People are nowadays going abroad to work. Or at least, to try to find a job. The main reason is because there are a lot of qualified people who has perfectly ended their career but there are just a few opportunities for all them.
I believe that going abroad can increase your personal experience. In fact, you can improve your social skills making new friends and traveling with them on weekends to visit new places and gain knowledge about the new culture you are living on.
Another factor is being able to speak in other language because you will have to deal with other people or colleagues at work to interchange your opinion.
Finally, to put a professional point of view, working abroad can open a new window when you will be back in your country. Because of this whole experience you will have improved your CV.
To sum up, despite you will miss your family and friends, you have to think about your future and working abroad is one way to develop yourself professionally.
