Citizenship and Naturalization
Publication Date
These three charts, updated on July 19, 2022, outline the different requirements for acquiring and deriving citizenship. Because the law governing acquisition and derivation has changed many times and is generally not retroactive, these charts detail what the eligibility requirements are depending on the time period in question. Each chart has extensive footnotes that provide explanations about the legal requirements, possible arguments where there is any ambiguity, and cites to further resources.
