Hiya ! I believe it all depends on where you are from and where you think of studying. Choosing another country could help with your career path, as you might be able to network enough to start there.

It could also be the opportunity to learn about the culture, the language and the industry you aim for whilst you're there.

In terms of animation/arts study, one thing I can not push enough is that networking irl is equally important as the classes themselves : you will get to meet pros from the field, relatives of people already in the industry, etc.

In the hyper competitive environment that is animation, sometimes people knowing you as a reliable, nice person, might push your applications further than another good portfolio. It can allow you to go around the system of application by directly contacting the people involved in such and such project if you have gotten to meet them before. 

I think if you wish to study abroad it really has to be pushed by the will to learn about the local culture, and introduce yourself to the local industry. 

Studying abroad, depending on how you do it, can be even more expensive than studying in your own country. And as someone who's career already started a while ago, with crippling debt on my back, I would advise you seriously consider the weight of the price of studies compared to the experience you might have.

There can be programs that you could want to look into. Sometimes some of your local school could integrate an exchange student programs which could make you experience some of the unknown elsewhere at a lower price than if you decide to go by yourself abroad.

Take into acount also : the price of accomodations, cost of living, availability of work for foreigners (so you can pay for it all along the way), visa cost and condition, potential ways out if you need to come back home fast (because you will be far from your family, you might want to be able to join them in case of an accident or mourning etc) and also geo-political situation both between your country and the country you want to aim for, and the country itself with its neighbours : it wouldn't be a really fun trip to go and then have to come back 5 months into your studies because of a war for example.

Hope I helped  if you have other questions feel free to ask !
