Summary

Changes immigration laws to stop people who support socialist, communist, or Islamic fundamentalist groups from coming to or staying in the United States.

What does this bill do?

Blocks entry for ideological reasons
Makes any non-citizen who supports socialism, communism, Marxism, or Islamic fundamentalism ineligible to enter the United States.
Creates new grounds for deportation
Allows for the deportation of any non-citizen who supports or distributes materials for these specified ideologies at any time after their admission to the U.S.
Prevents citizenship for members of certain groups
Prohibits anyone who is or ever was a member of or affiliated with a socialist, communist, or Islamic fundamentalist party from becoming a U.S. citizen.
Eliminates judicial review
Makes decisions by immigration officials on these matters final and prevents them from being challenged or reviewed in any court.
Removes exceptions for membership
Gets rid of previous exceptions for involuntary membership in a banned party or membership that was required to get food or a job.
Eases citizenship revocation
Removes the five-year time limit for taking away U.S. citizenship from someone found to have been a member of a prohibited group.
Defines targeted ideologies and groups
Adds broad legal definitions for terms like 'socialism' and 'Islamic fundamentalism' and specifically names groups like the Democratic Socialists of America and the Muslim Brotherhood.

Who does this affect?

  • Immigrants
  • Asylum seekers
  • Naturalized U.S. citizens

What is the real world impact?

Restricts entry based on political beliefs
Could be used to bar or remove individuals based on their political or religious views, not just their actions. Critics may argue this limits freedom of speech and association for immigrants.
Uses broad definitions for targeted groups
Defines terms like 'socialism' so broadly that it could include many mainstream political groups, such as the Democratic Socialists of America, potentially affecting a wide range of people.
Removes court oversight
Prevents courts from reviewing decisions made under this law. This gives immigration officials final authority, which could lead to unfair rulings without a chance for appeal.

What problem does this solve?

Some members of Congress believe that certain ideologies are harmful to America. This bill names specific ideologies like communism and socialism as grounds to deny entry, deport, or revoke citizenship.

When does this start?

The changes would take effect as soon as the bill becomes law.
