I've found making friends abroad is fun and surprisingly easy to do. While researching living abroad I asked a lot of questions of expats using the on-line sites. I've found numerous Facebook groups in many cities in many countries. I don't only want to connect with Americans but Europeans, Asians and Africans too and it's amazingly easy. Folks really want to be helpful and go out of their way to answer questions and make suggestions.
If you're not sure if you want to live abroad but are thinking about it some excellent sites are available online and you can make friends before you even leave home! My suggestion is to simply search for the country and/or city in which you are contemplating and see what expat sites are available.
By the time I actually arrived in Nicaragua last year I had friends on the ground and you can too! I would also consider several trips to your country of choice, either alone or with a group just to get acquainted with the culture. Of course, we here at Finding My Place would love you to join one of our Group Journey's to get your feet wet on how to explore and what questions to ask yourself.
My next stop, Nicaragua then Thailand, Malaysia and who knows where else. Happy friending!
