First of all, a great advantage of living abroad when i finish my studies is that i would learn another type of manners and another gastronomy. On the other hand it would also be good since i would learn the language better.
Secondly, a disadvantage for me would be overcome my fears, because i am not capable of to be far from my family and therefore i would have commute to see them and that would be a lot of money. Another disadvantage is that you should look for work in a place where you do not know anything, even at the beginning you should be living with another host family until you can become independent.
To sum up, i think that going to live in another country is based an open mind and being capable of to face all the consequences because the conditions you may not like.
