Attracting the Best and the Brightest

To ensure that America continues to lead the world in innovation and economic dynamism, a Romney administration would press for an immigration policy designed to maximize America’s economic potential. The United States needs to attract and retain job creators from wherever they come. Foreign-born residents with advanced degrees start companies, create jobs, and drive innovation at an especially high rate. While lawful immigrants comprise about 8 percent of the population, immigrants start 16 percent of our top-performing, high-technology companies, hold the position of CEO or lead engineer in 25 percent of high-tech firms, and produce over 25 percent of all patent applications filed from the United States.

Raise visa caps for highly skilled workers
Grant permanent residency to eligible graduates with advanced degrees in math, science, and engineering

I have a few things to say about that here.. Romney says the US needs to import more smart people

Perhaps Mitt and the GOP/Tea Party want to outsource higher education to the developing world where it can be accomplished without taxpayer support through Federal and State subsidies, student loans, research grants, Pell Grants, etc. Also, because so many in the GOP/Tea Party promote anti-science views (see climate denial and Intelligent Design) the base is not opposed to offshoring the unholy business of advanced science education and research.

At any rate, pointing out the need to grant additional visas for immigrants holding advanced science degrees without addressing how we might improve the access to advanced education for our own best and brightest students points out how Romney’s priorities align with big business and not middle class Americans.
