Hi @FedeCaivano, I'm glad to hear you're looking to expand your audience on Udemy.
One thing you might want to consider is offering your course in English. Changing the course language will affect how your course is discovered on Udemy, and your course will appear with other courses taught in the same language for students in that region.
You may also market your course in different groups and social media channels, this page has more information on how to do this.
Hopefully, other instructors can offer their advice in this thread too. All the best! 🙂
