My tourist visa has expired a year ago and ive been without status since then ( I was wrong i know) but now the owner of the company i work for would like me to stay and legally work for them, he is willing to sponsor me. Question is, how long does it take to get a visa for work while in the united states already? Is it even possible? Thank you.

Any bigoted "illegalzz get out of the countryy" comment, please dont even bother. Im looking for some knowledgeable answer.
