Both my parents were immigrants, as were many of their friends, the parents of the children with whom I grew up. Of course I respect and admire immigrants and their undeniable contributions to America, as we all should.
The goal of immigration policy should be what is in the best interests of the American people as a whole. I would recommend limiting immigration to spouses and minor children of citizens, plus additional immigrants chosen for special skills needed in the U.S.
We should favor young immigrants with many years of work ahead of them. We should favor immigrants who have demonstrated an ability to learn and work using English, which makes their future success more likely.
If we want to set and enforce a limit on immigration, we have to be willing to say no to would-be immigrants who look a lot like our own ancestors, not because there's anything wrong with them, but simply because admitting them would exceed our legal limit.
