Why need an expat communities?
I always heard from others foreigner say that they feel they live in a separate community from local community. Why this happen? Local separated you? Or you seperated yourself from local?
Its was a lot of fun and fantastic feel if you can "well mixed" with local for the place you travel to, live in.
Just ask yourself, what your initiate intentions to work at others country? I think most of the expat with say to gain more experience, wider self view...blah...blah...
If you are looking for something same with your current or pervious, then why travel or leave your current environment. No point, is it? If want to get similar in others place, I think it much more easier if you just keep your current. Don't need to leave your family & friend behind.
So, why not penetrated yourself into local community?
Maybe you want maintain your living standard, then select the standard you need, but try to mix with the local at least.
I didn't mean to or intented to hurt any people feeling but to voice my own view. I am not a local but enjoy with mix up with local. Sometime happy ,sometime sad , sometime angry . THAT'S COLOUR OF LIFE!!!
