Older Records in Archive at the County
The Sussex County Clerk’s Office does not record and/or file current naturalization or immigration records. We do, however, have a record of older petitions for naturalizations available in our Records Room, dating from 1808 through 1987. If you are unable to visit our records room in person, you may provide a written request for the information you seek.
Requirements for a search of Petitions of Intent for Naturalizations
- Name of person in question (all possible names and spellings)
- Date of birth of people
- Approximate date of naturalization, petition number if you have it
- Address at time of naturalization
We do not carry naturalization certificates. All certificates are in Newark. If making a request by mail, be sure to include your name and return address where you want your documents mailed.
What it will cost
Copy of record is $2.00/page (average of 3 pages)
Certification of record (if required) is $10.00 for certification (plus $2.00/page)
NOTE: If you are mailing your request, it is recommended that you include a blank check made out to the Sussex County Clerk with a referenced “Not to exceed $xx” amount. The Clerk’s Office staff will then fill in the appropriate amount owed and provide a receipt together with your mailed document. Mail your request and payment to: Sussex County Clerk, 83 Spring St., Suite 304, Newton, NJ 07860.
