Apply for US citizenship: process, requirements and processing time
February 24, 2025
The final step in many immigration journeys is achieving U.S. citizenship. The journey to citizenship can vary, from years spent in nonimmigrant or undocumented status, progressing through permanent residency (green card), to the final step of naturalization.
However, some individuals are citizens from birth. This guide primarily focuses on the naturalization process, while also providing resources for proving citizenship at birth.
Children under the age of 18 who are permanently residing in the United States and otherwise meet the residency tests applicable to adults automatically become U.S. citizens when their parents take the Oath of Citizenship. The child must file an N-600 Certificate of Citizenship Application or a U.S. passport application in order to have proof of citizenship.
Why pursue US citizenship?
While green card holders enjoy many of the same rights as U.S. citizens, significant advantages exist for those who naturalize. Many permanent residents ask “Why should I become a citizen?”.
Here are the key benefits of U.S. citizenship:
Voting Rights and Civic Participation: U.S. citizens can vote in local, state, and federal elections, directly influencing government policies.
U.S. Passport and International Travel: Enjoy visa-free travel to numerous countries with a U.S. passport.
Guaranteed Residency and Protection from Deportation: U.S. citizenship provides permanent residency and protection against deportation, even in cases of criminal conviction (with rare exceptions). To secure lifelong residency in the United States, naturalization is essential. Permanent residents can lose their green cards through prolonged stays abroad. Moreover, a criminal conviction, even for a minor offense, can lead to deportation for permanent residents. However, U.S. citizens are generally protected from deportation, even if they commit crimes.
Access to Government Benefits: Ensure full access to federal and state benefits, which may be restricted for green card holders.
Family Immigration and Sponsorship: Citizenship provides significant advantages in family immigration. U.S. citizens receive priority in sponsoring family members for immigration to the U.S., including spouses, children, parents, and siblings. U.S. citizens over 21 can immediately sponsor spouses, parents and minor children without immediate visa backlogs. While adult children and siblings of US citizens face wait times, these are far shorter than those for green card holders, who cannot sponsor parents or siblings at all.
Federal Employment Opportunities: Many federal jobs, especially in sensitive sectors like defense and energy, require U.S. citizenship.
Jury Duty: Fulfill your civic duty by participating in the U.S. justice system.
Eligibility for Public Office: U.S. citizenship is a requirement for holding many elected positions.
Federal Grants: Increased eligibility for federal grant programs.
Political Contributions: Green card holders living in the U.S. can donate to political campaigns, but the legality of donations from those residing abroad, even temporarily, is unclear.
Key Naturalization Eligibility Categories
The naturalization process involves meeting specific eligibility requirements.
Most applicants fall into these primary categories:
The US citizen spouse must also have been a citizen for at least three years.
Spouse of US Citizen Employed Abroad (INA §319(b)):
This category applies to green card holders whose US citizen spouse is employed overseas in specific qualifying jobs.
This is for people who live outside of the US due to their spouses employment.
Less Common Naturalization Paths:
US military service during times of hostility.
Service as a translator or healthcare professional through programs like MAVNI (when active).
How to apply for US citizenship? The Naturalization Process
To begin your US citizenship application, you’ll need to understand the specific requirements for your eligibility category. The naturalization process typically involves:
Passing the US citizenship test (civics and English).
Attending an interview with USCIS.
What is the earliest I can apply for US citizenship?
You can apply for US citizenship (naturalization) 90 days before meeting the required continued presence of 5 years (general requirement) or 3 years (if you are married to a US citizen). To qualify for early filing, you must meet all other eligibility criteria when you file your form N-400.
To determine your 90-day early filing date, begin by identifying your 5-year or 3-year date as a lawful permanent resident by checking the “Resident Since” date on your Permanent Resident Card.
If you meet all other citizenship requirements, you can submit your naturalization application up to 90 days before your 5th (or 3rd, if married to a US citizen) anniversary as a lawful permanent resident, calculated from the ‘Resident Since’ date on your Green Card.
This section outlines the standard requirements for individuals seeking US citizenship after holding a green card for five years. To qualify under INA 316, you must meet the following:
Age: Must be 18 years or older at the time of filing Form N-400 (Application for Naturalization).
Lawful Permanent Resident (LPR) Status: Must hold a valid green card at the time of application and throughout the naturalization process, with at least five years of LPR status.

Time spent as a conditional permanent resident (CR) counts towards the required residency period for US citizenship eligibility.
