Father past away 5 years ago, which was a citizen. Mother has never step foot in the United States. Step-mother, who held all my records, also past away eight months after my father. I am a citizen born abroad, and I would like to know a list of files that i must have to be safe. All i have is my drivers license, social security card, and a copy of my born abroad certificate(not original)
Look at the instructions for filing Form N-600 Certificate of Citizenship. It contains a detailed list.
