As a long time IT worker and manager, I don’t blame the Indians, Chinese, Koreans, etc. for doing all they can to work in the US. Having worked with literally hundreds of them, I find that their real goal is to escape the 3rd world ratholes back home and bring as many of their family to the US as they can. They work cheaper, longer hours, never ever complain and for the most part are ideal workers from the company perspective. But hundreds of thousands of Americans cannot find a job because of this system. Common fact that Hillary Clinton has taken big donations from the offshoring firms. Hopefully Sessions can stop this from expanding.
I have found that their work product is not as good as Americans. Asian are the exception. Every place I have been that has an offshore contingent we would spend the first part of the day fixing what they worked on overnight. They are fine at a theoretical level but have a hard time translating that to an actual product. We were always in “design” mode.
I have also noticed a trend in the Indians. They job hope every 18 month to 3 years and if you follow their resumes they are touring the US while working and sending money back home.
The quota should expand and contract with the economy, and for many years it did. During the 90's IT boom the quota had expanded to close to 200,000 per year but following the post IT contraction the quota fell to 50,000.
It was during that time that the anti-immigrant wave swept thru the GOP and even tho the economy would expand, the minuteman republicans would successfully block attempts to expand the quota.
Then the economy collapsed and there was no need for them. Now with the recovery, they again want to expand the quota.
This is the best part of guest workers, you can expand and contract as needed. This also the best part of a dual use visa like the H1B. You get to test drive the guest worker before you allow him to convert to the permanent visa.
