I think currently this is a big caveat. Getting a work permit in other countries is not that easy, even for Americans or other countries with more prestigious passports. Maybe with AirBnB clout it is easier than without but I'd say it's still quite an issue.
That being said, I'm really excited for what the future could provide with AirBnB focusing on this. Maybe it will be easier not just for Americans and the like to work in other countries but I really hope it will be easier for others from places such as Africa and Latin America to work in Europe and the US as well.
