To become a citizen, the alien immigrant had to first apply at a court for a  Declaration of Intention (first papers).   Later he would apply for the Petition for Naturalization (second or final papers).  Then, the Naturalization Certificates themselves, were issued to the naturalized citizens upon completion of all citizenship requirements.   This process took several years to complete as discussed below.   The records that are filed in the courts (and those that you may search for) are the Declaration of Intentions and the Petition for Naturalization.  The Naturalization Certificate was given to the naturalized citizen and you may only find it in your ancestor's personal effects.

8.1 Naturalization  - Before 1906

8.1.1 Naturalization Requirements and Records - Before 1906
Following the Revolutionary War (1776), all white residents of European descent that were born in the colonies or loyal to the Revolutionary cause became citizens.  It was not until 1790 that the first statute regulating naturalization of aliens was enacted.  But, the first definitive statute that became the basis for naturalization for the next century was enacted by Congress on 29 January 1795.  These naturalization provisions included:

• Alien must be a free white male or single female - 21 years or older 
  
• Alien must have been  resident in the United States for 5 years to file for the Petition for Naturalization
• Alien must have been resident in the state where naturalized for 1 year (Changed to 6 months in 1940)
• Alien must first have filed his Declaration of Intentions at least three years (changed to 2 years in 1824) before filing for the Petition for Naturalization.
• Wives and minor children automatically became citizens when the husband/father was naturalized.  The names of wives and minor children were not always listed on the Declaration of Intentin or Petition for Naturalization.
  

• From 1824 a child, who was under 18 years when he arrived, could be naturalized without filing a Declaration of Intention (One paper naturalization) when he reached age 21, was a resident of the U.S. for 5 years, and was resident of the state for 1 year.
• Alien Wives became citizens upon marriage to a US citizen husband, or upon their husband’s naturalization since February 10, 1855 until 1922 (when a women’s citizenship was separated from their husband’s.)
• Women who were citizens and married an alien lost their citizenship.
  
• After 1862, honorably discharged veterans of the U.S. Army who served during wartime, and was resident in the US for at least one year, could be naturalized without filing Declaration of Intention (Extended to Navy and Marine Corps in 1894).  The Act of May 9, 1918 provided for the immediate naturalization of an alien in Service during WWI.  They were naturalized in military camps or nearby courts without declaration of intention, certificates of arrival, nor proof of residency.
• In 1868, the 14th Amendment to the Constitution provided for blacks to automatically become citizens.

Note that an alien did not have to file the Petition for Naturalization in the same court that he filed his Declaration of Intentions. (For example, my grandfather filed his Declaration of Intentions in the Hamilton County, Ohio court.  His Naturalization Petition was filed in the Court of Common Pleas in the City of New York).

Generally, most pre-1906 Petitions for Naturalization papers contain little information of biographical or genealogical value.  In the majority of these early papers, only the name of the individual, his or her native country, and the date of the naturalization are given.  However, the Declaration of Intentions in a number of these pre-1906 papers may contain useful information including;

• The country of origin,
• The port of arrival,
• The port of embarkation, and
• The date of arrival in the United States.

8.1.2 Locating Naturalization Records - Before 1906

Naturalization records were kept at the court which issued those records.  You may find Declarations of Intention and Petitions for Naturalization that were filed in state or local courts in the County Clerk's office closest to the immigrant's place of residence.  However, these records may now be located at the county or state archives.   Some, such as for the New England States are at the National Archives.

Naturalization records that were filed in United States District or Circuit Courts are in the custody of the Courts or the National Archives, and are stored at one of the Regional Archives or Federal Records Centers.  For example, the National Archives Regional Office in New York has naturalization records filed in local, state and federal courts located in New York City (1792-1906) and in District Courts including those in New Jersey.

Naturalization Records by Repository - New York and New Jersey
Table 1 lists the present location of the naturalization records for most of the courts for New York and New Jersey.  You can contact these courts to locate the naturalization records.

These records have been indexed by the WPA.  Note that the information on the Index Cards are arranged using the Soundex system and includes the following:
    Name of the Individual
    Name and Location of the Court,
    Volume (or Bundle) and the Page (or Record) (This information is needed to locate the copy of the actual record)

1. )   You may want to start your search for the Declaration of Intentions in the area where the alien lived shortly after arriving in the U.S.  If you fail to find that,  you should search for the Petition for Naturalization in the cities or counties where he subsequently lived.   (Sometimes, the Declaration of Intentions will be "attached" to the Petition on the microfilm records).   To search for these records, you should know your ancestor's year of naturalization, so you may therefore know where he lived and thus the locality of the court where he filed his papers.  The year of naturalization may be found in the 1920 census records as discussed in Section 2.0 of this Guide.

2.) The LDS Family History Library has microfilms of many of the indexes to the naturalization records and naturalization records themselves.  Unless you are near the court where the records may be stored, it may be the best place to start your research.  To locate these records in the LDS catalog,   use the Place search and look under  [County][State] - Naturalization and Citizenship
Note:  There are separate indexes to the declaration of intentions and to the naturalization petitions.  You may want to initially search for the declaration of intentions.  If you fail to find that document, search for the naturalization petition.   You may find a copy of the declaration of intentions attached to the Naturalization petition if the declaration of intentions had been filed in a different court.

3.) You may call or send a letter to the local county courthouse, State Archives, or NARA.  Provide as much known information as possible to help in locating the documents.

Beware!  Some clerks at the local courthouses either do not know about the existence of the naturalization records in their buildings, or are uncooperative.  They may indicate that the records were moved, etc.  Persevere in your search!

8.2 Naturalization  - After 1906

Then, in 1922, women could not become a citizen by virtue of her marriage to a citizen, but had to apply for citizenship.

The Declarations of Intention produced after 1906 may have the following information:

• Alien's Name, Marital Status, Address, and Occupation
• Alien's Birthplace, Nationality, Country from which emigrated, and Last Foreign Residence
• Alien's Birth Date or Age and a Personal Description (sex, complexion, eye color, hair color, height, weight, visible distinctive marks)
• Port and Date of Entry and Name of Ship

• Length of time in the United States and the date of the Declaration of Intention
• Photograph (after 1929)

• Name of Spouse, Marriage Date, Marriage Place, Birthplace of Spouse, Birth Date of Spouse, Date and Place of Spouse's entrance to the United States, and the Current Residence of Spouse
• If the spouse is a naturalized citizen,  Where and When the Naturalization took place
• Number of Children born to him or her, and the Date and Place of Birth of each.  If not born in the U.S., where and when their lawful admission for permanent residence in the United States took place.

The Certificate of Naturalization were issued to naturalized citizens upon completion of all citizenship requirements   Most Certificates of Naturalization contain only the name of the individual, the name of the court, and the date of issue. However, the amount of information on these certificates varied from year to year and much additional information may be found on them.

The 1906 law required that all applicants for naturalization be legally admitted to the US and applied to all immigrants arriving after June 29, 1906.  Documentation was required to be submitted by the immigrant at the time he/she filed a Petition, showing the name under which they arrived, the date of arrival, port of entry and the name of the vessel.  This information was verified and a Certificate of Arrival for Naturalization Purpose was issued by the Department of Labor, Immigration Service and is attached to Petitions filed after 1911.  

8.2.2 Locating Naturalization Records - After 1906
