents, lack of proper authentication (apostille or consular authentication) and English translation.

2. Marriage fraud concerns (spouse cases). The Stokes interview, where USCIS officers separately interview spouses to detect inconsistencies, catches many problematic cases.

3. Prior immigration violations. Overstays, prior removal orders, unauthorized work, prior fraud. Many are waivable, but add complexity.

4. Criminal history. Certain crimes create inadmissibility grounds, some waivable, some not.

5. Priority date retrogression. Not technically a “killer” but can push cases back years when category/country combinations become more oversubscribed.

6. Petitioner changes. Death of the petitioner (there are provisions for survival of some petitions), loss of status, or changes in family relationship (divorce, marriage of beneficiary) can affect the petition.

7. Children aging out. Child beneficiaries who turn 21 during the process can lose eligibility, though CSPA (Child Status Protection Act) provides some protection.

8. Public charge concerns. Though less of an issue than it was in 2019-2020, insufficient I-864 financial support or evidence of likelihood to need public benefits can affect cases.

Children aging out: CSPA

The Child Status Protection Act (CSPA) provides age-protection for certain beneficiaries who are under 21 at the time of petition filing but turn 21 before their case is approved.

How it works (simplified):

For Immediate Relative child petitions, the child’s age “freezes” when the I-130 is filed, if filed before the child turned 21.
For Family Preference petitions, the CSPA age is calculated as: child’s actual age at visa availability − time the I-130 was pending.
If the CSPA age is under 21 and the beneficiary “sought to acquire” permanent residence within one year of visa availability, they remain eligible.

CSPA is complicated. Children close to 21 in family-based cases often need specific CSPA analysis to determine eligibility.

Where to go from here

If this is your first time looking at family-based immigration:

Identify your category. The relationship between petitioner and beneficiary determines the category, which determines the timeline. Immediate Relatives of US citizens have no priority date wait; Family Preference categories do.
Check the current Visa Bulletin. For Family Preference cases, the current Visa Bulletin cutoff dates tell you how far from “current” your priority date is.
Determine the right path. Adjustment of status (in the US) vs consular processing (abroad) have different requirements, timelines, and advantages.
Prepare financial documentation. The Affidavit of Support is a significant long-term obligation. Petitioners should understand it before filing.
For complex cases, consult an attorney. Prior immigration violations, criminal history, questions about relationship documentation, or categories involving adopted children benefit from legal review.

Family-based immigration is the backbone of US permanent residence pathways. For Immediate Relatives of US citizens, it is often the fastest and most direct path. For Family Preference beneficiaries from backlogged countries, patience is a central part of the strategy — but the ultimate destination is the same.
