What if owners of a company don't live or work in the same state as each other? What if they don't even live in the US?

i honestly dont know about operating a us company from a foreign country but if you have two owners in two states you would have a primary state where you incorporate and the other state you would set up a foreign corp (basically says one company is working in a new state) additionally you could choose a third state like delaware then have a foreign corp in each of the other states
