This guide explains US citizenship requirements in clear, simple language so you can confidently understand who is eligible to apply for U.S. citizenship and how to prepare successfully.

This article is written especially for immigrants and English-language learners, with practical examples and plain explanations. Throughout this guide, we will clearly explain US citizenship requirements, eligibility rules, history, and helpful tips, plus how the BeCitizen App can support you at every step.

What Are US Citizenship Requirements?

At its core, US citizenship requirements are the legal rules set by the U.S. government that determine who may apply for citizenship through naturalization. To apply for U.S. citizenship, you must meet all US citizenship requirements established by U.S. Citizenship and Immigration Services (USCIS). While every case is unique, most applicants must meet the same basic US citizenship requirements, which we explain below.

Basic US Citizenship Requirements for 2025

The main US citizenship requirements include:

1. Lawful Permanent Resident (Green Card Holder)

One of the most important US citizenship requirements is lawful permanent residence.

You must:

• Hold a Green Card

• Maintain continuous residence in the U.S.

Most applicants must meet this US citizenship requirement for:

• 5 years (standard rule), or

• 3 years if married to a U.S. citizen

2. Continuous Residence and Physical Presence

Another key part of US citizenship requirements is time spent in the United States.

You must:

• Live continuously in the U.S.; trips outside the United States for more than 6 consecutive months may disrupt continuous residence.

• Be physically present for at least 30 months out of 5 years (or 18 months out of 3 years)

Extended travel abroad can affect your US citizenship requirements, which is why tracking travel history is essential.

3. USCIS district Residency Requirement

Among standard US citizenship requirements, applicants must:

• Live in the same USCIS district for at least 3 months before applying

This ensures your application is processed locally.

4. Good Moral Character

Good moral character is a critical part of US citizenship requirements.

USCIS reviews:

• Criminal history

• Taxes

• Child support obligations

• Honesty in past immigration applications

Even minor issues can affect US citizenship requirements, so preparation matters.

English and Civics Test Requirements

Most applicants must meet testing-related US citizenship requirements, including:

English Language Requirement

You must demonstrate:

• Basic English reading

• Writing

• Speaking and Comprehension ability

Civics Test Requirement

You must answer questions about:

• U.S. history

• Government

• Constitution

These testing US citizenship requirements are often the most stressful—but they are very manageable with the right preparation tools.

This is where the BeCitizen App becomes especially valuable. It offers:

• ESL-friendly lessons

• Real USCIS-style practice questions

Exemptions and Special US Citizenship Requirements

Some applicants qualify for exceptions to US citizenship requirements, especially related to age and disability.

You may qualify for exemptions if:

• You are 50/20 or 55/15 (age + years as Green Card holder)

• You have a qualifying medical condition (Form N-648)

Understanding these special US citizenship requirements can remove unnecessary fear and confusion.
