Key Takeaways

Understanding the requirements for American citizenship matters before you spend time, money, and energy preparing Form N-400. Naturalization is a major step, but eligibility comes first.
In Part 1, I discussed the proposed naturalization N-400 form fee increase. In Part 2, I explained the benefits of citizenship. In this article, I want to explain what USCIS generally reviews before approving a permanent resident for citizenship.
My name is Taghrid G. Hassan, Esq., and I am the founder of Hassan Law P.A. I have practiced family and immigration law for nearly 20 years.
As a Sunrise immigration lawyer, I help clients in Sunrise, Plantation, Weston, Davie, Tamarac, Lauderhill, Coral Springs, Fort Lauderdale, Pembroke Pines, Hollywood, and nearby Broward County communities review their eligibility before filing.
Why Eligibility Review Comes First
If becoming a U.S. citizen is your goal, do not treat Form N-400 like a simple renewal.
USCIS does not only review your name, address, and Green Card. It may review your immigration history, travel, criminal record, tax compliance, family obligations, and answers on prior applications.
That does not mean every issue prevents approval. It means you should understand the issue before filing.
Do not file first and hope USCIS misses a problem.
Review the facts before the application goes in.
Basic Naturalization Requirements
The basic requirements for American citizenship generally include several parts.
- Be at least 18 years old
- Be a lawful permanent resident
- Hold a Green Card for at least 5 years in most cases
- Qualify under the 3-year rule in some marriage-based cases
- Meet continuous residence requirements
- Meet physical presence requirements
- Live in the state or USCIS district for at least 3 months before filing
- Show good moral character
- Meet English and civics requirements unless an exception applies
- Support the principles of the U.S. Constitution
- Take the Oath of Allegiance
USCIS lists the general 5-year naturalization requirements as including 30 months of physical presence, continuous residence, basic English, civics knowledge, and good moral character. You can review the official USCIS naturalization eligibility information.
The 5-Year Rule for Permanent Residents
For many applicants, becoming a U.S. citizen starts with the 5-year rule.
You generally must have been a lawful permanent resident for at least 5 years before filing. You must also show that you kept continuous residence in the United States during that period.
Physical presence is different. It looks at the actual time you spent inside the United States. Under the common 5-year rule, applicants generally need at least 30 months of physical presence during the 5 years before filing.
Long trips can cause problems. Frequent travel can also raise questions, even if no single trip was very long.
The 3-Year Rule for Some Spouses of U.S. Citizens
Some permanent residents may qualify after 3 years if they are married to a U.S. citizen and meet the marriage-based naturalization rules.
This path has details that matter. The applicant must generally meet requirements involving permanent residence, marital union, residence with the U.S. citizen spouse, and the spouse’s citizenship.
It is not automatic. A person can be married to a U.S. citizen and still need to review travel, taxes, good moral character, and prior immigration history.
Continuous Residence and Physical Presence
Continuous residence looks at where your main home has been. Physical presence counts the days you were actually inside the United States.
A long trip abroad may affect continuous residence. Multiple trips may affect physical presence. This is common for families who travel to care for relatives, manage property overseas, or keep business ties outside the United States.
In Sunrise and surrounding Broward communities, many families have strong ties abroad. Before filing, I like to review travel history closely. Dates matter.
A Sunrise immigration lawyer like myself can help you calculate travel time and spot trips that may create questions.
Good Moral Character
Good moral character is one of the most important requirements for American citizenship.
USCIS may review arrests, charges, convictions, probation, taxes, child support, false statements, and other conduct. Some issues create automatic problems. Others require a closer case-by-case review.
USCIS guidance explains that good moral character is evaluated during the required statutory period and may also involve conduct outside that period in some situations. You can review the official USCIS good moral character guidance.
If you have ever been arrested, cited, charged, or convicted,
get certified records before filing Form N-400.
English and Civics Requirements
Most applicants must show basic English skills and knowledge of U.S. history and government.
The English portion generally includes:
- Speaking during the interview
- Reading one sentence
- Writing one sentence
The civics portion tests knowledge of U.S. government and history.
Some applicants qualify for language exceptions based on age and years as a perma
Red Flags That Need Legal Review
Some issues deserve legal review before filing.
These include:
- Criminal history
- Extended travel outside the United States
- Unpaid taxes
- Failure to pay court-ordered child support
- Prior immigration fraud or misrepresentation
- False claims to U.S. citizenship
- Conflicting information in older immigration filings
A red flag does not always mean you cannot apply. It means you should understand the risk first.
Because naturalization is part of immigration law, the safest time to identify a problem is before USCIS reviews your case.
Local Planning for Sunrise and Nearby Cities
Many of my clients live or work near Sawgrass Mills, Sawgrass International Corporate Park, Amerant Bank Arena, Sunrise Lakes, Welleby, Plantation, Weston, Davie, Tamarac, Lauderhill, Coral Springs, Fort Lauderdale, Pembroke Pines, and Hollywood.
Their questions are practical. Can a trip affect eligibility? Can an older parent take the test in another language? Can a past mistake on an immigration form cause problems now? Can citizenship help with family petitions later?
As a Sunrise immigration lawyer, I can connect those personal facts to the naturalization rules.
