The Alien Registration Act

The overview including its background is listed throughout the clarification segment described.

Explanation:

The Alien Registration Act would be signed into law on June 29, 1940, making it more difficult for anybody outside the U.S to promote, encourage as well as demonstrate the relative attractiveness of destabilizing the country. The legislation, therefore, mandated all alien immigrants throughout the U.S over fourteen years of age to provide a detailed declaration of everyone's work-life classification as well as a document of certain ideological opinions.
