I am an immigrant myself - so I have a certain perspective.
My main point is that an immigrant to any country has to be respectful of the people of the country immigrated to.
As for the caravans - it is not about people seeking admission to the US via lawful means - it's about the encouragement of certain factions of globalist ideologists in the US and other western nations, to be overrun by illegal, unvetted migrants.
Trump has said many times, people are welcome to come, but come legally. The vast majority of legal immigrants agrees. See my section on Legal Migration above.
