Applying for U.S. citizenship is an exciting milestone, but it can also be daunting. For many, the path to citizenship represents security, stability, and new opportunities. However, receiving a denial letter instead of an approval can be frustrating and disheartening. Knowing why applications are denied can help you identify common pitfalls and better prepare for a successful outcome. Below, we’ve outlined some of the top reasons why citizenship applications are denied, along with tips to improve your chances of success.
One of the most preventable reasons for denial is submitting an incomplete or incorrect application. U.S. Citizenship and Immigration Services (USCIS) requires all information to be filled out correctly on Form N-400 (the naturalization application). Missing sections, outdated forms, or inconsistencies between your application and supporting documents can result in rejection.
Applicants must demonstrate continuous residence and physical presence in the U.S. before applying for naturalization. Generally, you need to have lived in the U.S. continuously for at least 5 years (or 3 years for those married to U.S. citizens) and spent at least 30 months physically present in the country during that time.
A two-part exam tests your knowledge of English and U.S. civics. While USCIS offers study materials, many applicants fail due to insufficient preparation or test anxiety.
Applicants must prove “good moral character” throughout the required residency period. Certain criminal activity or behaviors, such as fraud, unpaid taxes, or failure to support dependents, can lead to a denial.
Missing a biometrics appointment, interview, or other USCIS-required appointments can delay your application or result in denial. USCIS requires all applicants to complete each step of the process on time.
Applicants must demonstrate basic proficiency in English unless they qualify for specific exemptions. Lack of communication skills during the interview may hinder the process.
Citizenship applications require various documents, such as tax returns, marriage certificates, and proof of residency. Submitting outdated, missing, or unverifiable documents can lead to complications.
