Hi there,
do you want to meet people when you arrive, or get in touch before landing?
If you live in a
condo, you will find that you will meet people pretty quickly. Kids are a great ice-breaker, and meeting other mums will follow on pretty quickly. There are also clubs around (there is a British Club, for example). If you are going to be a stay-home-mum, your kids school is likely to have something for mums in a similar boat - informal or otherwise. I have found it easy meeting people here - easier than home, sine most expats are out here without families or the usual support networks.
Otherwise, post your questions and concerns (we've all been there) and let the good members of the board help you out as much as we can!
