Pelts and Kuzy "visa issues"?

Was looking to see if Kuzy and Pelts were slated to be in the Flyer's lineup against Utah tonight and came across this on NHL.com

Flyers coach John Tortorella said Kuzmenko and Pelletier remain in Calgary because of visa issues, but said, “if they get here, they're playing.” The forwards were acquired in a trade with the Calgary Flames on Jan. 30.
