manta

Im on a 10 year multi entry b1.b2 visa south african passport.I applied for extension and am still waiting(pending although the date is up)I have a job offer that is specifically skilled (the owner will create it to suit my skills)Im a qualified quantum touch practitioner(energy healing with animals in particular).Im still in the us and my 180 days will expire in 1 month-how can i stay in the states and become legit and start work-do i change status to eb3 ?-my potential boss will sponsor me and do what it takes to keep me here,my country is a mess and it just doesnt work for me anymore and my skills are better here and not many american have the skills yet here that i have-which i can train however i dont have a degree.Is there a processing fee and if so how much? -is there a alternative way i can do this-or should one just pay to make sure its done properly,which im hesitant to do?So basically what are my options to stay and not return to south africa ?thank you
