I'm assuming you would be looking to obtain a MS or PhD degree in physics. If that is the case, generally if you are accepted into a program you will receive support either as a Teaching Assistant or a Research Assistant. There are very few, if any, "scholarships" for graduate work but there are many "fellowships" that are VERY competitive.

I would look at schools first. Then talk with them about what financial support you could expect.

Also, I've taken the liberty of editing the title of your post so that it is more descriptive.
