It is generally not possible for an individual to find this information as it is private, the information could be used to harass, target, or discriminate against people. Law enforcement and immigration have access to those records if they exist (thereu2019s no record for status achieved at birth, but thatu2019s not generally tracked at the federal level).Reporting is not against the law, so statutes of limitations donu2019t apply. I think you are probably asking if thereu2019s a statute of limitations on immigration fraud. Thatu2019s a good question. Federal laws generally have a statute of limitations of 5 years. Traditionally, US immigration has considered itself exempt from such limitations since most immigration activities are considered administrative and not criminal (for example, itu2019s not illegal to enter the US and over stay, but it is a procedural violation that can result in deportation). However, immigration fraud for naturalization is a criminal offense and should technically be subject to the statute of limitations u2023 but I doubt US immigration would see it that way and presume that thereu2019d be a protracted legal battle. Further, it might be pointless since if the person lost their original citizenship by naturalizing in the US, thereu2019s a good chance that they cannot be deported anyway and all it would do is prevent them from ever leaving the US.If you knowing file a false report, thatu2019s a crime. If you file a report in good faith, and it turns out thereu2019s no fraud, thereu2019s a good chance youu2019ll get sued by the person who you had reported.
