"Highly-Skilled Immigrants"

[politicus]

There is a PC answer to this question which is: Immigration is good and everybody benefits from it. So it will be difficult to debate in a rational way, but Ill try.

When rich countries attract experts from poor countries they hamper their development if those immigrants don't return. Yes, they send money back, but they don't use their skills to improve their home country and the investment the poor country made in their education is lost. An Indian doctor in Los Angeles cant cure Indian patients, simple as that.
Its true that lack of infrastructure can make it hard to use high tech skills in some countries, but if the experts leave, those countries have few chances of developing that infrastructure, so that's a poor argument.
The US should focus on educating the talent mass among its own underclass and lower middle class by giving them free college tuition and grants instead of harvesting talents from poor developing countries.
High skilled immigration is basically just another way rich countries exploit poor countries. Its good business for the receiving country, but don't take the moral high ground if you support it.
