Advice on employers for Math and Physics majors

Dear all,

I am trying to help a friend who is in this predicament. He has a M.S. in Math and Physics. North Eastern States are fine. Currently, he is in Virginia.

Please share, if anyone knows any employers who (after hiring him) will be willing for supporting the employee, for work permit.

This will be immense help on your part if you can share any useful information on such employers in math and physyics field who will be willing to support him for obtaining work permit in America.

Thanks,
