According tot he fourth amendment, in order to legally search a person's property a government must: A) have a search warrant
The fourth amendment of united states prohibit the government to conduct unreasonable searches and seizures. The only reason that can be use to justify search without a warrant is if it involves emergency situations (such as if the police heard a scream or gunshots).
The answer is true. There
was several times where the United States restricted the entry of certain
groups of people into their country. These
was regulate who would enter their country.
Today that is no longer being practiced as restrictions are now being
removed.
