Actually immigrants, especially illegal immigrants, on average commit far LESS crime than natural born citizens, specifically to avoid potential deportation. The "immigrants are criminals" narrative is older than America and you'd have to be pretty f**king stupid to fall for it.
Also the Constitution literally gives rights to EVERYONE in the country, in unambiguous terms. Not as many rights as citizens, but they definitely gain the right to a fair trial, and the right to NOT be taken to concentration camps.
