Alien and Sedition Acts
It was made of four acts.
The first three acts were about immigration. They made it required time for an immigrant to become a citizen and also allowed the president to send illegal immigrants back to their home country if their home country is at war with the United States or they are considered to be dangerous to the peace and safety of the United States. The fourth act made it illegal to publish bad things about the government.
The acts were very controversial (many people did not like them because they felt that they violated the First Amendment).
