Greetings from the Japan Alps !! I'd like to welcome you to the forum. I hope you will be able to come here and make your dream come true. It will be hard, but not impossible--I think.
At the university where I teach there is one student from Sri Lanka. He is now a third year student, I think. If you'd be interested in learning anything from him about what it's like to come here and live, I'll ask him if he'd be interested in communicating with you.
I moved this here because this is the better place for introductions. Thanks for your understanding. I hope to hear from you later ! MM
