that you find someone (even a not so close friend or relative) you know personally before going here. Just to make sure someone will look for you just in case. Now, if there is really none, then you need to be friendly with the first people you will work with (work colleagues), for sure they are the only persons (initially) would make your life a little bit comfortably for your starting days. Good luck! You will need a lot of it but if you are a strong person, then you'll survive, that's for sure!

BTW, don't listen to drunkards, they won't say anything good to you!
