You can tell how ignorant you are and the lack of reading you do when you state that people with such visas are taking your jobs, fact is those visas by law cannot be paid any less than a qualified citizen so your argument here is quite erroneous. You want Trump for president because he promises to make America great by building a wall? You truly believe he hasn't benefit from illegals or does business outside of the US because it's cheaper? By God don't be fooled, I do hope that if he wins he proves many of us wrong. This presidency has a lack of talent I am a republican but Trump by no means qualifies as a republican. Racist, biased, unapologetic, egotistical man and fooled of it, that definetly does not equal conservative. And as an FYI look at those top Universities here many of its teachers are foreigners too so it's not just the students and it's not the book and the school that makes one great it's also the kid that has a great mind and fights for a better self so yes this country wouldnt be what it is if it weren't for immigrants too, not all immigrants are great of course but not all American are either so just like everything in this world there is a balance. And the world is what it is because of people immigrating or you think America was created by its local native Americans only? We all come from some place else, your ancestor may have been here before but that gives you no more rights than any other "legal" immigrant that comes to this country. So stop blaming immigrants for just the sh--ty results of the US it's society itselt as a whole.
