Unpaid Internship on H4 allowed?

[pri2nutrition]

Hi All,

I am on H4. I am trying to pursue Registered Dietitian course in US. One of the pre-requisites is to perform a six to twelve month long CADE internship.

Questions:
a) Can I do an internship while being on H4 visa? (Assume it would be an unpaid internship)
b) Does anyone in this forum have first hand experience doing RD and can help in guiding me through a first cut in the process.

Thanks so much in advance!

Regards
Priya
