For many Russian circus artists, their talents can often lead to an array of opportunities.

Opportunities such as consistent employment, the limelight and the chance to follow in their families' footsteps take shape. But these talents might also help some Russian performers in Las Vegas gain permanent residency.

But first they have to prove to be "extraordinary or exceptional" to the Department of Homeland Security.

In 2010, the Department of Homeland Security issued more than 3,000 extraordinary or exceptional ability visas to acclaimed scientists, athletes and artists.

According to reports, the application is a shoo-in if the petitioner has an Oscar or Olympic medal. Without such a major award, applicants must meet at least three criteria outlined by Homeland Security that prove he/she is an asset to the United States.

Many Russians like Igor Zaripov, fifth generation performer and aerial gymnast, have obtained this type of visa. He represents the best of a circus tradition that goes back more than two centuries.

And tradition is important for many of the performers applying for a green card. Life is about more than tricks on a rope or ice skating in a clown costume. It's about bringing a proud tradition from one country to another, where the pay is better, the audiences are bigger and the future often looks brighter.

"I'm the aerial gymnast on straps. So, basically, I'm holding the rope. I push myself in the air. And once I did it, I did a double twist. Nobody in the world does it yet. I had to prove to America what -- I am one of the best in what I do." -Igor Zaripov, Russian aerial gymnast.
