U.S. citizenship is the highest legal status in the country. For most adult foreign nationals, there is only one path: first obtain a green card, then go through naturalization by filing Form N-400, attending an interview, passing the U.S. citizenship test, and taking the oath. However, there are other grounds as well: birth in the United States, citizenship through a parent, automatic acquisition of status by a child before the age of 18, military service, and certain separate procedures. There is no direct route to “buy U.S. citizenship in 2026”: even investment programs lead first to immigration status, not directly to an American passport.
Why is this topic so popular? Because U.S. citizenship gives what neither a temporary visa nor even permanent resident status can provide: full political status, the right to vote, a U.S. passport, stronger protection of the right to live in the country, access to certain federal jobs, and broader family-based opportunities. Put simply, a green card is the closest American equivalent to permanent residence, while temporary visas grant only temporary immigration status, not citizenship.
In this article, we will look at who may qualify for U.S. citizenship, what legal pathways exist to obtain it, what requirements applicants must meet, how long the process takes, and how much it costs. We will also review the application process, the specifics of dual citizenship, and the most common mistakes. All information is cлurrent as of 2026 and is based on the rules and practice in force at this time.
Benefits of U.S. Citizenship
What a U.S. passport provides in practice:
- The right to live in the country without the risk of losing status due to long periods spent abroad, as can happen with permanent residents.
- Political rights, including the ability to vote in federal elections, apply for certain government positions, and use a U.S. passport as official proof of status. After naturalization, a U.S. passport can be obtained through the Department of State, and in cases of dual citizenship, entry to and exit from the United States must be done using the American passport.
- Expanded family immigration opportunities. A U.S. citizen can make broader use of family-based immigration options. For example, only citizens aged 21 and older can file petitions for their parents. In addition, in certain cases, a child automatically becomes a citizen after a parent’s naturalization, provided legal requirements are met.
- Access to certain federal grants, scholarships, and government support programs. However, it is important not to confuse facts with myths. Pensions and many social benefits in the United States depend not only on citizenship but also on work history, age, income level, state of residence, and the specific program. The same applies to healthcare: government insurance programs for low-income individuals, the elderly, and children, as well as insurance plans offered through public platforms, each have their own eligibility rules.
In other words, U.S. citizenship strengthens legal stability but does not replace work history or guarantee “automatic free healthcare.”

Who Can Qualify for U.S. Citizenship
Under U.S. law, the following categories of individuals may qualify for U.S. citizenship: those born in the United States and subject to its jurisdiction, children who acquired citizenship through their parents, permanent residents who complete the naturalization process, spouses of U.S. citizens under a simplified procedure, and certain applicants through military service. For most adult foreign nationals, the standard path is naturalization after obtaining a green card.
It is also important to address common phrases such as “U.S. citizenship by ancestry” or obtaining citizenship through repatriation. The United States does not have a broad, classical repatriation system based on distant ancestry such as grandparents or great-grandparents. Having distant American roots alone does not grant U.S. citizenship. In practice, only citizenship transmission from a U.S. citizen parent under the rules in force at the time of birth, or specific child-related procedures such as Forms N-600 or N-600K, apply.
If a child is born outside the United States, they may acquire citizenship at birth through a U.S. citizen parent. However, important factors include the parents’ marital status, the child’s date of birth, and the physical presence of the U.S. citizen parent in the United States prior to the child’s birth. In a typical case with one U.S. citizen parent, the rule requires at least 5 years of physical presence in the United States, including 2 years after the age of 14. Proof is usually provided through a Consular Report of Birth Abroad (CRBA) and/or a U.S. passport. If a person already holds a valid U.S. passport, obtaining a separate Certificate of Citizenship (Form N-600) is generally not required.
There is also a pathway for children after birth. Under the Child Citizenship Act, a child may automatically become a U.S. citizen before the age of 18 if they are a lawful permanent resident, reside in the United States under the legal and physical custody of a U.S. citizen parent, and meet all legal requirements. For children who permanently reside outside the United States, there is a separate procedure through Form N-600K; in some cases, it allows reliance on the physical presence of a U.S. citizen grandparent.
The marriage-based pathway is one of the most commonly misunderstood. Marriage to a U.S. citizen does not automatically grant citizenship. First, the foreign spouse must obtain permanent resident status, and only afterward may they apply for citizenship under the reduced timeline—after 3 years as a lawful permanent resident and 3 years of marriage to a U.S. citizen. The spouse must remain a U.S. citizen until the oath ceremony.
Special provisions apply to military personnel. For those who serve honorably, certain requirements related to residence and physical presence may be reduced or waived, and government filing fees under these provisions are typically not charged.
Obtaining U.S. citizenship through investment is not a direct purchase of a passport. In the traditional route, investors apply through the EB-5 program, where the investment must be made in a new commercial enterprise and create at least 10 full-time jobs. As of 2026, USCIS also provides Form I-140G under the Gold Card program, but this is a petition for an immigrant visa, not immediate citizenship. The same principle applies to individuals with extraordinary achievements in sports, science, or other fields: such candidates typically first obtain an immigration pathway (for example, EB-1A or NIW) and only later apply for naturalization under standard rules.
Giving birth in the United States may grant citizenship to the child by right of birth, but it does not automatically provide citizenship or a green card to the parents. As of 2026, the basic principle of birthright citizenship remains in effect: Executive Order 14160, which aimed to limit it, has not come into force, as its implementation has been blocked by courts and the legal dispute has not yet been resolved.
How to Obtain U.S. Citizenship: All Legal Pathways
In simplified terms, the main pathways are:
- by birth in the United States,
- by descent from a U.S. citizen parent,
- through naturalization after obtaining lawful permanent resident (LPR) status,
- through marriage to a U.S. citizen under the reduced 3-year pathway,
- through military service,
- through specific child-related procedures under INA Sections 320/322.
For most readers, the question “how to obtain U.S. citizenship” comes down to one scenario: first obtaining an immigration status, then living in the country for the required period, and only afterward applying for naturalization through Form N-400.
The primary law governing U.S. citizenship is the Immigration and Nationality Act (INA), while citizenship by birth is also based on the U.S. Constitution and court practice. Therefore, it is important to rely not on reviews or advertising promises, but on your legal basis and the official USCIS process.
The Process of Obtaining U.S. Citizenship
First, check whether you are already a U.S. citizen. This is an important step: many people apply for naturalization even though they actually need not Form N-400, but rather a Consular Report of Birth Abroad (CRBA), Form N-600, N-600K, or simply a U.S. passport as proof of an already existing status.
Next, determine your legal basis and the date when you are eligible to apply. For standard naturalization, USCIS allows early filing — no earlier than 90 days before completing the required 5-year or 3-year period. If you apply too early, your application will be rejected.
The next stage is gathering documents. To file Form N-400, you typically need a green card, identification, valid and expired passports and travel documents, records of trips taken after obtaining permanent resident status, and, if applicable, marriage and divorce certificates, court documents, proof of compliance with child support obligations, and Selective Service information. Do not pay for the forms themselves: USCIS forms are free, and only the filing fee and related official services are charged.
You can submit the application online or by mail. As of 2026, online filing for N-400 remains a convenient option: USCIS notes that the system helps avoid errors, pay the fee, and track the case through an account. For children and consular cases, the process may go through the Department of State or separate USCIS forms rather than N-400.
After submission, USCIS schedules an interview where an officer reviews the application and the applicant’s background. If you do not qualify for an exemption, you will need to pass the citizenship test, which includes English language skills and knowledge of U.S. civics. For applications filed on or after October 20, 2025, the updated test applies: 20 questions are asked orally from a list of 128, and at least 12 must be answered correctly. For earlier N-400 applications, the previous 2008 test is used: up to 10 questions from a list of 100, with at least 6 correct answers required.
If your application is approved, you will be scheduled for a ceremony. It is important to note that a person becomes a U.S. citizen not at the moment of approval, but only after taking the Oath of Allegiance. After the oath, you can apply for a U.S. passport, register to vote, and, if applicable, file documents for children who automatically acquire citizenship through the parent.

Requirements for obtaining U.S. citizenship in 2026
The basic requirements for standard naturalization are:
- at least 18 years of age,
- lawful permanent resident status (green card),
- continuous residence in the United States for at least 5 years before applying,
- physical presence in the United States for at least 30 months out of those 5 years, as well as residence for at least 3 months in the state or USCIS district where the application is filed.
For spouses of U.S. citizens, a reduced timeline applies: 3 years in permanent resident status, at least 18 months of physical presence in the country, and 3 years of marriage to a U.S. citizen.
A separate requirement is good moral character. USCIS typically evaluates this over the 5 years preceding the application and up to the oath, though earlier conduct may also be considered. Issues may arise from false statements, certain criminal offenses, prolonged imprisonment, polygamy, human smuggling, repeated cases of driving under the influence, intentional failure to support dependents, and other unlawful acts. Therefore, professional assistance can be especially important in complex cases involving criminal history, long absences, prior denials, family disputes, or evidentiary issues.
Language and integration requirements are mandatory. In the standard process, applicants must pass tests in English and U.S. civics. However, there are exceptions: the 50/20 and 55/15 rules exempt applicants from the English test, while the 65/20 rule provides a simplified version of the civics test. In addition, Form N-648 allows applicants to request an exemption from the exam for medical reasons, including disabilities or cognitive impairments. Online citizenship tests are useful only for practice—the actual exam is conducted orally during the USCIS interview, not remotely.
Financial independence in U.S. naturalization differs from many European systems. USCIS does not focus on the size of an applicant’s capital but rather on permanent resident status, length of residence, good moral character, knowledge of English and civics, and the accuracy of the information provided. However, issues related to supporting dependents or failure to meet other obligations may negatively affect the outcome of the case.
U.S. Citizenship: Cost, Processing Time, and Waiting Period
When it comes to the minimum time before applying, under the 5-year pathway many applicants aim for 4 years and 9 months after receiving a green card due to the early filing rule. Under the 3-year pathway for spouses of U.S. citizens, the timeline is approximately 2 years and 9 months. However, this is only the earliest point at which you can submit an application—not the date you will receive U.S. citizenship. Any long trips abroad may significantly delay the timeline.
How long does it take to get a decision in 2026? USCIS clearly states that processing times depend on the specific office handling the case and the application category, and recommends checking current timelines using the official tool on its website. In practice, this means you should expect several months and refer to your specific office. USCIS has an internal target processing time for N-400 applications of around 5 months, but this is not a guarantee and not a universal benchmark—the actual timeframe depends on the individual case and the office reviewing it.
The filing fee for Form N-400 depends on the method of submission. According to USCIS, the reduced fee for low-income applicants is $380, which is half of the standard paper filing fee, while online filing includes a $50 discount. In practice, this results in a fee of $760 for paper applications and $710 for online submissions.
There is no separate fee for biometric data collection for Form N-400. If a household’s income falls within 150–400% of the federal poverty guidelines, applicants may request a reduced fee, and in cases of greater financial hardship, a full fee waiver may be available. For military applicants under special provisions, filing fees are generally waived.
In addition to the filing fee, you should consider extra expenses such as document translations, obtaining archival and court records, travel to the interview, and, if necessary, legal services. It is important not to rely solely on reviews: the cost of obtaining U.S. citizenship is rarely limited to the filing fee alone, but there is no need to overpay “for forms,” as all USCIS forms are free. If legal assistance is needed, it is important to work with a licensed attorney or an accredited representative.
Can You Have Dual Citizenship
Dual citizenship is generally permitted in the United States. USAGov explains that a U.S. citizen may acquire citizenship of another country without automatically losing U.S. citizenship. At the same time, the U.S. Department of State states that dual nationals must enter and leave the United States using a U.S. passport. It is also important to consider the laws of the second country: some allow dual citizenship, others restrict it, and some require renunciation of the original nationality.
Therefore, the question of “dual citizenship or second citizenship” always depends on both countries involved. For the United States, the main issue is usually not prohibition but additional obligations, such as taxation, potential military service, limitations on consular protection in the country of the second citizenship, and the requirement to use a local passport while in that country.
Formally, the Oath of Allegiance includes a renunciation of prior allegiance, but in practice, U.S. authorities generally do not require applicants to formally give up their previous citizenship. The main risks are more often related to the laws of the applicant’s original country rather than U.S. legislation.

Common Mistakes
When applying for U.S. citizenship, many applicants make common mistakes that can lead to denial or delays in processing:
- Filing an application without checking whether you are already a U.S. citizen through your parents.
- Underestimating trips abroad and their impact on residency requirements.
- Believing that marriage or giving birth in the United States automatically grants citizenship to an adult.
- Attempting to “buy” U.S. citizenship through intermediaries.
- Submitting documents too early.
- Providing incomplete or incorrect information regarding Selective Service registration.
- Issues with child support or undisclosed obligations.
- Failing to disclose past arrests.
- Paying for USCIS forms, which are actually free.
Therefore, before starting the process, it is recommended to assess your eligibility and, in complex cases, seek professional advice.
U.S. citizenship remains one of the strongest and most stable statuses for immigrants, but the path to obtaining it almost always depends on having a valid legal basis, careful document preparation, and an honest assessment of your background. For some, it is standard naturalization after 5 years; for others, it may be a reduced family-based pathway; for a child, citizenship through a parent; and for investors, athletes, or entrepreneurs, an immigration pathway first rather than immediate citizenship. If you want to understand how to obtain U.S. citizenship in your specific situation, the right first step is not to look for a “shortcut,” but to evaluate your eligibility, timelines, and potential risks, and only then begin the process.
Frequently Asked Questions about U.S. citizenship
We have compiled answers to the most common questions about obtaining U.S. citizenship. If you did not find the information you were looking for or want to learn more about the requirements, timelines, and benefits of American passport, contact us for a free consultation.
No. Online citizenship tests exist only as practice tools. The actual civics test is conducted orally during the USCIS interview, not remotely.
Yes. USCIS accepts Form N-400 online and states that online filing helps avoid certain errors, pay the fee, and track the case through a personal account.
USCIS usually provides a second attempt and schedules a re-examination within 60–90 days. If the applicant fails again or does not appear without a valid reason, the application may be denied.
Yes, but carefully. While your N-400 is pending, you remain a lawful permanent resident and must still preserve continuous residence and physical presence for naturalization. Long trips abroad can create problems for eligibility, and in some situations USCIS may treat extended absences as breaking continuous residence unless a specific exception applies.
Usually not. USCIS states that a Certificate of Citizenship (Form N-600) is an optional document, and a valid U.S. passport generally serves as proof of citizenship during its validity period.
If registration was required, USCIS will ask for your Selective Service number. If you are over 26 and did not register, USCIS may request a Status Information Letter. At the same time, USCIS guidance indicates that after age 31, no additional action is usually required on this issue.
U.S. citizenship is usually revoked not because of just any later crime, but because the person was not legally eligible to naturalize in the first place or obtained citizenship through fraud, concealment, or false testimony. In practice, denaturalization cases often involve concealed crimes, marriage fraud, immigration fraud, human smuggling, or criminal conduct that meant the applicant lacked the required good moral character at the time of naturalization.
The standard route is naturalization through Form N-400. In general, you must first confirm eligibility, prepare Form N-400 and supporting documents, file online or by mail, attend biometrics if required, go to the interview, pass the English and civics test unless exempt, and then take the Oath of Allegiance. For the common 5-year route, USCIS says applicants must be at least 18, have held permanent resident status for at least 5 years, show continuous residence, and be physically present in the U.S. for at least 30 months out of those 5 years.
