Can you tell us what school he is at, at what his citizenship is? Does his school have a coop program that he can join? Are there summer internships that he can apply to?
One option is to keep his grades as high as possible, graduate, and then work for a couple of years before applying to grad schools. This worked for me many years ago, but then I might have been very lucky in terms of what sort of work I was able to find.
I don’t see the point of graduating early. I am thinking that if a student stands out as being both a really top student, and being a pleasant and responsible person, then some professors are likely to notice.
Another option is to transfer to a school that has better research opportunities. However, it is not easy to predict this ahead of time.
One daughter is getting great research opportunities as an undergrad student. However I do not know how much of this comes from being a very strong student and how much comes from being at a small school where there are very few graduate students, which allows undergrads to participate in research opportunities.
