h1b visa for executive assistant

I’am a B-Tech IT Graduate passed out in 2011. I have been working as an Executive Assistant to the Director of a Pharmaceutical firm since then.
I have seen Executive Assistant requirements demanding a bachelor’s degree related to it,computers or business. So the question is whether US Corporations will sponsor h1b visa for executive assistants? Preferably finance companies.

Would I require atleast 5 Years experience for them? Are there any related work which I can do like business analysis with my experience.
