A related effect happens after you move. In your first months in a new place you can easily seem interesting and get invited to parties and whatnot because you're new in town. But you're like an animal in a zoo: look at him, so unusual, oh let's move on to the next one.

The people you meet will usually be longtime residents of your new home. They have evidence that your friendship will not last, because after all you just told them all about the place you left behind. You'll probably leave this place behind someday, so becoming deeply involved with you is likely a big waste of time.

Don't worry, there's an expat meet-up every Wednesday! We have no idea who will be there, but maybe you can meet some new people!
