The purpose of this legislative proposal is to modify U.S. immigration law to make it illegal for individuals to advocate for Sharia law if such advocacy would infringe on the rights of others as defined by the U.S. Constitution or federal and state laws. The bill is titled the "Preserving a Sharia-Free America Act" and aims to enhance national security by preventing individuals who promote Sharia law from entering or remaining in the United States. Key provisions of the proposal include several important requirements.
