How long does it take to become a U.S. citizen? Timelines & Step-by-Step Guide

Becoming a U.S. citizen can take several years for many foreign nationals. How you qualify for citizenship has a huge impact on when you can file, and your location may affect how long USCIS takes to process your case.

The typical U.S. citizenship timeline in 2026

Many people obtain U.S. citizenship by first becoming permanent residents. The time it takes to get a Green Card varies significantly — and for some, it may take several decades to even qualify for one.

Once a foreign national obtains permanent residency, they must wait several years before they can file for citizenship. Below is a table outlining the wait times permanent residents must complete before applying for citizenship:

Once you are able to file Form N-400, you’ll need to wait for USCIS to process your case. As of January 2026, it takes the federal agency 6.5 to 12 months to complete 80% of petitions. Depending on which field office reviews your application, you may experience shorter or longer wait times. 

Several factors affect how long it takes someone to become a U.S. citizen. These include:

• Whether you qualify for a shorter wait time
• Whether your designated USCIS service center experiences staff shortages
• Whether your case requires additional review from an immigration officer

For most people, the total time it takes to become an American citizen depends on when and how they get a Green Card. Given that there are many pathways to permanent residence, consider working with an immigration lawyer. They can offer you long-term strategies for obtaining citizenship, regardless of your current immigration status.

What actually determines how long it takes to become a U.S. citizen

Below are some factors that may impact the time it takes for you to become a U.S. citizen:

• Immigration pathway: Your current status may require you to wait or seek another status before you can file for citizenship. 
• Where your case gets processed: Some adjudicating offices take longer to get to your petition.
• Strength of case: Incomplete N-400 or N-600 petitions are more likely to receive RFEs or denial notices.

While you can’t control many of these factors, you have the ability to create a strong petition and remain proactive in case USCIS communicates with you. You should:

• Make sure you correctly fill out all forms and petitions
• Submit strong, sufficient evidence
• File on time, and respond in a timely manner to USCIS notices
• Attend your biometrics and interview appointment
• Prepare for the citizenship test and interview

U.S. citizenship eligibility timelines by category

Below are the three main categories that qualify people for U.S. citizenship. Depending on how you’re applying for naturalization, the amount of time you need to wait before filing will differ considerably.

Green Card holders

Permanent residents can request citizenship five years after the “Resident Since” date outlined in their Green Card. However, USCIS does allow people to submit an N-400 petition up to 90 days early.

Marriage to a U.S. citizen

Immigrants who obtained permanent residence through marriage can become U.S. citizens after three years. They can also benefit from USCIS’ early filing rule, which allows them to send Form N-400 up to 90 days before their three-year permanent residency anniversary date. 

While those who file for U.S. citizenship through marriage don’t wait as long as other Green Card holders, they do have to meet additional requirements. Immigrant spouses must:

• Live together with their partner prior to obtaining permanent residency
• Have proof that they cohabitated for three years since, and
• Continue to remain together during the naturalization process.

Due to this rule, most Green Card holders who become divorced or widowed are unable to file within three years. However, they may be able to request citizenship five years after their permanent residency anniversary date.

Military service

Green Card holders who serve in the military are able to request citizenship after a year of honorable service. But those who served during a designated period of wartime may be able to apply sooner. These conflicts are: :

• World War I, from April 6, 1917 to November 11, 1918
• World War II, from September 1, 1939 to December 31, 1946
• The Korean War, from June 25, 1950 to July 1, 1955
• The Vietnam War, from February 28, 1961 to October 15, 1978
• The Persian Gulf Conflict, from August 2, 1990 to April 11, 1991
• The War on Terrorism, from September 11, 2001 onwards

If you have served or are currently serving during a period of conflict, you are able to submit an N-400 petition. However, you’ll need a certificate of honorable discharge or a completed Form N-426 if you’re still in active duty.

The naturalization process timeline after you’re eligible

Below are the steps in the naturalization process, as well as how long they take.

Filing Form N-400

As of January 2026, it takes over half a year to a year for USCIS to process most N-400 petitions. To see an estimate of how long your designated service center takes to process your application, check out USCIS’s Processing Times tool. 

During this stage, USCIS will check that you’ve filled out Form N-400 correctly and verify that you qualify for naturalization. 

Biometrics appointment

Sometime after you’ve filed Form N-400, you may receive a request to attend a biometrics appointment from USCIS. During this step, you’ll go to your designated Application Support Center (ASC) and submit fingerprints, photographs, and your digital signature.

USCIS does not provide a timeline on when they send out biometrics appointment requests. However, Manifest immigration attorney Ana Gabriela Urizar says most people receive notices a few weeks after initial filing.

“Most people hear back from USCIS within a month or two, but you may or may not receive a notice before or after then,” Urizar says. “Your designated field office will have a big impact on when you get scheduled for biometrics, and how busy reviewing officers are.”

Naturalization interview and tests

After your biometrics appointment, USCIS will schedule you for a citizenship test. This is often one of the last and most important steps in the naturalization process. USCIS doesn’t explicitly say when appointments are made after filing. However, Urizar says people should expect to get scheduled several months after filing N-400. 

During your appointment, an immigration officer will interview you to verify or follow up on information you submitted in your initial application. They will also ask you a series of questions that cover U.S. history and government. 

Oath ceremony

After you complete and pass the naturalization assessment, USCIS will schedule you for an Oath of Allegiance ceremony. If possible, you may take the Oath on the same day as your citizenship test. Otherwise, Urizar says most people wait a few weeks before they get an appointment notice from USCIS. It is important to note that you are not officially a US citizen until after you complete the Oath of Allegiance ceremony. 

Common reasons U.S. citizenship applications take longer than expected

U.S. citizenship applications can often take longer when:

• Forms are not properly filed: Missing evidence, incorrect fees, or incomplete answers can cause processing delays, requests for evidence, or even denial notices. 
• Backlogs affect your respective field office: Processing times vary by location, especially when there are staffing shortages or high case volumes.
• You reschedule appointments with USCIS: Depending on the availability at your local office, you may have to wait several weeks if you need to skip your initial biometrics or interview appointment. 
• Continuous presence requirement not met: This could happen if you traveled a lot recently.

Can you speed up the U.S. citizenship timeline?

You can’t speed up how long it takes for you to qualify to become a U.S. citizen. Unlike many other immigrant petitions, USCIS does not allow people to request premium processing for Form N-400. To become a U.S. citizen, you’ll need to get permanent residence and:

• Either wait up to five years before filing,
• Get married to a U.S. citizen or Green Card holder, or
• Serve honorably in the U.S. military.

Most people can’t control when they can file for U.S. citizenship, but they can save a lot of time by remaining proactive in their case. Filing early and working in advance to strengthen your N-400 petition can make a huge difference in mitigating unfavorable notices or requests for evidence, which can significantly delay how long USCIS takes to make a decision.

Consulting with an immigration attorney makes a big difference here. With their expertise in immigration law, they can offer you tailored advice on how to:

• Best prepare documents  
• Anticipate parts of your application that might raise flags to a USCIS officer
• Prepare for the citizenship test and interview

Remember: Becoming a U.S. citizen is an investment in your future. Prior to filing, consider working with a lawyer who best understands the nuances of your case. Informed, strategic filing can help you avoid delays and unfavorable decisions.
