Some of us americans have been exposed to folks from other parts of the world, believe it or not. I learned this use of the word "queue" many years ago, though I would not use it to refer to people waiting in a line.(I am american, after all)...but I say stuff like "queue up" or "queless".
Lol.
Yes, many Americans probably know the term and its use, but we don't usually use it as a verb, because we tend to say "line up." Mostly, I hear it used as a noun in America, like when someone says something is in a queue (sometimes as an online term, too).
You also tend to hear it used more often as a verb among East Coasters, or others who are well traveled or well read, exposed to culture beyond that of the U.S. (many of us, fortunately, lol).
