Organizers and police expect several thousand union members and immigration policy activists to take part in a May Day march on the Las Vegas Strip.
Culinary Union spokeswoman Bethany Khan says the Monday evening demonstration is expected to gather hotel workers ending their work day at Las Vegas Boulevard resorts for a walk across an Interstate 15 overpass to a rally at a vacant lot near the Palms hotel-casino.
Kahn says 5,000 or more people could take part, and the message will be heavily pro-immigrant.
The march began near Las Vegas Boulevard and Spring Mountain Road.
