Are there an on-line indices for naturalizations in Passaic for the 1920s? Would the records be stored locally or do I have to go to the INS for a search? If local, where and how do I request copies?

My g-grandfather Morris SCHNEIDER arrived in Passaic County, New Jersey (Patterson) from Poland in 1922, stayed for a while, went back to Poland, and returned with the entire family in 1928. Per the 1930 census, the family is living in Patterson and Morris is listed as being a naturalized citizen and so are all of the children.

Thanks for any help. Most of my experience is with Brooklyn & Manhattan.
