After rereading my last post, I think my intent wasn’t entirely clear. The parents get deported whether they choose to have the kid stay or not.
I understood what you meant. And most will take their children with them.
Which is exactly what happened when Eisenhower had the braceros deported in the 1950s.
Many had citizen children, who went back to Mexico with their parents. Some came back as adults, as they had birth certificates to prove their American citizenship.
I met one such citizen years ago during the Prop 87 campaign in 1993 in California. He was FOR it, and felt that Immigrants should come here LEGALLY.
