If you’re applying for U.S. citizenship in 2026 or beyond, pay close attention. Every year, hundreds of applicants are denied citizenship because of three common mistakes—and they have nothing to do with failing the civics test.
In this video, I’ll explain exactly what those three mistakes are. These are serious issues that can cause a USCIS officer to stop your interview, close your case, and ultimately deny your citizenship application.
What are the requirements to apply for U.S. citizenship?
Generally, a green-card holder must meet these requirements:
- Be at least 18 years old when filing Form N-400.
- Have been a lawful permanent resident for at least 5 years. There is a separate 3-year rule for certain applicants who obtained their green card through marriage to a U.S. Citizen
- Maintain continuous residence in the United States during the required 5-year or 3-year period. Long trips outside the U.S., especially trips of 6 months or longer, can create problems.
- Be physically present in the United States for at least 30 months of the previous 5 years. Under the 3-year marriage rule, the requirement is generally at least 18 months.
- Demonstrate good moral character. USCIS generally examines at least the statutory 5-year or 3-year period, although conduct from earlier periods can also be taken into account
- Demonstrate basic English ability by speaking, reading, and writing English, unless you qualify for an age/residency or disability exception.
- Pass the U.S. civics test, unless an exception applies. For N-400 applications filed on or after October 20, 2025, USCIS uses the 2025 naturalization civics test.
