Most Hindus here are professionals. The typical path to entry into the US is via an MS/MD/PhD in a US university, followed by an H1 visa working as a engineer/scientist/doctor, followed by a green card and then citizenship. Family-based immigration is comparatively rare. It remains to be seen (and could be a topic of further study) how well their descendants do. There is indeed a lot of pressure to do well in academics in Indian families (anyone who's watched the Spelling Bee competitions can see the disproportionate representation of kids of Indian descent), so it is possible that the subsequent generations will continue to do well; but it would still be worth studying.
