A balanced discussion on the merits of the US H1B visa program. These programs exist in most developed nations, and the same issues apply.
As you would expect, the program is used to benefit some companies and abused by others:
Giants like Amazon, Apple, Google, Intel, and Microsoft were all among the top 20 H-1B employers in 2014, according to Ron Hira, professor of political science at Howard University who has testified before Congress on high-skill immigration. The other fifteen—which include IBM but also consulting firms such as Tata Consultancy, Wipro, and Infosys—used the visa program mainly for outsourcing jobs.
On the whole, modern IT is changing much faster and automation is replacing most of the tasks the outsourcing does today. The era of oursourcing ended about 3 years ago, it will take several years for the market at large to catch up to this fact though.
