Just did mine:
I support this extension of OPT.
Some people with the zero-sum mentality believe that there is a limited
number of jobs and they will loss jobs to foreign students. True, foreign
students take jobs. But they also create jobs as 1) end consumers of
products and services, 2) future entrepreneurs who will form innovative
companies in the US, 3) future entrepreneurs in their home country with
strong tie to the US.
