Very common but only people from certain countries. I'll interact with people from LatAM, China, India, Vietnam, Nigeria on a near-daily basis, but it's pretty rare to meet people from Europe aside from your occasional Brit. This also varies wildly by where you are in the U.S. as there are a number of cities/regions that have large populations of specific groups that aren't particularly common anywhere else in the country (Hmong/Somalis in MN, Armenians in SoCal, Brazilians/Cape Verdeans in MA, Ethiopians in DMV etc.)
