No it isn't. There are a lot of protections against beef imports into the US. So much so, that the Japanese were buying up ranches in the 80's so that they could better control the exports to Japan. They love their beef but have not land to do it.
With that said, there have been easements on production from Mexico and Canada.
Roughly 8 to 10 percent of beef consumed in the U.S. is imported from other countries, while 11 to 14 percent of the beef raised in the U.S. is sent elsewhere. The global beef trade is a complex web of supply and demand, based largely on the differences in what each society values from their cattle.
But fresh beef from other countries isn't very common at all. With 10% of all beef consumed in the US coming from foreign countries, how much of that is what ends up on your plate at Outback or on your backyard grill?

"In the world I see you are stalking elk through the damp canyon forests around the ruins of Rockefeller Center. You'll wear leather clothes that will last you the rest of your life. You'll climb the wrist-thick kudzu vines that wrap the Sears Towers. And when you look down, you'll see tiny figures pounding corn, laying stripes of venison on the empty car pool lane of some abandoned superhighway." T Durden
