The Supreme Court has allowed the third version of the Trump administration’s ban to go into effect while legal challenges against it continue. The court’s orders mean that the administration can fully enforce its new restrictions on travel from eight nations. For now, most citizens of Iran, Libya, Syria, Yemen, Somalia, Chad and North Korea will be barred from entering the US, along with some groups from Venezuela. Restrictions vary depending on country and circumstances. In reaction, Greeley Koch, executive director of the Association of Corporate Travel Executives said that as governments seek to implement new border and immigration protections along with new security policies they must keep in mind two criteria: one, that the policies be clear, understandable and easy to follow; and two, that the policies take into account “the substantial economic benefits of business travel, both on a domestic and international level, and balance the need for safety with the need for cross-border commerce.” Koch said ACTE will continue to monitor how the ban is implemented and will gauge the impact to business travelers.
