Have a friend that works as an uber driver and he said he had an american customer was complaining that his Russian wife could not get a visa to come to the US and she is blonde and blue eyed (I guess Putin is messing it up for them)
However, you do want high IQ immigrants in your country so yes, they needs to be some selection. Eg. the high IQ indian IT workers who have now become the CEO's of google, microsoft, Adobe, etc and even immigrants like Musk (you want people like these in your country)
The latino's are good because they work extremely hard and do all the hard labor - construction, gardening, house cleaning, working on farms (America could not function without them)
But I pray that the US does not end up with those radical islamists you see in Europe that want to turn western christian countries into Islamic societies. America has been lucky to be blessed with the Hindu's, Buddhists and south american catholics.
