Can one work for a ‘foreign’ company while on tourist visa? : immigration

I’m conscious of the restriction that US corporations can not convey folks from outdoors and have them work on vacationer visas. However are guests allowed to proceed their dwelling nation occupation remotely? Like if somebody works for an organization in Nepal, can he legally proceed to attend conferences along with his colleagues, create spreadsheets, do venture administration, write some code and so on whereas being a vacationer within the US?

I see this query is posted on stackexchange https://journey.stackexchange.com/questions/12771/can-i-travel-to-the-usa-while-working-remotely-for-my-non-us-employer nevertheless it looks as if a gray space.

Is there any official details about this?

PS: I had posted an analogous query lately, however folks should’ve misconstrued it as asking about working for a US firm.
