No one ever does, by that standard. In the US, if you're a professional coming in to do some short-term thing, there's no visa process. You just fly in and get the stamp in your passport, which is technically treated as a "waiver of visa". Then you do your job and go home.
Like, have you every flown somewhere to attend a conference and a meeting? Same thing. Where's the "authorization"?
