Actually Mexicans go back and forth all the time. Due to the rigors of the very long trip Central Americans usually stay.Really? I posted an article from CATO that addressed this specifically. They’re called migrant farm workers for a reason. They used to come here for harvest season and then return home. When that crossing becomes more difficult they just stay here when there’s no more work for fear of not getting back in when work begins again. That’s not ideal.
