Nothing new. They’ve been coming across for years. They’re referred to as OTM or Other Than Mexican.
Yes they have and when you got them on the ground, you could tell them from the Meheecans.
They stand out like a black bean in a sack of white beans. Remember one that got very irate that we cornered in a mesquite flat with a group of 20 or so. Challenged him on nationality. Would not say a word, just glare at us. Dude was peeoed to the max.
