At last (!) ....From 13th August the USCIS Genealogy Program will go "live".
This is a new online fee-for service program for genealogy requests for US immigration and naturalisation records and replaces the previous service whereby requests had to be made in writing under the Freedom of Information Act and could take anything up to 18 months. The USCIS hold the records for all of the US.
The records available include Naturalisation Certifcate files from 1906-1956. As well as the Naturalisation certificate these files (C-files) contain Declaraton of Intention and Petition for Naturalisation therefore may contain much genealogcal info such as date and place of birth, occupation, arrival details as well as addresses and famly names.
The requests are to made in two stages. Firstly an index search, which will cost $20 (subject must be born over 100 yrs ago or else submitter must provide proof of death). Then when info is found a request can be made for copies of the immigration and naturalisaton records. The published fees are: Copy of Document from Microfilm: $20 and Copy of Textual File: $35.
