With either search keep in mind:

What do I do Next?
Remember this collection is an index. Be aware that its may contain inaccuracies, such as altered spellings and misinterpretations.

Use the information in this index to located your ancestor's actual naturalization records. You can then use those naturalization records to:


 * Learn an immigrant’s place of origin
 * Confirm their date of arrival
 * Learn foreign and “Americanized” names
 * Find records in his or her country of origin such as emigrations, port records, or ship’s manifests

Tips to Keep in Mind

 * Immigrants could naturalize in any court that performed naturalizations. That included city, county, state and federal courts. Begin by looking for naturalization records in the courts of the county or city where the immigrant lived.
 * Look first for the petition (second papers), because they are usually easier to find in courts near where the immigant eventually settled.
 * After 1906, the declaration can be filed with the petition as the immigrant was required to submit a copy when he submitted the petition.
 * Because immigrants were allowed to naturalize in any court, they often selected the most convenient court. If they worked somewhere other than their residence, they may have gone to a court closer to work to naturalize.
 * Look for the Declaration of Intent soon after the immigrant arrived, and then look for the Naturalization Petition five years later, when the residency requirement would have been met. Look for naturalization records in federal courts and then in state, county, or city courts.
 * An individual may have filed the first and final papers in different courts and sometimes in a different state if the person moved. Immigrants who were younger than 18 when they arrived did not need to file a Declaration of Intent as part of the process.
 * If your ancestor had a common name, be sure to look at all the entries for a name before you decide which is correct.
 * Continue to search the naturalization records to identify siblings, parents, and other relatives in the same or other generations who may have naturalized in the same area or nearby.
 * The witnesses named on naturalization records may have been older relatives of the person in the naturalization process. Search for their naturalizations.
 * You may want to obtain the naturalization records of every person who shares your ancestor’s surname if they lived in the same county or nearby. You may not know how or if they are related, but the information could lead you to more information about your own ancestors.

What if I Can't Find Who I'm Looking For?

 * Check for variant spellings of the names and for nicknames.
 * Try a different index if there is one for the years needed. You may also need to search the naturalization records year by year.
 * Search the indexes of nearby localities.
