Why isn't public law 414, which bans anyone from entering the country who wants to overthrow the US, being enforced? Public law 414 of 1952: (Dec. 8, 2015) — The Immigration and Nationality Act passed June 27, 1952 revised the laws relating to immigration, naturalization, and nationality for the United States. That act, which became Public Law 414, established both the law and the intent of Congress regarding the immigration of Aliens to the US and remains in effect today. Among the many issues it covers, one in particular, found in Chapter 2 Section 212, is the prohibition of entry to the US if the Alien belongs to an organization seeking to overthrow the government of the United States by “force, violence, or other unconstitutional means.” This, by its very definition, rules out Islamic immigration to the United States, but this law is being ignored by the White House.
