Fastest Way to Get U.S. Citizenship in 2026

The fastest way to get U.S. citizenship is through parents, followed by military service (can be eligible in less than 1 year), or marriage to a U.S. citizen (can be eligible in 3 years).  

While some pathways, such as citizenship through parents or military service, are faster, many foreign nationals, particularly investors and skilled professionals, obtain U.S. citizenship through naturalization. This comes after securing permanent residency through investment or employment-based visa programs such as the EB-5, EB-2 NIW, EB-1, etc. 

There is no way to obtain U.S. citizenship instantly. Most pathways require you to meet the eligibility requirements and complete a legal process that usually starts with obtaining permanent residency (Green Card).  

This post will serve as a guide to the fastest ways to obtain U.S. citizenship, while highlighting all the available pathways.  

Key Takeaways – Fastest Way to Get U.S. Citizenship

The fastest way to get U.S. citizenship is through having citizen parents if you’re under 18 years, military service, or marriage to a U.S. citizen. 

The most common way for foreigners to obtain U.S. citizenship is through naturalization after 5 years of permanent residency via immigrant visas such as the EB5 and EB2 Visas, etc.  

Military service can allow eligible individuals to apply for expedited naturalization, sometimes in less than one year. 

Marriage to a U.S. citizen allows individuals to apply for naturalization after three years as a permanent resident. 

The table below compares the fastest legal pathways to becoming a United States citizen based on eligibility, timelines, and requirements.  

There are four main ways to obtain U.S. citizenship: 

1. Naturalization 
2. Through your parents 
3. Military service 
4. Marriage 

Many immigrants begin their citizenship journey in the United States by obtaining a Green Card and becoming permanent residents first.   

Naturalization is one of the most common ways for foreign nationals to become U.S. citizens. The main requirement to qualify for naturalization is to have been a permanent resident (Green Card holder) for 5 years. Apart from marriage and military service, there are several immigrant visa pathways for foreign nationals to obtain a Green Card, such as:  

• EB-5 Visa: Obtain permanent residence through job creation and capital investment in the United States. 
• EB-1 Visa: Permanent residency granted to foreign nationals with extraordinary ability, outstanding academics, or multinational executives at the top of their fields. 
• EB-2 NIW: Permanent residency granted to foreign individuals with advanced degrees or exceptional ability.  
• Gold Card: Green Card granted to wealthy foreign nationals who make a sizable contribution of at least $1 million to the U.S. government.   

Naturalization requirements 

• Be at least 18 years old at the time of application 
• Show continuous residence in the United States, including at least 2.5 years of physical presence within the required five-year period 
• Demonstrate the ability to read, write, and speak basic English 
• Provide evidence of good moral character 
• Pass the citizenship test (Language and Civics Test, proving knowledge of U.S. history and government) 
• Show commitment to the principles of the U.S. Constitution 
• Complete the process by taking the Oath of Allegiance 

Processing time 

Processing time for a naturalization application takes about 18 to 24 months, and this timeframe includes application submission, biometrics, interview, and the oath ceremony. 

How long do you have to be a permanent resident to qualify for citizenship via standard naturalization? 

To qualify for U.S. citizenship via standard naturalization, you must hold permanent residence status for at least 5 years and be physically present in the United States or its territories for at least 2.5 years out of the 5.  

If one or both of your parents are United States citizens, then you are entitled to automatic U.S. citizenship, even if you were born abroad. You may still be entitled to citizenship if just one of your parents is a U.S. citizen and you were born on or after 14 November 1986. To qualify for this pathway, your parents must have been:  

• Married at the time of your birth 
• The parent who is a citizen must have been resident in the U.S. or any of its territories for at least 5 years before your birth.  
• At least two of these 5 years must have been after their 14th birthday 

If just one of your parents is a U.S. citizen and you were born before 14 November 1986, but after 10 October 1952, then to qualify for citizenship, your parents must have been:  

• Married at the time of your birth 
• The parent who is a citizen must have been resident in the U.S. or any of its territories for at least 10 years at some point in their life. 
• 5 of these years must have been after their 14th birthday 

Documents required 

If you fall into this category, you must submit form N-600, Application for Certificate of Citizenship to begin the process.  

In addition to the official forms, some of the documents you may need to provide are: 

• Proof of physical presence in the U.S. (e.g employment records, educational transcripts, etc.) 
• Birth certificate 
• Civil/legal marriage certificate 
• Evidence of change of name (if applicable) 

Processing time 

This process can be very fast, taking about 4 weeks to a few months for those who qualify, as long as all required documents are provided. This timeline also depends on USCIS processing times.  

Individuals who have served honorably in the U.S. military may be eligible for citizenship through military service and naturalization. Whether you are eligible for a naturalization ceremony or not depends on whether you served during a time of peace or hostility.  

The United States has been in a period of hostility since 11 September 2001. Individuals who serve during this period can apply for expedited naturalization without first becoming permanent residents. On the other hand, those who served during peacetime would need to have served for at least one year before applying and will also need to obtain a Green Card first.  

Requirements 

• Be 18 or older 
• Have served honorably at any time in the U.S. armed forces for a period or periods totaling at least 1 year 
• Demonstrate that if separated from service, you were separated under honorable conditions; 
• Demonstrate knowledge of U.S. history and government via a civics test, unless excepted 
• Complete and submit Forms N-400 and N-426 (if currently serving) 

Processing time 

Eligible applicants can obtain citizenship via naturalization in less than one year, depending on the period they served.  

If you are married to a U.S. citizen, you may be eligible to apply for a Green Card through your spouse, who must file a Form I-130 Petition for an Alien Relative. This is the form that establishes the existing relationship. You must also prove that your relationship is genuine by providing a marriage certificate.  

Individuals who qualify for this pathway are eligible for naturalization application after three years as permanent residents.  

Requirements 

• Have been a lawful permanent resident in the U.S for at least 3 years before the date of your application.  
• Have lived with your spouse during the 3 years before your application 
• Have had a stable residence in the U.S. for at least 3 years before your application 
• Meet all other naturalization requirements such as passing the civics test, showing good moral character, and speaking English. 

Processing time 

The time to process naturalization can be anywhere between 6 to 12 months, depending on USCIS backlog. 

While there is no instant way to become a United States citizen, there are certain steps you can take to avoid delays with your naturalization process. 

• Apply as soon as you are eligible: Submit your naturalization application at the earliest eligible date to help reduce unnecessary waiting time. 
• Ensure your application is complete and accurate: Errors, missing documents, or inconsistencies can lead to delays, requests for evidence, or even denial. 
• Maintain continuous residence and physical presence: Extended trips outside the United States can disrupt your eligibility and delay your application. 
• Prepare thoroughly for the interview and civics test: Being well-prepared reduces the risk of rescheduling or additional review. 
• Monitor USCIS processing times: Staying informed about current timelines helps you plan and respond quickly to any updates or requests. 
• Consider professional guidance: Working with an immigration legal expert can help ensure your application is accurate and complete, reducing the likelihood of delays. 

Citizenship by birth is granted automatically, either by being born in the U.S. or to U.S. parents. On the other hand, naturalized citizens obtain citizenship later through a formal process that includes an application, civic and language tests, and taking the Oath of Allegiance.  

U.S.-born and naturalized citizens share the same rights and responsibilities, including voting, access to federal jobs, and legal protection. The key difference is that only citizens by birth can become President or Vice President in the United States. The proof-of-citizenship documentation is also different. Naturalized citizens receive a Certificate of Naturalization, while born citizens use a birth certificate or Consular Report of Birth Abroad. 

Yes, the U.S. allows dual citizenship, meaning foreign nationals don’t have to give up their original citizenship when they become American citizens. However, to obtain dual citizenship, both countries must allow it.
