There are many, many languages being spoken along the southern border right now. Gone are the days when it was just a bunch of Mexicans.

Right - now it's a bunch of Venezuelans, Colombians, Ecuadorians, Guatemalans, Nicaraguans, Hondurans, Paraguayans, and Cubans. Wonder what they all have in common, linguistically?

There's a smattering of people from everywhere - but the only large volume countries are Latin American. The only country with any volume that doesn't speak Spanish is Brazil. Everywhere else is a rounding error. And the places that are Arabic-speaking are a rounding error of a rounding error.

Showing up with no identification speaking Arabic and claiming to be a Yemeni asylee is as dumb as can be. You submit yourself into government custody, give them the authority to indefinitely detain you, shine a big spotlight on yourself instead of trying to blend in with the many thousands and thousands of Arabic-speaking tourists and businessmen that land every day at our airports, and subject yourself to a review process that requires skill and persuasion in an extended one-on-one interview which still might keep you detained because you are a rare case of an Arabic-speaking asylee with no ID.
