This is an escalating humanitarian crisis as witnessed in other parts of the world in recent years. It rarely ends well if you follow up with those who live in countries where migrants have sought asylum. I have clients who tell me stories. Don't hate me but I would close the border to Mexico as the US is dealing with too many crises of its own and the caravans won't stop coming. No solution. Another US-bound immigrant caravan plans to leave next week from El Salvador. Among the travelers likely are pregnant women, who as immigrants face particular stresses in America.
