US Naturalization Documents Overview

Let’s take a quick look at the 4 types of US Naturalization documents you need to know about for your jure sanguinis application for gaining Romanian citizenship.

  1. Declaration of Intention

The Declaration of Intention to naturalize would have been Step One of the citizenship process for your ancestor.  The document looks something like this:

Basically, this is a piece of paper that formally registered your ancestors intention to become a naturalised US citizen. After filing the declaration, your ancestor would have to wait some requisite amount of time – normally between 1 and 3 years – before going to step 2 of the naturalisation process.


2. Petition for Naturalization 

Once your ancestor filed the Declaration of intention and waited the requisite amount of time, he or she could formally file for a petition for naturalisation, sometimes called a petition for citizenship.

This document looks like this:

3. Oath of Allegiance

This is the pledge your ancestor would have had to take to swear allegiance to the United States before he/she would be issued a Certificate of Naturalization.  The oath looks something like this:

If you already have your ancestor’s Oath in possession, congratulations!  For our purposes, the most important part of the oath is found at the bottom… If you have your ancestor’s Oath of allegiance, look for the Certificate Number – or C-File number – at the bottom right hand corner of the document.  This will help you later on if you need to request the Certificate of Naturalization. 


4. Certificate of Naturalization

Finally, we come to the Certificate of Naturalization.  The Certificate of Naturalisation is the document issued after a US citizen hopeful completes all of the citizenship requirements and has signed the oath of allegiance to the United States.  In other words, this certificate shows that the naturalisation is DONE DEAL.

The Certificate of Naturalization looks something like this:

This document is required in the procedure for gaining Romanian citizenship through your ancestor, and is only available via United States Citizenship and Immigration Services USCIS website. However, USCIS only holds Certificate of Naturalisation (c-file) records for naturalisations that occurred between  September 27, 1906 – March 31, 1956.  In other words, NARA and the local Courthouse can’t provide this document.
