Texas Naturalization and Citizenship
Naturalization records for Texas have generally been filed with the clerk of the district court in each county. You can obtain copies of the declarations, affidavits, orders of admission, and other documents by contacting the clerk's office. The Family History Library has microfilm copies of some county records. For example, from Harris County the library has naturalization records from 1891 to 1906 and an index from 1855 to 1906.
In 1906 the Immigration and Naturalization Service (now United States Citizenship and Immigration Services) was created, forms were standardized, and duplicate records were created in the court and sent to the INS. To access these records, use the Genealogy Program at www.uscis.gov, fill it out and send it to the address listed on the form. You may also contact the National Archives—Fort Worth Branch for naturalization records.
