U.S. Citizenship & Naturalization in Los Angeles and Southern California

Becoming a U.S. citizen is one of the most significant milestones in an immigrant’s life. It brings the right to vote, the ability to petition for a wider range of family members, protection from deportation, and the security of knowing your status in this country is permanent.

The naturalization process involves a formal application, a background check, an English and civics test, and an interview with USCIS. While many people navigate it successfully on their own, working with an immigration attorney ensures your application is complete, your eligibility is confirmed before filing, and you are fully prepared for every step, including the interview.

The Law Office of Martín O’Hara assists lawful permanent residents throughout Southern California with naturalization applications, citizenship through parents, and USCIS interview preparation.

Paths to U.S. Citizenship

There are several ways a person may become a U.S. citizen. The most common is naturalization, which is the formal legal process for lawful permanent residents. Others may already be citizens through their parents without realizing it.

Naturalization. The standard path for green card holders who meet the residency, language, and character requirements. Most applicants must hold a green card for five years before applying, though spouses of U.S. citizens may qualify after three years.

Citizenship Through a U.S. Citizen Parent. Some people born outside the United States to a U.S. citizen parent are U.S. citizens at birth (or became citizens automatically after birth and before turning 18) without ever going through the naturalization process. If you believe this may apply to you, an attorney can review your family history and determine whether you may already be a citizen.

Citizenship Through Military Service. Members of the U.S. Armed Forces and certain veterans may qualify for naturalization under expedited rules, including during periods of hostilities when the normal residency requirements are reduced or waived.

Naturalization Requirements: The Standard Five-Year Path

To qualify for naturalization as a lawful permanent resident of at least five years, you generally must:

Be at least 18 years old at the time of filing
Have held a green card for at least five continuous years
Have lived continuously in the United States for at least five years immediately before filing
Have been physically present in the U.S. for at least 30 months out of those five years
Have lived for at least three months in the state where you are filing
Demonstrate good moral character for the five years before filing
Be able to read, write, and speak basic English
Pass the U.S. civics test (100 questions covering U.S. history and government)
Show attachment to the principles of the U.S. Constitution
Take the Oath of Allegiance at a naturalization ceremony

The Three-Year Path for Spouses of U.S. Citizens

If your green card was obtained through marriage to a U.S. citizen and you are still married to and living with that same citizen spouse, you may be eligible to apply for naturalization after only three years, rather than five. The requirements are similar but adjusted:

Hold a green card for at least three continuous years
Have been living in marital union with your U.S. citizen spouse throughout those three years and up through the naturalization interview
Have been physically present in the U.S. for at least 18 months out of those three years
Meet the English, civics, moral character, and residency requirements described above

This path can significantly shorten the time to citizenship for eligible spouses, but the marriage must be genuine and ongoing. USCIS scrutinizes these cases very carefully.

What to Expect in the Naturalization Process

Step 1: Eligibility Review. Before filing anything, we review your complete immigration history, any criminal record, travel history, and tax filing record to confirm you meet all requirements. Issues discovered after filing are much harder to address than those identified beforehand.

Step 2: Application Preparation and Filing. We prepare your Form N-400 (Application for Naturalization) and all required supporting documentation. Every question on the N-400 is answered carefully and completely because USCIS officers will review the application in detail at your interview.

Step 3: Biometrics Appointment. After filing, USCIS schedules a biometrics appointment to collect your fingerprints, photograph, and signature for a background check. This is straightforward and typically takes less than 30 minutes.

Step 4: The USCIS Interview. A USCIS officer reviews your application, tests your English reading and writing, administers the civics test (you must answer 6 out of 10 questions correctly), and asks questions about your background and application. We prepare you thoroughly for this interview so you know exactly what to expect.

Step 5: The Oath of Allegiance. If your application is approved, you are scheduled for a naturalization ceremony where you take the Oath of Allegiance and receive your Certificate of Naturalization. This is the moment you officially become a U.S. citizen.

Common Issues That Can Complicate a Naturalization Application

Naturalization is not automatic even for long-time green card holders. Several factors can delay or derail an application:

Gaps in Continuous Residence. Extended trips outside the United States can break the continuous residence requirement. Absences of more than six months in a single trip are presumed to have disrupted continuous residence, and absences of more than one year almost always do. We review your travel history carefully before filing.

Criminal History. Any arrest, charge, or conviction (even for minor offenses) must be disclosed on the N-400 and can affect your good moral character determination. This includes expunged convictions in many cases. We review your record before filing to assess the risk and determine how to present the information accurately.

Tax Issues. Failure to file taxes, claiming non-resident status on tax returns, or other tax irregularities can raise questions about good moral character or continuous residence. We flag these issues before they become problems at the interview.

Prior Immigration Violations. Certain prior immigration violations (including periods of unlawful presence, prior removal orders, or fraud in obtaining the green card) can affect naturalization eligibility. These require careful legal analysis before an application is filed.

Frequently Asked Questions

How long does the naturalization process take?

Processing times vary by USCIS field office and can range from several months to over a year. The Los Angeles area USCIS offices have historically had significant backlogs. We can give you a realistic estimate based on current processing times at the office handling your application.

Do I need a lawyer to apply for naturalization?

You are not required to have an attorney. However, an attorney is particularly valuable if you have any criminal history, tax issues, extended international travel, gaps in employment, prior immigration violations, or any other factor that could complicate your application or raise questions at the interview. A denial or referral to immigration court is far more costly than getting it right the first time.

What happens if I fail the civics or English test?

If you fail either test at your interview, USCIS will schedule a second interview and give you another opportunity to pass. If you fail the second time, your application is denied and you must refile and pay the filing fee again. We prepare clients thoroughly to avoid this outcome.

Can I apply for naturalization if I have a criminal record?

It depends on the nature of the conviction and when the conviction occurred. Certain convictions (including “aggravated felonies”) permanently bar naturalization. Others create a temporary bar or require a waiting period. Some may not affect eligibility at all. This requires a careful legal analysis before any application is filed.

Will my children automatically become citizens when I naturalize?

Children under 18 who are lawful permanent residents may automatically acquire U.S. citizenship when a parent naturalizes, depending on the child’s age, custody arrangements, and residency. This is called “derivative citizenship.” We can review whether your children qualify.

I was born outside the U.S. to a U.S. citizen parent. Am I already a citizen?

Possibly. Whether you acquired citizenship at birth depends on the law in effect at the time of your birth, your parent’s citizenship status, and how long your parent lived in the United States before your birth. This analysis can be complex, particularly for older cases. We can review your family history and determine whether you may already be a U.S. citizen.
