Filing and Writing Tips for N-400 Cover Letter

The N-400 naturalization application is a very important matter for any immigrant applicant. Many immigrant applicants have waited for at least five years since they moved to America and have enough proof or substantial evidence that they have lived in the country continuously before they can start to apply. This is the reason why it's absolutely necessary that the N-400 naturalization application cover letter needs to be written professionally. Try to write it briefly but don’t forget to introduce the important facts or conditions that are relevant to your application for a few sentences only so that you will not waste the immigration officer’s time.

These important writing tips can benefit you when you start drafting your N-400 naturalization application cover letter:

Place a top cover of your folder packet with the type of submission that you will send to the USCIS. An example will be Application for Naturalization with the Applicant’s Name and A-Number (alien number) with it.

Clearly mark your important documents involved with the type of submission. Remember to add a date for your cover letter. Address the USCIS in a respectful manner. Offer a short introduction or explanation of the reason why you are writing to the USCIS. Remain professional throughout your cover letter and include your fee too.

Remember to add the itemized list of documents that you shall send alongside the N-400 Application for Naturalization cover letter. You need to request that your Application for Naturalization be looked at in a timely manner. Don’t forget to thank the USCIS immigration officer for the time that will be given for your case. Remember to sign your Application for Naturalization cover letter. Double check and sign your official documents that needed to be signed. Avoid adding to the list a document that you will not be sending.

Make sure that you use your full, legal name based on your permanent resident card, driver’s license or passport at all times.

If you shall request a waiver of the 100 Civics Test or English language due to your age, the Application for Naturalization cover letter is the ideal paperwork to start and you can clearly explain it through this document. In case for applicants with a disability that requires special accommodations, the cover letter will provide additional information to USCIS about your present condition. The Application for Naturalization cover letter shall provide important information on why you need special attention with your case, so that the immigration officer who will be assigned to your case will be prepared in advance.

The advantage of adding a cover letter to your Application for Naturalization is that, it will let you recheck easily the documents that you will be submitting to the USCIS and this will make you sure that everything is included before you send your entire packet to them. We highly recommend that you also allow your loved ones or a trusted friend to recheck the entire packet if everything is included or spelling checked before sending it to the USCIS.

Please take note that application packets can easily be processed as quickly as possible when you will be able to submit it correctly to the USCIS office who will handle your paperwork. 

Once you will start submitting the Form N-400, Application for Naturalization, try to assemble it via a packet and only the required paperwork or documents that will apply to your application shall be placed inside. Try to have two (2) packets so that you will have your own exact copy once you will submit the other one to the USCIS. Read the Manual M-476, A Guide to Naturalization, which contains the “Document Checklist” listing two pages of documentation that immigrant applicants need to include for their application package. 

A good cover letter will offer an opportunity for any immigrant applicant to assemble important identifying information that shall confirm that he or she has fulfilled the requirements making him or her eligible for naturalization, by picking out and emphasizing any concerns or circumstances associated with the application case, and detailing the documents included in the package or packet. 

Please take note that the information that you will include in your naturalization application cover letter should be short and clear, avoid adding unnecessary words in connection with the information provided within your application packet.


Immigrant applicants should list the date on which they were granted permanent resident status in the first paragraph of the cover letter. The following sentences needs to indicate that the immigrant applicant has fulfilled the number of years for his or her residency and other important requirements in order to qualify for naturalization.

Point out any important concerns or unusual circumstances associated with your naturalization application in the second paragraph. This should be brief, as paperwork within the packet should contain any needed details.

The third paragraph for your cover letter application is useful for listing the documents included in the entire packet. The fourth paragraph is usually about the request that you would like the USCIS to process the naturalization packet the soonest possible time. This is the part of the cover letter where immigrant applicants shall politely request that the USCIS office contact them with any concerns or questions and provide the email address including the phone number. The last part or the closing sentence should thank the USCIS officer for the time and attention offered to your application case.

Please remember that you may also pay using a credit card. There is no additional fee when you do so. The N-400 is the only form that you can pay by credit card using the G-1450, Authorization for Credit Card Transaction.
