Oh, I totally get why you love those countries. England, Switzerland, and Australia are known for their stunning beauty. Not only that, but they're also highly advanced countries that provide their citizens with all the basic needs and luxuries of life. It's no wonder they're considered some of the most advanced countries in the world. And the fact that they have a high happiness index is a big plus too.

If you had to choose one of these three, Switzerland sounds like a fantastic choice. Going there on a student visa is a great plan because it comes with many advantages. You can work while studying and receive a quality education. It's definitely an exciting prospect. Wishing you all the best.
