How Long Does the U.S. Immigration Process Take?

How long the U.S. immigration process takes ranges from a few months to more than two decades, and the answer depends almost entirely on which category you qualify under and, for most family and employment categories, the country you were born in. A spouse of a U.S. citizen can often finish in roughly a year. A sibling of a U.S. citizen born in Mexico is currently looking at about 25 years before a visa number is even available. Naturalization after you already hold a green card runs about five to seven months. Everything else sits somewhere between those poles.

Family-Based Cases

Family immigration splits into two tracks with very different waits. Immediate relatives of U.S. citizens (spouses, unmarried children under 21, and parents of citizens who are at least 21) are exempt from annual visa caps.¹ With no quota, the only wait is paperwork. The median adjudication time for an immediate-relative Form I-130 is roughly 13 months as of early 2026.² After approval, adjustment of status or consular processing adds several months, and the median I-485 for family-based cases is about 5.5 months.

Everyone else falls into the preference categories, F1 through F4, which are capped every year.³ For these applicants, the petition approval is a small fraction of the total wait. The real wait is for your priority date to become current on the State Department’s Visa Bulletin. The June 2026 Visa Bulletin shows the current backlogs:⁴

F1, unmarried adult children of citizens: roughly 8 to 9 years for most countries, about 19 years for Mexico.
F2A, spouses and minor children of permanent residents: about 1 to 2 years for most countries.
F2B, unmarried adult children of permanent residents: roughly 8 to 9 years for most countries, over 17 years for Mexico.
F3, married children of citizens: about 14 years for most countries, 25 years for Mexico.
F4, siblings of citizens: about 17 years for most countries, roughly 19 years for India, and 25 years for Mexico.

These are the current backlogs as published, not worst-case projections. A sibling petition filed today from Mexico will not produce an available visa for roughly a quarter century.

Employment-Based Cases

Employment green cards have up to three phases, each with its own clock. Many EB-2 and EB-3 applicants start with a PERM labor certification, in which the employer must show no qualified U.S. worker is available.⁵ As of early 2026, the average analyst review runs about 503 calendar days, with audit-queue cases taking longer.⁶ That is roughly 17 months for the labor certification alone.

After PERM, the employer files Form I-140 to establish eligibility under one of the EB-1 through EB-5 categories.³ EB-1 applicants with extraordinary ability, outstanding professors and researchers, and multinational executives often skip PERM entirely. I-140 processing varies, and premium processing can compress it to 15 or 45 business days depending on classification.

The final step is Form I-485 to adjust status if you are in the United States, or consular processing abroad. The median I-485 for employment-based cases in FY 2026 is about 6.2 months.² But those medians only apply once your priority date is current. For applicants born in India, the EB-2 backlog stretches to September 2013 and the EB-3 backlog to December 2013, roughly a 12- to 13-year wait for a visa number.⁴ H-1B workers stuck in the backlog can extend beyond the six-year cap in one- or three-year increments if a PERM or I-140 was filed at the required point.⁷

K-1 Fiancé Visa

A U.S. citizen bringing a foreign fiancé files Form I-129F. Filing to visa issuance typically runs 8 to 11 months: roughly 7 to 8 months for USCIS adjudication, 4 to 6 weeks at the National Visa Center, and another 4 to 6 weeks to the embassy interview. After arrival, the couple has 90 days to marry, and the immigrant then files for adjustment of status. That adds roughly 5 to 6 more months based on current I-485 medians.²

Diversity Visa Lottery

The Diversity Visa program awards up to 55,000 green cards annually to nationals of countries with historically low U.S. immigration. Registration is short. For the DV-2026 cycle, it ran from October 2 to November 7, 2024. Selected applicants are notified the following spring and must complete their interview, obtain their visa, and enter the United States before the federal fiscal year ends on September 30, giving winners roughly 6 to 10 months from notification to entry. Any visa not issued by September 30 expires permanently.⁸

Asylum and Refugee Cases

Asylum and refugee processing follows its own tracks, and both tend to be slow. Affirmative asylum applicants, who apply proactively through USCIS, faced an average processing time of roughly 23 months in FY 2024. Defensive asylum cases go through immigration court and typically take longer because of court backlogs that have grown for over a decade. Refugee resettlement, which begins with a referral from the United Nations or a U.S. embassy overseas, has historically run 18 to 24 months from referral to arrival, though annual admissions ceilings and policy shifts move that number.

Naturalization

After holding a green card for the required period, five years in most cases or three years if married to a U.S. citizen, you can apply for citizenship on Form N-400.⁹ The national median processing time in 2026 runs about 5 to 7 months, though individual field offices are faster or slower. During that window, USCIS collects your fingerprints and runs FBI background checks, then interviews you and administers English and civics exams.¹⁰ Pass, and you are scheduled for an oath ceremony.

Why the Same Form Can Take Very Different Times

Several factors outside your control move a case from months to years.

Per-Country Caps

Federal law limits any single country’s nationals to 7 percent of the annual immigrant visa allocation.¹¹ India, China, Mexico, and the Philippines hit those caps every year, and the resulting backlogs stretch a decade or more. An EB-2 applicant born in Canada may have a current priority date while an identically qualified applicant born in India waits 13 years. The bottleneck is mathematical, not qualitative.

Office Workloads

USCIS operates multiple service centers and hundreds of field offices, and staffing and caseloads differ. The same form filed at one location can take months longer than at another. You can check location-specific timelines using the USCIS Case Processing Times tool by selecting your form type and the office handling your case.¹²

Requests for Evidence

If USCIS needs more documentation, it issues a Request for Evidence with a set deadline, typically 30 to 87 days. The officer’s review after your response adds further weeks or months. A Notice of Intent to Deny pauses everything while you rebut.

Security Checks

Every application triggers FBI fingerprint checks and name checks.¹⁰ Most clear quickly, but a name match against records in the FBI’s Universal Index can trigger extended review that takes months. Applicants from countries subject to heightened scrutiny may see additional delays with no published timeline. Security checks cannot be expedited.

Public Charge Review

USCIS evaluates whether an applicant is likely to become primarily dependent on government cash assistance under a “totality of the circumstances” standard, weighing employment, education, health, age, family size, and finances.¹³ A strong Affidavit of Support usually resolves the question, but a thin financial file can trigger RFEs that add months.

Interim Work and Travel Documents

An I-485 applicant can file Form I-765 for work authorization and Form I-131 for advance parole at the same time as the green card application. Current processing runs about 6 to 8.5 months for the work permit and about 16 to 19.5 months for advance parole. Leaving the country without advance parole while your I-485 is pending will usually cause USCIS to treat the application as abandoned. And effective October 30, 2025, USCIS ended the automatic extension of expiring work permits for most renewal applicants, so a slow renewal can now create an actual gap in work authorization.¹⁴

Ways to Shorten the Wait

Premium Processing

For certain employment-based petitions and applications, Form I-907 buys a guaranteed government response within a set timeframe. The 2026 fees range from $1,780 to $2,965 depending on the form and classification.¹⁵ The response windows are:¹⁶

15 business days for most Form I-129 and I-140 classifications.
30 business days for Form I-765 and certain I-539 change-of-status requests.
45 business days for I-140 multinational executive/manager and national interest waiver classifications.

If USCIS misses the deadline, it refunds the fee and continues prioritizing the case. A “response” can be an approval, denial, RFE, or notice of intent to deny. Premium processing is not available for family-based green cards, naturalization, or asylum.

Expedite Requests

For forms outside premium processing, you can submit a free expedite request through the USCIS contact center or your online account. USCIS considers expedites based on severe financial loss, urgent humanitarian situations, nonprofit interests, government interests including public safety or national security, and clear USCIS errors.¹⁷ Job loss alone generally will not qualify. You need documentation that the situation is genuinely urgent.

Federal Mandamus Lawsuits

When a case sits far beyond posted processing times with no explanation, a federal mandamus lawsuit can force USCIS to act. You must show the agency has a clear duty to adjudicate your case, that the duty runs to you, and that no other adequate remedy exists. Courts assess whether the delay is unreasonable under the Administrative Procedure Act. Filing typically requires an attorney and costs several thousand dollars, though the filing itself sometimes prompts a decision. This is a last resort after normal channels are exhausted, not a shortcut around them.
