When Kansas State’s point guard Angel Rodriguez (who’s Puerto Rican) went to take foul shots some in the crown started chanting "Where’s your green card?"

Think Progress with more details:

During their school’s NCAA Tournament game against Kansas State University today, members of the Southern Mississippi University band chanted, "Where’s your green card?" at a Puerto Rican Kansas State player.

Kansas State guard Angel Rodriguez, who was born in San Juan, Puerto Rico and played high school basketball in Miami, Florida, was fouled while shooting during the first half of today’s game in Pittsburgh. As Rodriguez stepped to the foul line, the chants, reportedly started by Southern Miss band members, began.

The irony of it all is that those born in the Commonwealth of Puerto Rico are actually U.S. citizens.

(The chant may be tough to hear without earphones.)
