It would depend on a couple of things:
1. In what capacity would your friend sponsor you? As an employer? Petitions can be filed by employers and close family relatives (spouses, parents, children who are U.S. citizens and in some cases, permanent residents). Friends as such don't qualify.
2. Are you subject to the two year home residence requirement? If you are, then you'd need to qualify for a very special status in order to not have to go home first. Also, if you are, to get most other statuses, including green card, you have to get a waiver of this requirement.

The above is only for information, is not legal advice and doesn't form an attorney client relationship. For that to happen, you would need to formally hire me and we would clearly agree in writing as to what you would expect and what I could provide you.
Sincerely,
