Becoming a U.S. citizen is the goal for many of Florida’s green-card holders, and for good reason: citizens can vote, hold a U.S. passport, petition for more relatives, and cannot be deported. This guide explains naturalization — the process of applying for citizenship with Form N-400 — and the core requirements for Florida residents in Miami, Tampa, Orlando, Jacksonville, and beyond.

Citizenship is governed by federal law: the Immigration and Nationality Act (INA), 8 U.S.C., and 8 C.F.R., administered by U.S. Citizenship and Immigration Services (USCIS). No Florida statute grants citizenship. This is general information, not legal advice; consult an immigration attorney about your own eligibility.

The basic eligibility requirements

Most people naturalize under INA § 316 (8 U.S.C. § 1427). The general requirements are:

  • Age and status: at least 18 years old and a lawful permanent resident (green-card holder).
  • Time as an LPR: generally five years as a permanent resident — or three years if you have been married to and living with the same U.S.-citizen spouse for those three years (INA § 319, 8 U.S.C. § 1430).
  • Continuous residence: you must have continuously resided in the U.S. during that period. Long trips abroad — especially six months or more — can break continuity.
  • Physical presence: you must have been physically present in the U.S. for at least half of the required period (about 30 months out of five years, or 18 months out of three).
  • Residence in the district: you must have lived in the state or USCIS district (here, Florida) for at least three months before filing.
  • Good moral character (GMC): required for the relevant period, usually the statutory five or three years up to the oath.
  • English and civics: you must demonstrate an ability to read, write, and speak basic English and pass a U.S. history and government (civics) test.
  • Attachment to the Constitution and willingness to take the Oath of Allegiance.

The application: Form N-400

You apply by filing Form N-400, Application for Naturalization, with USCIS (online or by mail). A Florida applicant then attends a biometrics appointment and an interview at a USCIS field office such as Miami (Kendall), Tampa, Orlando, or Jacksonville. At the interview the officer reviews the application, tests English and civics, and decides the case. If approved, you take the Oath of Allegiance at a ceremony — often a large group event in Florida — and receive your Certificate of Naturalization.

Good moral character — what can derail a case

Good moral character is one of the most heavily scrutinized requirements. Some issues are permanent bars (for example, a murder conviction or an aggravated felony after 1990). Others are conditional bars during the statutory period — certain crimes, fraud, false testimony to gain an immigration benefit, unlawful voting, failure to pay child support, or failure to file taxes. Because many Florida criminal offenses can also affect immigration status, anyone with an arrest or conviction should consult an attorney before filing the N-400; in some cases applying can even expose an applicant to removal.

The English and civics tests

The English requirement covers basic reading, writing, and speaking; the speaking ability is assessed through the interview itself. The civics test asks questions about U.S. history and government. Limited exemptions and accommodations exist — for example, older applicants with long residence may qualify for an English exemption (the “50/20” and “55/15” rules), and a medical disability waiver (Form N-648) may excuse the testing requirements for qualifying applicants. USCIS publishes current study materials; the test content and format can change, so use the official version for your filing.

Already a citizen? Acquisition and derivation

Some people are U.S. citizens without ever filing an N-400. Acquisition at birth can pass citizenship to a child born abroad to a U.S.-citizen parent who meets residence requirements. Derivation under the Child Citizenship Act (INA § 320, 8 U.S.C. § 1431) can make a child a citizen automatically when a parent naturalizes, if the child is a green-card holder under 18 living in the parent’s custody. If this applies to you, you may apply for a Certificate of Citizenship (Form N-600) rather than naturalize.

Benefits and consequences of citizenship

Naturalized citizens can vote, get a U.S. passport, sponsor more family members (including parents and siblings), access certain jobs and benefits, and — importantly — cannot be placed in removal proceedings. The U.S. permits dual citizenship, though your country of origin’s rules may differ. Once you naturalize, the financial-support obligation tied to a sponsor’s affidavit generally ends.

How this fits the bigger picture

Most people reach naturalization after first getting a green card — often through family; see family-based green cards in Florida — or through employment; see work visas and employment immigration in Florida. For the full overview, see our complete guide to immigration law in Florida.

Frequently asked questions

How long must I be a green-card holder before naturalizing?

Generally five years as a lawful permanent resident, or three years if you have been married to and living with the same U.S.-citizen spouse for those three years. You can usually file the N-400 up to 90 days before reaching the required time.

Will a Florida criminal record stop me from naturalizing?

It depends on the offense and timing. Some convictions are permanent bars; others are conditional bars during the statutory good-moral-character period; and some can even trigger removal. If you have any arrest or conviction, consult an immigration attorney before filing the N-400.

Do I have to take the English and civics tests?

Usually yes, but exemptions exist. Older applicants with long residence may be exempt from English (the 50/20 and 55/15 rules), and a medical disability waiver (Form N-648) may excuse the tests for qualifying applicants. Use the current official USCIS study materials.

Does USCIS change naturalization fees and test content?

Yes. USCIS adjusts filing fees periodically and can update the civics test and form editions. Always confirm the current fee, form edition, and study materials on the official USCIS website before filing your N-400.

Find a Florida immigration attorney

Naturalization is often straightforward, but issues like long trips abroad, tax problems, or any criminal history can turn a routine N-400 into a serious risk. A licensed Florida immigration attorney can review your eligibility, flag problems before you file, and prepare you for the interview at a Miami, Tampa, Orlando, or Jacksonville field office. Consider consulting one about your specific situation.
