How to Apply for U.S. Citizenship: Complete Naturalization Guide


1. What is U.S. Citizenship?

U.S. citizenship grants individuals full rights and responsibilities as Americans, including the right to vote, obtain a U.S. passport, and work without restriction. For most immigrants, U.S. citizenship is obtained through naturalization after meeting residency and other eligibility requirements.


2. Eligibility Requirements for U.S. Citizenship

To become a U.S. citizen through naturalization, applicants must meet the following criteria:

2.1 Continuous Residency

  • Green Card Holders: Must have lived in the U.S. for at least 5 years (or 3 years if married to a U.S. citizen).
  • Continuous Residency Requirement: Applicants should not have any prolonged trips (generally over 6 months) outside the U.S. that break residency continuity.

2.2 Physical Presence

  • Physical Presence: Applicants must have spent at least 30 months (2.5 years) in the U.S. during the 5-year period. For those married to a U.S. citizen, this requirement is 18 months (1.5 years).

2.3 Good Moral Character

Applicants must demonstrate good moral character, typically meaning no serious criminal record or immigration violations.

2.4 English Language and Civics Knowledge

  • English Test: Applicants must show basic proficiency in reading, writing, and speaking English.
  • Civics Test: The test covers U.S. history and government. The applicant must answer 6 out of 10 questions correctly to pass.

2.5 Attachment to U.S. Principles

Applicants must affirm loyalty to the U.S. Constitution and be willing to serve the country if required.


3. Steps to Apply for U.S. Citizenship

Step 1: Complete Form N-400 (Application for Naturalization)

The Form N-400 is the primary application for U.S. citizenship. It can be completed online via the U.S. Citizenship and Immigration Services (USCIS) website or by mail.

Step 2: Pay the Application Fee

  • Standard Fee: $725 (includes $640 for processing and $85 for biometrics).
  • Fee Waivers: Fee reductions or waivers are available for eligible low-income applicants.

Step 3: Attend the Biometrics Appointment

After submitting Form N-400, USCIS will schedule a biometrics appointment where your fingerprints and photos will be taken for a background check.

Step 4: Prepare for the Citizenship Interview and Test

The interview is a significant step in the naturalization process. During the interview, a USCIS officer will review your application and ask questions about your background.

  • English Test: Covers reading, writing, and speaking proficiency.
  • Civics Test: Comprises questions about U.S. history and government. Study resources, including a list of possible questions, are available on the USCIS website.

Step 5: Attend the Naturalization Interview and Take the Test

During the interview, the USCIS officer will review your Form N-400 and ask questions from the civics test. If you pass the tests, you will receive a letter with the results and be invited to the oath ceremony.

Step 6: Attend the Oath of Allegiance Ceremony

The final step in becoming a U.S. citizen is taking the Oath of Allegiance at a naturalization ceremony. Once you take the oath, you will receive a Certificate of Naturalization as proof of your U.S. citizenship.


4. How Long Does It Take to Become a U.S. Citizen?

The naturalization process typically takes 12 to 18 months, though processing times vary based on application volume, location, and individual circumstances.
