Application for Naturalization (Form N-400)

Hello my friends! I finally filed my Form N-400 (Application for Naturalization) to become a U.S. Citizen. Last (but not the least) document to be filed at USCIS. By this time – you probably master filing documents already by your own. 🙂

However, I still want to document my process and share it with you. This time I filed my application online and it went so easy and less stressful.

Date Filed: Jan. 29, 2019
Biometrics: Feb. 19, 2019

First Let’s check the Eligibility:

As always – check the eligibility at the USCIS website under Citizenship and Naturalization and then I listed down below based on my applicable eligibility which is the spouse of the US Citizen.

☑ Must be 18 yrs old or older
☑ Must have an LPR or Lawful Permanent Resident Card.
~ In my case – me and my son have a 10 yr green card.
☑ Must have continuous residence in the US as an LPR for atleast 5 years or 3 yrs. if you are married to a US Citizen.
☑ Show that you have been physically present in United States for 30 months, 18 months if you are married to a US citizen.
☑ If you traveled outside US within this time period, travel should be no more than 6 months. You will encounter this when you fill-up up the form N-400).
☑ Show that you have lived for at least 3 months in the state or USCIS district where you claim your residence.
 ** Scanned copy of passport is enough to show that you did not leave the US for the past 3 months or 3 years for more than 6 months.
☑ Must have an attachment to the US Constitution and be well disposed to the good order and happiness of the United States during all relevant periods under the law.
☑ Must be able to read, write, and speak and understand English and have knowledge and an understanding of U.S. history and government – This is now our homework.

After checking my eligibility – I realized that:
→ I am more than 3 years after receiving my 2 yr card and
→ 6 months 10 yrs green card holder upon checking my eligibility (January 2019)

So good to go!

How to File Form N-400?

You can file Form N-400 either through mail or through on-line.
I chose to file on-line because the Form N-400 itself consists of 20 pages, plus adding supporting documents – it’s a little handful. So I gave on line filing a try.

Form N-400 On line filing

I find it – simple, easy, fast and straight forward. Every category are divided into different tabs: Getting Started, About You, Your family, etc. and you just have to click or type the answer that applies to you. See below screenshot.

For the required documents, you just need to have a printer/scanner and have your documents scanned – jpeg, word document or excel format or pdf format are acceptable. I just converted mine to PDF format for uniformity. Then upload it on the “Evidence” Tab. Easy!

If you forget to upload a specific document, you can always go back and check the documents you uploaded so far and upload more documents needed. You have 30 days to finish the on line application while gathering all your requirements.


After referring to USCIS Website Form N-400 Required Documents ~ Here are the actual requirements I submitted on-line, all are scanned and converted to PDF file.
