You cannot work in F-1 status unless it is authorized by the school as part of CPT or OPT. Your really need to speak with an immigration lawyer to analyze your options. Your situation is complicated so you should not rely on any advice in a free forum such as this one. You may be able to switch to a different status such as E-2, if that is appropriate. This would allow you to run your own business in the US.
I agree with the lawyer, it is a complicate issue that cannot be adressed adequately addressed in this forum and all the answers she has given you.
Additional point to bear in mind is tha you might still be subject to the 2year foreign residency requirement and it is strongly advisable to contact an immigration lawyer for full assessement.
