Applying in O1 visa while being in the US (b1/b2)

Hi guys! As title says: does anyone have experience applying to O1 visa while being in the US for b1/b2 visa?

I have a company that can sponsor me and a decent case proving my “extraordinary abilities”. Have any of you been through the experience of working with lawyers to get o1 approval while you were in the US?

I know me and my wife (potential O3) will need to leave the US to issue the actual visa.
