Why not hire completely international then?
Having a team completely unavailable during the USA working day is a real pain for collaboration and it's hard to sue people in other countries that "borrow" your source code to make their own version. Also, knowing exactly how to pay (say) a German developer and how taxes work and what the labor laws are is always an issue.
Aside: The very best contractors I ever hired were Ukranian. So many absolutely fantastic talents at around $30 an hour. Then Russia invaded (the first time) and annexed Sevastopol and the USA made it illegal to pay them any more.
Of course, people realized that and there's 0 unemployment in IT, however, there's still a long way to go before we get to the Bay Area salaries - 6 figure salaries are only for the top 1% devs and only working for the USA and usually short term contracts, but a decent developer makes north of 50.000 dollars a year which is a pretty good salary here.
Shameless plug- a buddy runs a dev shop out there, they have great devs and exceptional designers (and also are doing a fund for Ukrainians impacted by the war). If you're looking for help in that region, they're great people to chat with: https://beetroot.co/
only ones who stayed in Crimea
2. english language barriers - half the people I have worked with in South America (Colombia, Brazil) and China were so bad with English that it seriously affected the team's productivity.
Canadians fit the bill on both counts - same timezones and language.
