For lawful permanent residents (LPRs), which is the status typically obtained by legal immigrants, the education requirement is to establish knowledge and understanding of U.S. history and government. LPRs must demonstrate this proficiency by passing a civics exam during the naturalization process. However, illegal immigrants are not considered LPRs and therefore do not have the same path to citizenship through education.
It's important to note that the specific laws and policies related to immigration and naturalization can change, and it's advisable to consult official sources or seek legal advice for up-to-date and accurate information.
