a) i have never worked in or off campus during my stay here, never had a SSN.One of the few potential pitfalls transitioning from F-1 to Green Card through DV are the following:
a) unauthorized employment - make sure you have all your CPT and OPT ducks in a row and well documented, in case you have worked any time off campus wile under F-1 and
b) overcoming "public charge" concerns - as you will be graduating by the end of the Fall 2015 Semester, check whether you will be able to present an preliminary employment agreement (another reason to apply for OPT, as this might help you to facilitate the former) and/or present other financial documentation to help you argue your case.
Other than that, you should be fine, presuming you have been all "clean" during your time preceding your F-1 status, as well. Again, best of luck!
b) my uncle owns a business and he will can be my sponsor, and also i can include a bank statement of my parents who support me and which is back in my home country.
I don't think that i have ever did an unauthorized employment, never got paid by an employer and never filed taxes. Just occasionally help my uncle here and there...
