Attributing all the problems to those bodyshops is a bit disingenuous IMO. Yes they are part of the problem. Even Chinese nationals face 5+ years backlog for their green cards. Limiting immigration from populous countries based on arbitrary country caps for employment based immigration makes no sense. As it is it is a small piece of the overall immigration pie (14% and if we count only primary applicants, ~5%).
What is happening due to this is all advocacy to fix this has to be done by the folks in backlogs (Indians & Chinese) and the rest of the world folks can happily go about business as usual. Yes, H1 reform is needed but green card reform is needed yesterday.
All of the factors I listed apply to China. But even though both countries have similar populations, around two-thirds of H1B applicants are Indian nationals. Bodyshops are a big factor here. This flood of H1B applications is a big factor in everyone having to go through a lottery.
So if two-thirds of the H1B applicants are Indian nationals but the current system caps per-country green cards at 7% (per category), you see why Indian nationals have a much longer wait time than anyone else.
In saying that I'm not denying others (eg China, Mexico, the Phillipines) don't have long wait times too.
This is a great point that is rarely mentioned. China has larger population than India yet has a much shorter backlog so is it really the fault of the US immigration system that India has a long backlog? The Indian outsourcing industry and India’s lower level of economic development are parts of the problem.
