Traveling and massaging would seem difficult and very expensive. Yes you can massage anywhere, but keep in mind you need to of already had the education for that particular area and the Board may reject U.S.A. schooling credits and license. Like say you took a 500 hour Massage program here, and wen to England and found out there's is 700, you'd be in a tight spot. Pick a few places you want to massage, Africa, Asia, etc, then narrow down the area. Check with the Board in those areas and apply for licensure. This would be the only way, I'm sorry if this doesn't help you much.
The world does not pay for your education and knowledge. It pays you for what you DO with that knowledge.
It is not the lawyer who knows his law that wins the case. It is the one that PREPARES his case that wins.
