Exactly which sea does a Mexican have to cross to get to us?
Not *everything* can be blamed on Mexicans...
Probably the Rio Grande during flood season. LOL
“overseas” is sometimes used loosely to refer to any foreign country, even Canada. Seeing as the worker was from New York City, I suspect a better surmise might be Asia, Africa or South America, where a lot of unskilled immigrants come from in New York. Far fewer Mexicans and Central Americans in New York relative to other areas (it seems to me).
