Good Evening! This afternoon I called the Niagara County Clerk's Office to find out where the records are if an ancestor did not naturalize but continued to operate on the Green Card. The response was to call INS. Following several attempts, I was informed that a FOIA form must be submitted. If you are having this trouble with finding your ancestor, from the 20th century, try <www.ins.gov>, then find Form #G639. Good hunting! Ellen Colangelo Wilson, NY
