"It is the policy of the United States to protect its citizens from foreign nationals who intend to commit terrorist attacks, threaten our national security and public safety, incite hate crimes, or otherwise exploit the immigration laws for malevolent purposes," President Trump said. "The United States must exercise extreme vigilance during the visa-issuance and immigration processes to identify, prior to their admission or entry into the United States, foreign nationals who intend to harm Americans or our national interests." The president continued, "The United States Government must ensure that admitted aliens do not intend to threaten its citizens; undermine or destabilize its culture, government, institutions, or founding principles; or advocate for, aid, or support designated foreign terrorists or other threats to our national security." |
