If I am a Contractor, can H1B be sponsored along with Green Card?

Hello forum,

I am graduating in May from a New York Dental school after doing dentistry DDS. I found a dentist who is willing to hire me as a dentist in his practice ONLY as a CONTRACTOR and NOT as an Emplyee. He is comfortable to sign in all the paper work that may be required for applying for H1B and Green Card. 

The practice where I will work has been there since last 20+ years and he is a dentist too. The whole practice has a gross revenue of 2Million USD. 

My concern is: Can he actually sponsor me for an H1B and Green Card, even when he calls me the contractor in the service agreement? (Although I work like an employee, 40 hours a week, and he lets me use all his instruments, staff and practice and what not?)

Would it be legal and would there be any problem while H1B or Green Card is sponsored when i am working like a CONTRACTOR?

An H1 is for employees only. A GC also required a full-time employment offer.
