Do you think working abroad is essential for a successful career?

   I think that working abroad is not essential for a successful career, because your career depends on your training, personality, interest of each person. However, I agree that working abroad may be worth it, due to the fact that it means to have  knowlegde  of other languages.

   On the other hand, it has disadvantages too.Apart from mastering the language, you must know the culture of the country, because it can cause some problems or confusion, and you will feel homesick :( .
