How the Department of Immigration and Naturalization Services Works

 Navigating the U.S. immigration system can feel complicated, especially when you are applying for permanent residence, citizenship, or another immigration benefit. Many people still use the phrase “Department of Immigration and Naturalization Services” when referring to the government agency responsible for immigration and citizenship matters. Today, the federal agency that handles most of these applications is the U.S. Citizenship and Immigration Services (USCIS), a component of the U.S. Department of Homeland Security. USCIS replaced the former Immigration and Naturalization Service (INS) in 2003.



Understanding how USCIS works can help immigrants, permanent residents, and families better understand what happens after an application is filed and when professional legal assistance may be helpful.

What Is the Department of Immigration and Naturalization Services?

The term “Department of Immigration and Naturalization Services” is commonly used to describe the government system responsible for immigration and naturalization matters. However, the former Immigration and Naturalization Service (INS) no longer exists as a standalone federal agency.

Today, USCIS handles many immigration benefits, including applications for lawful permanent residence, naturalization, employment authorization, family-based immigration benefits, and certain citizenship documents.

For someone seeking U.S. citizenship, understanding the difference between immigration agencies is particularly important. USCIS generally handles applications and petitions for immigration benefits, while other agencies have different responsibilities related to immigration enforcement, border protection, and visa issuance.

Because immigration laws and procedures can be complicated, applicants should carefully review their circumstances before submitting an application.

How Does USCIS Process Immigration Applications?

USCIS generally follows a structured process when reviewing immigration applications. The exact procedure depends on the type of benefit being requested, but many cases involve several common stages.

1. Determining Eligibility

The first step is determining whether you qualify for the immigration benefit you want to request.

For naturalization, eligibility can depend on factors such as lawful permanent resident status, length of residence, physical presence, good moral character, English-language requirements, and knowledge of U.S. history and government. USCIS identifies these requirements as part of the naturalization process.

For many permanent residents, the standard naturalization route involves five years as a lawful permanent resident. Certain applicants married to U.S. citizens may qualify under a three-year rule if they meet the applicable requirements.

Because individual circumstances can affect eligibility, consulting a naturalization attorney New York residents can work with may be useful before filing.

2. Preparing and Filing the Application

Once eligibility has been established, the next step is preparing the appropriate application and supporting documentation.

For most people applying for citizenship through naturalization, the primary application is Form N-400, Application for Naturalization. USCIS recommends reviewing the form instructions, gathering supporting evidence, completing the application accurately, and submitting the required filing fee or requesting an applicable fee waiver or reduction.

Mistakes, missing information, inconsistent answers, or incomplete documentation can create unnecessary complications. This is one reason applicants may choose to work with a citizenship lawyer who can review their circumstances and application before filing.

3. Biometrics and Background Checks

Depending on the case, USCIS may require biometrics such as fingerprints, a photograph, and a signature.

Applicants who receive a biometrics appointment notice should attend at the scheduled time and location. USCIS may use fingerprints for background checks as part of the application process.

Not every applicant will experience exactly the same process, so it is important to follow the instructions provided by USCIS for the individual case.

What Happens During a Naturalization Interview?

The naturalization interview is an important part of the citizenship process.

During the interview, a USCIS officer reviews the applicant's Form N-400 and asks questions about the applicant's background and application. Eligible applicants generally also complete the required English and civics testing unless an exemption, exception, or accommodation applies.

The English portion can involve reading, writing, and speaking. The civics portion evaluates knowledge of U.S. history and government.

Applicants should carefully review their N-400 before the interview because they need to be prepared to answer questions accurately and consistently.

A naturalization lawyer New York applicants trust can help them understand what to expect, review their application, identify potential concerns, and prepare for the interview.

Understanding the Laws of Naturalization of Foreigners

The laws of naturalization of foreigners establish the requirements and procedures through which eligible immigrants can become U.S. citizens.

Naturalization is not automatic for every permanent resident. Applicants generally must satisfy several legal requirements before they can become citizens. These can include residency, physical presence, good moral character, English and civics requirements, and an oath of allegiance.

However, exceptions and special rules may apply to certain applicants. For example, some applicants may qualify under different provisions based on marriage to a U.S. citizen, military service, disability-related accommodations, or other circumstances.

This is why applicants should not assume that another person's citizenship experience will be identical to theirs.

What Happens After the Interview?

After the naturalization interview, USCIS may approve the application, request additional evidence, continue processing, or take another action depending on the circumstances.

If the application is approved, the final step is generally the Oath of Allegiance. A person does not become a U.S. citizen through naturalization until completing the required oath at the naturalization ceremony. USCIS then provides a Certificate of Naturalization.

This final stage is an important milestone because it formally completes the naturalization process.

When Should You Consider an Immigration Attorney?

Not every immigration application requires an attorney. However, professional legal guidance can be especially valuable when an applicant has a complicated immigration history or is uncertain about eligibility.

Potential issues can include:

  • Long or frequent trips outside the United States

  • Previous immigration violations

  • Criminal history

  • Questions about good moral character

  • Previous applications or inconsistent immigration records

  • Problems involving permanent resident status

  • Difficulty understanding eligibility requirements

  • Requests for evidence from USCIS

  • Previous naturalization application problems
