What family-based immigration means
Family-based immigration is a set of U.S. immigration pathways that let certain foreign citizens become permanent residents (get a “green card”) because they have a qualifying family relationship with a U.S. citizen or a lawful permanent resident (green card holder).
In the United States, family-based immigrant visas fall into two big groups. The first group is Immediate Relative visas (close family of U.S. citizens), which are not limited by an annual numerical cap. The second group is Family Preference visas (certain more distant relatives of U.S. citizens and certain relatives of lawful permanent residents), which are limited each fiscal year.
This system is built around one straightforward idea: the government gives special weight to keeping close families together, while also using category rules and annual limits to manage demand when more people apply than the law allows in a given year.
Quick category finder
Match the family relationship with the sponsor’s status to identify the likely family-based immigration category.
| Relationship / Family Member | Sponsor: U.S. Citizen | Sponsor: Green Card Holder |
|---|---|---|
| Spouse | IR1 / CR1 Immediate Relative Uncapped |
F2A Family Preference Capped |
| Child (unmarried, under 21) | IR2 / CR2 Immediate Relative Uncapped |
F2A Family Preference Capped |
| Son or daughter (unmarried, 21+) | F1 Family Preference Capped |
F2B Family Preference Capped |
| Son or daughter (married) | F3 Family Preference Capped |
Not eligible |
| Parent | IR5 Immediate Relative Uncapped; sponsor must be 21+ |
Not eligible |
| Brother or sister | F4 Family Preference Capped; sponsor must be 21+ |
Not eligible |
Notes your readers will appreciate
“Child” is a legal term in U.S. immigration. In general, it means an unmarried person under 21. Some relationships (like stepchildren) also have special rule details.
Immediate Relative cases do not automatically “include” children as add-ons. For example, the State Department explains that a child does not receive derivative status on an Immediate Relative petition, which is why children typically need their own petitions in those situations.
By contrast, in preference categories, U.S. law can allow a principal applicant’s spouse and children to receive the same status and place in line when they are accompanying or following to join.
What the category labels mean
Immediate Relative vs Family Preference
The easiest way to understand the labels is to connect them to annual limits.
Immediate Relative (IR/CR codes) generally refers to close family of U.S. citizens (such as spouse, minor child, parent). These visas are not numerically limited each fiscal year, which is why people in these categories often do not wait on a quota “line” in the same way preference categories do.
Family Preference (F codes) covers specific relatives in categories such as F1, F2A, F2B, F3, and F4. These categories are numerically limited, and the government uses priority dates to manage the line.
Priority dates and the Visa Bulletin
When a category is numerically limited, approval of a petition is not always the same as having a visa immediately available. The State Department explains that even if a petition is approved, a person may not get an immigrant visa number right away because U.S. law limits visas by category and also limits visas by country in certain ways.
That is why the State Department publishes the monthly Visa Bulletin. It shows “Final Action Dates” (when visas can be issued) and “Dates for Filing” (when applicants may start submitting documents, depending on the process and agency instructions).
For context, the State Department’s April 2026 Visa Bulletin states that the fiscal year 2026 limit for family-sponsored preference immigrants is 226,000, and it describes the 7% per-country limit for preference immigrants (shown as 25,620 for FY 2026).
The same bulletin lists “oversubscribed” chargeability areas where demand is high, including China (mainland-born chargeability area), India, Mexico, and the Philippines.
Step-by-step roadmap
This section is designed to read like a flowchart. It focuses on the most common family-based cases and names the agencies involved.
The agencies you will keep seeing
- U.S. Citizenship and Immigration Services: decides immigrant petitions (like Form I‑130) and handles many green card applications from inside the U.S.
- U.S. Department of State: runs immigrant visa processing abroad through embassies/consulates and publishes the Visa Bulletin.
- National Visa Center: handles “pre-processing” for many immigrant visa cases after petition approval, including creating the case and guiding document submission before an interview can be scheduled.
- Department of Homeland Security: the larger department that includes USCIS and the border agency that decides admission at entry.
- U.S. Customs and Border Protection: at the port of entry, CBP has authority to admit or refuse entry even if a person has a visa, and it admits people as lawful permanent residents when appropriate.
Flowchart overview
Start → identify your category → file a petition → wait for approval + (if needed) a visa number → complete the visa or green card application steps → interview/screening → become a permanent resident
The exact steps depend on whether the beneficiary is outside the U.S. (consular processing) or inside the U.S. (adjustment of status).
Step-by-step
Step one
Confirm the sponsor can file for this relationship. The State Department summarizes who can petition: U.S. citizens can petition for spouse, son/daughter, parent, and brother/sister; lawful permanent residents can petition for spouse and unmarried son/daughter.
Step two
File the family petition (usually Form I‑130). The State Department’s immigrant visa process explains that U.S. citizens and lawful permanent residents residing in the U.S. must file Form I‑130 with USCIS, and the petition must be approved before the case can proceed to NVC.
Step three
Wait for approval, and—if you are in a capped category—wait for your priority date to be current. The State Department explains that some categories are limited each year and by country, so even after approval you may not get a visa number immediately.
Step four
Choose your track: outside the U.S. vs inside the U.S.
- If the beneficiary is outside the U.S., the case usually moves into consular processing through the State Department system.
- If the beneficiary is inside the U.S., the process may be adjustment of status, which is handled through USCIS using Form I‑485 (eligibility depends on category and the person’s status).
Step five
Consular processing path begins: NVC creates the case and sends instructions. After USCIS approves the petition, the State Department explains that it transfers the case to NVC for pre-processing, and NVC sends a “Welcome Letter” so applicants can log in and manage the case online.
Consular processing uses the State Department’s Consular Electronic Application Center to manage fees, forms, messages, and document submission.
Step six
Submit the financial sponsorship form (I‑864) and required documents. In many family cases, the sponsor signs an Affidavit of Support (Form I‑864). The State Department explains that it is legally enforceable, typically lasts until the immigrant becomes a U.S. citizen or earns 40 qualifying quarters of work, and may require reimbursement if certain means-tested public benefits are received.
If the sponsor’s income is not enough, the State Department also explains that a joint sponsor may submit an I‑864.
Step seven
Complete the online immigrant visa application (DS‑260). The State Department states that after fees show as paid in CEAC, the applicant and each qualified family member immigrating with the applicant must complete Form DS‑260, and the DS‑260 confirmation page must be printed for the interview.
Step eight
Prepare for the interview: medical exam + documents. The State Department requires immigrant visa applicants to complete a medical examination with an embassy-approved panel physician before the interview; exams by other doctors are not accepted.
U.S. immigration law also requires certain vaccinations before an immigrant visa can be issued, and panel physicians must verify vaccination compliance (or that a vaccine is medically inappropriate).
Step nine
Attend the visa interview at a U.S. embassy or consulate. The State Department instructs applicants to attend on the scheduled date and bring the printed DS‑260 confirmation page; a consular officer interviews the applicant and takes digital fingerprints as part of the process.
The State Department also warns applicants not to make irreversible financial plans until they actually have the visa.
Step ten
After approval: pay the immigrant fee, travel, and enter the U.S. as a permanent resident. The State Department instructs approved applicants to pay the USCIS Immigrant Fee after receiving the immigrant visa and before traveling, and it states USCIS will not issue the physical green card until the fee is paid.
The State Department notes that an immigrant visa is usually valid for up to six months, but it can be valid for less time if the medical exam expires sooner.
At entry, the State Department explains that a visa does not guarantee admission and that CBP has authority to grant or deny admission; when admitted, the person enters as a lawful permanent resident.
Adjustment of status in one quick flow
If the beneficiary is already in the U.S., USA.gov points people to adjustment of status, and USCIS uses Form I‑485 for people in the U.S. applying to register permanent residence or adjust status.
In practice, USCIS may require biometrics (fingerprints/photo/signature) and may require an interview unless it is waived, as described in USCIS guidance materials.
For preference categories, that “visa number availability” concept still applies inside the U.S. The Visa Bulletin explains the basic priority-date order rules, and USCIS and consular officers use the Visa Bulletin charts as part of allocation and filing decisions.
Numbers, wait times, and how the system got here
What the numbers look like today
Family-based pathways remain one of the largest channels into permanent residence.
In FY 2024, the Migration Policy Institute reports that close to 1.4 million people became lawful permanent residents, and it estimates that 49% were immediate relatives of U.S. citizens (uncapped) while 14% were in family-sponsored preference categories (capped by visa and country limits).
Looking specifically at family preference categories (the capped side), the State Department’s FY 2024 annual tables show 215,959 “Family Preferences” in total, with a large share in second preference (F2) and a sizeable total for F4 (siblings of U.S. citizens).
For immediate relatives processed as immigrant visas abroad, the State Department’s FY 2024 annual report shows 265,467 immediate relative immigrant visas issued by consular posts worldwide (grand total).
One reason different sources show different totals is that “visas issued abroad” and “new lawful permanent residents” are not identical measures. The State Department explains that its annual Report of the Visa Office provides consular visa issuance statistics and does not include certain categories of people adjusting status inside the U.S. through USCIS, especially non-numerically controlled adjustment categories.
Why some families wait longer than others
Wait time is mostly driven by whether the relationship falls into an uncapped Immediate Relative group or a capped Family Preference group.
In FY 2026 (as stated in the April 2026 Visa Bulletin), the worldwide limit for family-sponsored preference immigrants is set at 226,000, with per-country limits applying through the preference system.
The Visa Bulletin also explains what “oversubscribed” means: when the government cannot satisfy all reported demand within numerical limits, it sets a cutoff date based on priority dates.
A short history in plain language
Modern family-based immigration traces heavily to major reforms in 1965. The U.S. House of Representatives history office notes that the 1965 immigration law created new opportunities for immigrants—particularly from Asia—to join relatives in America, and that immigration patterns shifted significantly after the reform.
The National Archives describes the 1965 law as emphasizing family reunification (and, to a lesser extent, occupational skills and refugee status) in the context of broader civil-rights-era changes.
President Lyndon B. Johnson signed the 1965 law, which became a turning point in how the U.S. structured legal immigration priorities, including the role of family ties.
