In the long run, the engineers trained via outsourcing will become strong competitors, while USA have nothing to compete against then. USA can not have all the local graduates do architecture-design or marketing/project-management,that will doom the country soon or later.

Usually H1Bs' kids excel at school, and their parents pay tax on that. For their poor relatives to immigrate 22+ years later(roughly 5 year for greencard, 5 year for citizenship, 12 years for relative immigration waiting period), it's a immigration policy issue, however it's still all legal, at least 10X better than those who came here illegally.

Keep jobs local is vital, outsourcing R&D is so short-sighted, with more STEMs, H1B will be irrelavant.
