Ted Pappageorge, who leads Nevada's largest union, the Culinary Union, with approximately 60,000 members, explained the unique position of the casino industry.

"In our industry on the Las Vegas Strip, it’s not an issue," Pappageorge said. "Well, it’s heavily regulated. Most industries are not regulated like gaming."

To work at a hotel with gaming in Nevada, individuals must prove their legal status in the country.

This can be done by providing a Social Security card for American citizens, or through legal permanent residency, Temporary Protected Status, or Deferred Action for Childhood Arrivals (DACA) for eligible immigrants.

"The idea of having state gaming control board and a state gaming commission and a highly regulated and having a high state of regulation for the industry, that’s never going to change," Pappageorge said.
