Restoring Northern Border Travel Act This bill requires the Department of Homeland Security (DHS) to expand the list of permitted essential travel into the United States through land ports of entry along the U.S.-Canada border. Specifically, it shall be permitted essential travel to enter the United States through the U.S.-Canada land border to (1) visit a family member who is a U.S. citizen or permanent resident, (2) visit property that the traveler owns or leases, (3) attend business meetings or site visits, or (4) board a flight for travel. Within 20 days of this bill's enactment, DHS must report to Congress a plan to fully restore nonessential travel into the United States through this land border.
