M.Sc. Biotechnology (U.K.) validity and jobs in USA

Hi Everyone,

I finished M.Sc. Biotechnology from East London University.
I moved to USA on H4 visa and I am about to get EAD soon. 
Could anyone tell me
1. If M.Sc. UK degree is valid in USA for jobs?
2. Do I need to do any special courses to get job in USA?
3. Please let me know any employers or consultancies that offer H-1B visas for M.Sc. students who studied in U.K.?

Any information is greatly appreciated.
Thank you.
