Immigration has been a hot issue in recent months, including debate between Congress and President Trump about border security that ultimately led to a government shutdown.  Is a wall immoral as some of the left have claimed?  How do people even immigrate legally to the U.S.?  Do Republicans/conservatives have a racist undertone when talking about immigration?
