Other eligibility requirements

There are certain conditions which apply across all categories such as:

  • being 18 years of age or older (most categories)
  • being of good moral character
  • having an English and civics knowledge
  • being willing to form an attachment with the US constitution

In addition to the above, the following are general requirements on naturalization applicants:

Time as Permanent Resident, Continuous Residence and Physical Presence

In most of the eligibility categories above, a period of time already spent as a Permanent Resident in the USA will also be required before an individual can apply to naturalize.
Where continuous residence is required, it is obtained by not leaving the USA for long periods of time, usually no longer than 6 months. There are some exceptions to this, such as time abroad spent in the employ of the US armed forces.

Physical presence concerns the actual number of days you are present in the USA, and therefore does not include any time spent out of the country. You may have arrived in the USA 3 years ago, but if you spent 4 weeks of that time abroad, then your physical presence is 3 years less the 4 weeks.

Time as a Resident in a USCIS District or State

Generally, you must reside in the USCIS district or state where you are making your application for naturalization for a minimum of 3 months.

Good Moral Character

Having a good moral character takes into account whether you have been truthful in your application and interview, have a criminal record, or have taken part in some other activity or behaviour which would suggest that you do not have a good moral character.

English and Civics

You must have the ability to read, write and speak English, and an understanding and knowledge of American history, laws and government.
You can obtain guidance materials from USCIS to help with English and civics tests, including finding where you can attend English classes.

Attachment to the Constitution

Anyone applying for naturalization must be willing to defend and support the USA and its constitution. You declare this intent by taking the Oath of Allegiance to renounce foreign allegiances, support the constitution and serve the USA.

How to apply for US Naturalization

Applications for US naturalization are made using form N-400.
Complete the N400 form as fully and truthfully as possible, gathering any supporting documents (such as photocopies of your Permanent Resident Card). Retain a copy of the form, once completed, for your own records.

Wherever you send a copy document with your N-400 form, you should ensure that you bring the original document to your interview, if requested.

Send your N400 form, supporting documents, and application fee to the USCIS Lockbox that serves your area.

Biometrics

Once you have filed your application with USCIS, you will receive a letter stating where and when you may have your biometrics taken.

When you attend your biometrics appointment you should take:

  • ASC appointment notice (form I-797C)
  • Permanent Resident Card
  • a form of identification which displays your photo, such as a driver’s licence or passport

You may be asked to bring additional documents, such as a marriage certificate, depending on your personal circumstances.

At the interview, your fingerprints will be taken, you will be photographed, and asked to provide your signature. Your fingerprints will be forwarded to the FBI (Federal Bureau of Investigation) in order to carry out a criminal background check.

Additional Information

At this point, USCIS may request additional documents from you before they can arrange your interview. If this is the case, you will receive a letter outlining the information required.

Interview

Once everything is in place, an interview will be arranged for you. USCIS will send you a letter informing you of your interview date, time and venue.

On the day of your interview, you should arrive 30 minutes before the scheduled time, and bring the following:

  • Permanent Resident Card or Alien Registration Card
  • passport
  • State Identification Card
  • Re-entry Permits, if you have any

You may be asked to bring additional documents depending on your personal circumstances. These will be mentioned in your appointment letter.

You will be interviewed by an USCIS officer who will question you on your background, evidence submitted in support of your application, your place and length of residence, and your character among other areas, required to satisfy the USCIS officer that you are eligible for US naturalization.

You may take a representative with you to your interview, but you must have sent a Notice of Entry of Appearance as Attorney or Representative form (G-28) with your application form. If you are exempt from the English requirements, you may take an interpreter with you. If you have any disabilities, you may be accompanied by a relative or legal guardian at the discretion of the USCIS officer.

Your English skills will be tested during your interview unless you are exempt from the English requirements, and you will also be asked to take a civics test.
Once your interview is over, you will be given an N-652 form, stating the results of your interview. Your application for naturalization will either be granted, put on hold, or denied.

Should your application be granted, you will either be asked to attend an oath ceremony on the day of your interview or sent a notice informing you of when and where your oath ceremony will take place.

Should your application be put on hold (continued), you will be asked to attend a second interview or to provide additional documents.

Should your application be denied, you will receive a letter stating the reasons.

Taking the Oath

Unless you are asked to attend an oath ceremony on the day of your interview, you will receive a Notice of Naturalization Oath Ceremony (form N-445), stating when and where you should attend an oath ceremony.

On the day of the ceremony, you should dress smartly, arrive 30 minutes early, and check in with USCIS. You will be asked to return your Permanent Resident Card when you check in. You may be questioned further before the ceremony takes place. These questions will be listed on the back of the N-445 form that you received.

At the oath ceremony, you will be asked to recite the Oath of Allegiance so that you may become a US citizen.

After you have taken the oath, you will be given your Certificate of Naturalization which is proof of your status as a US citizen.
