The federal statute of limitations for illegal entry, also known as illegal entry into the United States, is generally two years from the date of the commission of the crime. This means that the government has two years from the date of the crime to bring criminal charges against an individual for illegal entry.
It's important to note that this is a general rule and that some other specific circumstances may affect the statute of limitations for illegal entry offenses. For example, if the defendant has fled the jurisdiction, the statute of limitations may be tolled (or extended) until the defendant's return.
Additionally, if an individual is found to have entered the country illegally and then commits another crime, the statute of limitations for the illegal entry may be extended to cover the time period of the additional crime.
It's always best to consult with an attorney to determine the specific statute of limitations for a particular case.
