How Long Does It Take to Immigrate to the US: Category and Backlogs

Immigrating to the United States takes anywhere from about one year to more than two decades, and the range is that wide for real reasons. How long it takes you to immigrate to the US depends almost entirely on three things: your relationship to a U.S. citizen or employer, your country of birth, and which visa category you fit into. Spouses, minor children, and parents of U.S. citizens move fastest, with a median processing time around 12.9 months for the initial petition alone.¹ Siblings of U.S. citizens born in high-demand countries can wait 20 years or longer before a visa number even becomes available. Paperwork speed is rarely the bottleneck. The bottleneck is whether Congress has allocated enough visa numbers for people in your category and from your country.

Why the Wait Depends on Category and Country

Federal law caps immigrant visas at roughly 675,000 a year: about 480,000 family-sponsored, 140,000 employment-based, and 55,000 through the diversity lottery.² When demand in a category exceeds supply, a queue forms. Each applicant gets a priority date based on when their petition was filed, and they wait until that date is called.

A separate rule makes the wait dramatically worse for people born in a handful of countries. No single country’s natives can receive more than 7% of the total family-sponsored and employment-based visas in any fiscal year.³ That cap treats a country of 1.4 billion the same as one of 5 million. The result is that applicants born in India, China, Mexico, and the Philippines face backlogs measured in years or decades, while someone in an identical category from a lower-demand country might have a visa available immediately.

The State Department publishes a Visa Bulletin each month showing which priority dates are currently being processed in each category.⁴ Comparing your priority date to the dates currently being called is the single most useful way to estimate your remaining wait.

Immediate Relatives of U.S. Citizens

Spouses, unmarried children under 21, and parents of U.S. citizens who are at least 21 are classified as immediate relatives. This group is exempt from the annual visa caps entirely.⁵ There is no line to wait in and no per-country limit. The only delay is government review time.

As of fiscal year 2026, the median processing time for an immediate-relative I-130 petition is about 12.9 months.¹ After approval, the applicant still completes either consular processing abroad or adjustment of status inside the U.S., which adds several months more. The realistic total from filing to green card runs roughly 12 to 24 months if nothing goes wrong.

Family Preference Categories

Everyone else sponsoring a family member falls into one of four preference categories, each with annual numerical limits.⁵ The further down the list, the longer the wait tends to be.

F1, unmarried adult children of U.S. citizens: several years to over a decade, depending on country of birth.
F2A, spouses and minor children of permanent residents: often the shortest family preference wait, sometimes under two years for most countries.
F2B, unmarried adult children of permanent residents: typically five to ten years.
F3, married adult children of U.S. citizens: a decade or more is common.
F4, siblings of adult U.S. citizens: the longest family-based wait. The June 2026 Visa Bulletin shows priority dates being processed from 2008 for most countries, 2001 for Mexico, and 2007 for the Philippines.⁶

To put those F4 numbers in perspective: if you’re a U.S. citizen filing a sibling petition today for someone born in Mexico, the current backlog implies a wait of roughly 25 years before a visa number becomes available. That figure isn’t hypothetical. It’s the gap between today and the priority dates being processed now.

Employment-Based Green Cards

Employment cases add layers that family cases don’t have, and each layer has its own clock. For most workers in the EB-2 and EB-3 categories, the process starts well before any immigration petition is filed.

PERM Labor Certification

Before an employer can sponsor most workers, the Department of Labor requires proof that no qualified U.S. worker is available. Defining the position, getting a prevailing wage determination, running a formal recruitment period, and then filing the PERM application itself all take time. The prevailing wage determination alone takes roughly six to eight months. As of early 2026, PERM applications that aren’t selected for audit are taking approximately 16 to 17 months. Audited cases run longer. Altogether, PERM can consume two years or more before the employer even files an I-140 with USCIS.

I-140 and the Visa Backlog

Once PERM is certified, the employer files Form I-140 to classify the worker under an employment-based preference category.⁷ USCIS reviews the worker’s education, experience, and skills against the job requirements.⁸

After I-140 approval, the worker enters the visa backlog queue, and this is where country of birth creates staggering gaps. The June 2026 Visa Bulletin shows EB-2 final action dates of September 2013 for India-born applicants, a backlog of roughly 13 years. China-born EB-2 applicants face about a five-year wait. Most other countries show current status, meaning no backlog at all.⁶

What the Total Looks Like

For a worker born in a country with no backlog, PERM plus I-140 plus final green card processing might take three to four years. For an Indian-born professional in EB-2, the realistic total from PERM filing to green card can exceed 15 years. That’s where most of the frustration in the employment-based system concentrates, and it’s why many skilled workers look at EB-1, which has shorter backlogs for extraordinary-ability applicants, or the EB-5 investor visa.

The Diversity Visa Lottery

The diversity visa program sets aside up to 55,000 green cards each year for randomly selected applicants from countries with historically low rates of immigration to the United States.⁵ Applicants from countries like India, China, Mexico, and the Philippines are typically ineligible because those countries already send large numbers of immigrants through other categories.

Registration opens each October for visas that will be available roughly two years later. Selected applicants complete consular processing and must receive their visa before the end of the fiscal year, because a diversity selection cannot be carried forward. From registration to green card, the whole process runs about 18 to 24 months for successful applicants. That makes it the fastest pathway for anyone who qualifies and gets selected. The catch is that millions enter and only about 55,000 are chosen.

Adjustment of Status vs. Consular Processing

Once a visa number is available and the petition is approved, applicants finish the process on one of two tracks. The choice affects both timing and what you can do while waiting.

Adjustment of Status

Applicants physically present in the United States file Form I-485 to become permanent residents without leaving the country.⁹ Biometrics come five to ten weeks after filing, and most applicants are then scheduled for an interview at a local USCIS field office. Employment-based I-485 cases currently take roughly 11 to 31 months from filing to decision, with wide variation by service center and case complexity. Pending I-485 applicants can apply for work authorization and travel documents in the meantime.

Consular Processing

Applicants living outside the United States go through the National Visa Center, which bridges USCIS approval and the final visa interview at a U.S. embassy or consulate. After the applicant pays fees and submits Form DS-260 with supporting civil documents, the NVC confirms the case is documentarily qualified and the file waits for an interview slot. Some embassies schedule interviews within weeks. Others have backlogs exceeding a year. After a successful interview, the applicant receives a visa stamp and completes admission at a U.S. port of entry.

What Can Stretch or Shorten the Timeline

Two things reliably slow cases down. The first is a Request for Evidence. If a USCIS officer finds the file incomplete, the case pauses while the applicant responds; most petition types get 84 days to reply, and Form I-539 applicants get 30.¹⁰ Deadlines are firm. An RFE can easily add three to four months. The second is background and security checks. USCIS and the FBI run fingerprints and name checks in parallel with case review, and if something triggers additional screening, months of delay can pass with no clear timeline.

Every applicant also needs an immigration medical exam. Adjustment applicants visit a USCIS-designated civil surgeon who completes Form I-693.¹¹ Consular applicants see a panel physician approved by the embassy. The exam itself is usually one appointment, but gathering vaccination records and lab results can stretch it to several weeks. Booking too early is also a risk, because results have a limited validity window.

On the acceleration side, some employment petitions qualify for premium processing. For an I-140, the fee is $2,965 as of March 2026, and USCIS guarantees action in 15 business days for most classifications or 45 business days for multinational executive/manager cases and EB-2 National Interest Waivers.¹² Premium processing speeds up only the petition review. It does nothing about the visa backlog. An Indian-born professional whose I-140 is approved in 15 days still faces a decade-plus wait for a visa number.

Applicants who don’t qualify for premium processing can request expedited handling based on severe financial loss, humanitarian emergencies, or a clear USCIS error.¹³ These are granted at USCIS’s discretion and require strong evidence. Simply wanting work authorization sooner is not enough.

When a Child Might Age Out

Long backlogs create a specific danger for families: a child included on a parent’s petition can turn 21 and lose eligibility as a derivative beneficiary. The Child Status Protection Act provides partial relief by adjusting how a child’s age is calculated.¹⁴ Take the child’s age on the date a visa becomes available and subtract the number of days the petition was pending. If the resulting CSPA age is under 21 and the child remains unmarried, the child still qualifies. In heavily backlogged categories, though, children can age out even after the subtraction, which is why families in that position often plan filings with a lawyer early.

After the Green Card: The Citizenship Clock

For many people, receiving a green card starts a new timeline rather than ending one. Most permanent residents become eligible to apply for naturalization after five continuous years of permanent residence.¹⁵ Permanent residents married to U.S. citizens can apply after three years, provided they’ve been living in marital union with their citizen spouse during that time. Naturalization itself adds several more months for the N-400, biometrics, English and civics interview, and oath ceremony. Someone who entered as an immediate relative spouse and later naturalized typically spends about five to six years total from initial petition to U.S. citizenship. Someone who waited a decade in a family preference or employment backlog before getting a green card should add five more years on top of that wait.
