Yes, it is not always an easy to thing to leave your country and your relatives but sometimes we have to and we move. So you have to decide what is more important to you - you new job in another country which you do not know or another job in your country. We always have an option

Alot here in my country (Philippines) would like to work abroad (count me in) but a few are given the chance to do it.First thing you need to consider is if you really want and need that job. Financial and self satisfaction. If you do, don't let your fear be a hindrance to it. We are all capable of adapting to new environment. Give it a try. Explore life and enjoy ;)

no i like to live in another planet like k_pax .

Sorry, I don't experience in this field, but here is what I think about it. First of all, you'll never know whether it's a good job or not while not tested it. Second, make a list of all pluses and minuses of the job, compare results and make a right choice :) Good luck! ------ P.S. Or are you just trying to find an excuse for your selected decision in here? :)
