Before a USCIS officer asks about the Declaration of Independence, a candidate must go through an entire process that begins with a single form and can last from several months to over a year. For many Poles with a green card, it is this path – and not the exam itself – that is the biggest unknown. Let’s try to organize it.
What it starts with: Form N-400
At the heart of the entire process is Form N-400, the “Application for Naturalization.” This is the first official step for a green card holder who wants to become a US citizen. The application can be submitted electronically by creating an account on the myUSCIS portal or traditionally, on paper. The online version is usually more convenient and cheaper – USCIS offers a discount for it. The form is detailed: it asks about residence history, travel, employment, tax filings, potential criminal record, and affiliations. Any inaccuracy can delay the case, so it’s worth filling it out carefully, and if in doubt, seek legal assistance.
Who can apply
Before even reaching for the form, you need to check if you meet the conditions. The basic rule is that a person who has been a permanent resident of the USA for at least 5 years, meaning they have held a green card, can apply for citizenship. For spouses of American citizens, this period is shortened to 3 years. Importantly, the application can be submitted up to 90 days before the required residency period is reached – this is a popular way to speed up the entire procedure slightly. However, it must be remembered that early submission only applies to the continuous residency requirement; other conditions must be met on the day the form is submitted.
However, the length of residency alone is not everything. You also need to demonstrate so-called continuous residence and physical presence in the country – under the five-year rule, at least thirty months of physical presence in the USA is required. Here lies a pitfall that many forget: a single trip outside the USA lasting six months or longer can create a presumption of breaking continuous residence and lead to its challenge, and a trip lasting a year or longer is even riskier. For Poles who frequently travel to their home country – to visit family, deal with inheritance or property matters – this is a real risk worth considering in advance.
Five stages on the path to the oath
Although every case is different, the naturalization process can be presented as five consecutive steps. Knowing them helps to become familiar with what, from a distance, looks like a bureaucratic labyrinth.
1. Filing Form N-400
You fill out and submit the form along with the required fee and documents – including a copy of your green card and, if necessary, two photos compliant with USCIS guidelines.
2. Biometrics
USCIS schedules an appointment for fingerprinting and biometric data collection, which is used to verify the candidate in databases. For most applicants today, the biometric fee is already included in the main fee.
3. Interview and exam
This is a crucial moment: an interview with a USCIS officer, during which the information from the application is verified, and the candidate takes an exam on civics knowledge and English language proficiency – in speaking, reading, and writing. This is the famous test we wrote about separately: individuals filing Form N-400 on or after October 20, 2025, will take the 2025 version of the civics test, which includes 20 questions from a pool of 128, with a requirement of 12 correct answers.
4. Decision
After the interview, USCIS issues a decision – approving, denying, or indicating the need for additional documents. In case of denial, there are appeal options.
5. Ceremony and oath
The final step is the solemn oath of allegiance to the United States during the naturalization ceremony. Only after taking the oath does the candidate become a full citizen and is entitled to apply for an American passport.
How much does it cost, and how long does it take
The fee for Form N-400 depends on how the application is submitted and the applicant’s individual situation. USCIS offers lower fees for online filings than for paper filings, as well as the possibility of a reduced fee or a complete fee waiver in specific cases. Since rates can be adjusted, always check the current amount using the official fee calculator on the USCIS website before sending documents – this helps avoid rejection of the application due to an incorrect fee. Importantly, the system provides for waivers: individuals with lower incomes can apply for a reduced fee or a complete waiver (Form I-912), and soldiers serving during specific periods are exempt.
As for time, according to USCIS data, the median processing time for ordinary N-400 cases in fiscal year 2026, based on data up to the end of April 2026, was approximately 6.5 months – although the time for a specific case depends on the local office, the workload of the agency, and individual circumstances. In practice, the entire process – from filing the form to the ceremony – can take from several months to over a year, and longer in more complex or overloaded locations. It is worth being patient and not planning international travel until biometrics or an interview might be scheduled.
The most common pitfalls Poles fall into
Experience from many immigration law firms shows that problems rarely concern the exam itself – with proper preparation, most people pass it. Difficulties arise elsewhere: from interrupted continuous residence after a long trip to Poland, from undisclosed tax problems in the past, from alimony arrears, or from minor criminal matters that the applicant forgot to mention. The requirement of “good moral character” may sound vague, but in practice USCIS meticulously reviews the candidate’s history. Therefore, with any complications – travel, taxes, legal history – it is worth consulting a specialist before submitting the application, rather than waiting until problems arise.
Don’t go it alone if the case is complicated
For a person with a clean residency history and settled taxes, naturalization can be a tedious but predictable process. However, if there are question marks in your situation – long trips, arrears, divorce, or property matters on both sides of the ocean – professional help can save months and unnecessary stress. Polish-American immigration lawyers can assess the legal situation and prepare a case strategy, and professional translators can assist with translating required documents for USCIS.
