The Process To obtain U. S. Citizenship In 2025
Immigrants can obtain American citizenship through various means, but the process itself is not simple. This is because it is usual to have first become a lawful permanent resident.
There are several immigration processes through which you can carry out the adjustment of status or the consular process to obtain the Green Card. For example, through family petitions or employment sponsorship.
In any case, the basic steps of the process to obtain citizenship include:
1# Determine If You Are Already An American Citizen

You can obtain U. S. citizenship by birth or through naturalization In two ways:
- By birth, or
- Through naturalization.
Generally speaking, individuals are U. S. citizens from birth if they are born in the U. S. or abroad as children of U. S. citizens:
You can also acquire citizenship in the following cases:
- You are under 18 years of age and a lawful permanent resident and one or both parents are naturalized.
- After being adopted by an American citizen parent.
2# Determine Your Eligibility To Obtain American Citizenship
Generally, you can qualify for the naturalization process and obtain American citizenship if you:
- Are 18 years old,
- Have been a lawful permanent resident for a certain period of time, and
- Meet all eligibility requirements for the process.
Likewise, you may qualify for naturalization based on military service. However, this has specific requirements for it.
The U. S. government recognizes the sacrifice the military makes for the country. For this reason, it offers exclusive programs for them, such as Military Parole in Place. Such a program allows family members of military personnel to obtain a Green Card if they meet certain requirements.
3# Prepare Form N-400, Application For Naturalization
Once you meet all the requirements to obtain American citizenship, you must complete Form N-400 to begin the process.
You can create an account and file your N-400 online, giving you the ability to:
- Receive alerts about the status of your case,
- Send messages,
- Review all correspondence related to the case,
- Check your current status,
- Update personal information, and
- Send evidence when necessary.

You should be careful not to make mistakes when completing the N-400 naturalization application, as this would affect your application. Additionally, USCIS may request additional information if your filing is incomplete. This usually delays the process.
4# Submit Form N-400 To USCIS
Submit your application, along with the required documents and applicable fees, to USCIS.
If you reside outside of the United States, please include passport-style photographs with your application.
After submitting Form N-400, you can check current processing times and application status through your USCIS account.
5# Go To The Biometric Services Appointment
USCIS requires applicants to provide fingerprints and have photographs taken. This is to conduct criminal background checks through the FBI.
It is important that applicants have completed a background check before USCIS schedules an interview.
6# Complete The USCIS Interview
After completing the preliminary processes, USCIS will schedule an interview with you.
Appear on the date and time indicated on your appointment notice and carry this notice with you. Attendance as well as punctuality are key. If you are unable to attend, follow the instructions on the notice to contact the office to reschedule your appointment.
Keep in mind that this can add several months to the process of obtaining American citizenship.

7# Receive USCIS Decision On Form N-400
You will receive a written notification regarding the USCIS decision, which may be:
- Granted: If the recorded evidence confirms your eligibility for naturalization.
- Denied: If the evidence recorded establishes that you do not meet the requirements for naturalization.
- Continued: If you have to provide additional evidence, you did not submit the appropriate documents or you have failed an exam.
If your request is approved, continue with the next step. Otherwise, you may be able to appeal the decision in your immigration case.
8# Wait To Receive A Notice To take the oath of allegiance
With the application already approved, USCIS will send you a notification by mail to take the oath of allegiance. In this you will see the date, time and place of the oath.
In some limited circumstances, you may have the option to participate in an induction ceremony on the same day as the interview. If you are unable to attend the ceremony and wish to reschedule, follow the instructions on Form N-445.
9# Take The Oath of allegiance To The United States
You will not be a U. S. citizen until you take the oath of allegiance to the country at the naturalization ceremony. This is handled by USCIS in an administrative ceremony or by a judge in a judicial ceremony.
Once you complete it, you will receive your naturalization certificate and hand over your Green Card, as you will no longer need it.

Other Ways by which you can become an American Citizen

Once done, you will be able to obtain citizenship after 5 years after obtaining the Green Card. But he must have lived in the U. S. for 30 months.

- Are not obliged to make a definitive decision between one nationality and another.

If you are in the U. S, contact the other country’s embassy or consulate to confirm recognition of dual nationality.
Can I Become A U. S. Citizen From Abroad?
Although certain individuals can become American citizens if they were born outside the United States, it is not possible to naturalize if they are outside the country.
Therefore, you must remain physically in the U. S. to become a citizen through naturalization.
How Can I Become A U. S. Citizen Without Knowing How To Speak English?
Although speaking English is mandatory to complete the process to obtain American citizenship, there are exceptions.
For example, those over 50 who have lived in the United States for a certain period of time.
Can I Lose My American Citizenship?
American citizens by birth cannot lose their citizenship against their will. This is according to the 14th amendment of the Constitution. Although, they can choose to renounce.
On the other hand, foreigners who managed to become American citizens through naturalization can lose it. This process is called “denaturalization” and they could be subject to deportation from the country.
Denaturalization can occur for a variety of reasons, including:
