For me I dont think so even though I believe that going abroad will give me a great experience. I think Nowadays people can study from home because we can find alot of great resources and online courses. However I will go abroad if I want to study something really complicated or specific like medical but when it comes to learning languages I think its ok to do it online you can get most of it and maybe after your more confident then you can travel to practice what you study in real life.
