On the America's Got Talent (AGT) show, contestants that make it past the initial auditions held in various across the US are invited to perform in Las Vegas. All of those shows are taped and broadcast later.
The 48 contestants (this season anyway) making it past Las Vegas go on to perform at the Radio City Music Hall in New York City. Those shows are broadcast live, and voting by viewers determines who goes on to the next level culminating in the final show.
Obviously those contestants that win the first round of competition in New York and then go on to compete over a period of the next few weeks (if they continue to be voted through) have considerable living expenses, assuming they stay in the New York area to rehearse (or they might have a lot of travel expense if they chose to go back and forth to their home).
Do these final 48 contestants receive any sort of living expense or travel expense stipend from the show, or are they expected to fund everything out of their own pocket?
