Trump approves updated travel restrictions on 8 countries, adding North Korea and Venezuela to list

The new travel restrictions, set to take effect Oct. 18, would slow or limit entry from citizens of North Korea, Chad, Iran, Libya, Somalia, Syria, Venezuela and Yemen. North Korea and Venezuela were not listed in the earlier ban.

Iraqi citizens do not face the same travel restrictions, but will "be subject to additional scrutiny to determine if they pose risks" to U.S. security, the White House said.

The new policy could complicate the Supreme Court's review of the order. The high court is scheduled to hear arguments over its legality on October 10.

Officials stressed that valid visas would not be revoked as a result of the proclamation. The order also permits, but doesn't guarantee, case-by-case waivers.
