Yes, Amazon's Kindle Direct Publishing platform allows most people in the world to publish a book on their platform.  In the Mastering Book Publishing course, we have members from many countries outside the USA, including: Canada, United Kingdom, Australia, New Zealand, Germany, France, Mexico, India, and everywhere else you can imagine.

Keep in mind, the biggest market for books on Amazon is inside the United States.  That means you have the potential to make the most money if your books are in English and targeting customers in the United States.
