And as he himself said about his move to the US, there are grey areas sometimes with immigration. Having documents doesn't always make it "legal". Not having documents does not always make it "illegal".

Which is more likely to produce "the next Elon Musk," letting illegal aliens continue to pour into the country, or looking for those with skills, aptitude, and a strong work ethic?

Can't someone be both an illegal immigrant and have skills, aptitude and a strong work ethic?
