There were 4 acts passed in 1798 that are collectively referred to as the Alien and Sedition Acts:
The Alien Friends Act sanctioned confinement and deportation of non-denizens who were deemed hazardous.
The Alien Enemy Act sanctioned the same for those from a truculent country.
The Sedition Act criminalized making erroneous verbal expressions that were critical of the regime.
The Naturalization Act made it harder for an immigrant to become a denizen.
