The cost to apply for U.S. citizenship depends on the filing method and your individual circumstances. USCIS filing fees may change periodically, and some applicants may qualify for a reduced fee or fee waiver. Before filing, it is important to verify the current USCIS filing fee and determine whether any exemptions apply to your case.

Most lawful permanent residents may apply after five years, while certain spouses of U.S. citizens may qualify after three years.

Form N-400 is the application used to apply for U.S. citizenship through naturalization.

Processing times vary depending on the USCIS office handling your case and current application volume. In most cases, the citizenship process takes several months from the date of filing until the oath ceremony. Processing times can change throughout the year, so applicants should review current USCIS estimates when preparing to apply.

Some permanent residents may qualify for citizenship after three years instead of five. Generally, this applies to individuals who have been lawful permanent residents for at least three years and have continuously lived with and remained married to a U.S. citizen spouse during that period. Additional eligibility requirements must also be met before applying.

During the citizenship interview, a USCIS officer will review your Form N-400 application and ask questions about your background, travel history, employment history, family information, and eligibility for naturalization. The officer will also administer the English and civics tests unless you qualify for an exemption. At the end of the interview, USCIS may approve your application, continue your case for additional review, or request additional information.

Possibly. Many permanent residents travel internationally and still qualify for citizenship. However, long trips outside the United States may affect eligibility if they interrupt continuous residence or physical presence requirements. Before filing, it is important to review your travel history to determine whether any absences could impact your application.

No. Many individuals successfully apply for citizenship on their own. However, professional assistance may be beneficial if you have a complicated immigration history, extended trips outside the United States, prior arrests, tax issues, previous immigration violations, or concerns about eligibility. Proper preparation can help avoid delays, requests for evidence, and potential complications during the naturalization process.

Applicants should study the official USCIS civics questions covering U.S. history, government, and civic principles. Most applicants must also demonstrate basic English reading, writing, and speaking abilities. Proper preparation is important because USCIS officers often ask follow-up questions during the interview in addition to administering the civics and English tests.
