I have a bit of an odd visa/work permit question. (Late 2021 or 2022)

All this may or may not happen AFTER the covids issues die down. Next year or later. I just want to get an idea if it is even possible and how.

I would like to bring a consultant in to talk and give presentations. How does this work? Is he covered by the parent company to consult? What permit is needed? It will only be for 4-7 days.

I want to be able to advertise this as well so it needs to be on the up and up.

How do work permits work for say, competitive athletes? Motorsports? Etc etc.

My plan is to bring him in for a few days to do consults and maybe a lecture.

Where do i start?

Thanks for the info.
