Question

Does the United States Bill of Rights apply to immigrants?

Answer 1

It applies to all legal immigrants who have completed the citizenship requirements.

Explanation:

All U.S. laws apply to all U.S. citizens and aliens in the country. Specific "rights" may be claimed by citizens as well, but are not granted to any person who is not yet a full "citizen" of the United States.
The short test is this: If someone can obtain a U.S. Passport, they may claim the Bill of Rights.
