Hi and welcome to the forum. We're a diverse group here - a little bit from all over though I believe someone has recently turned up living in Eindhoven.

One suggestion for getting to know folks in your area (and in your situation) is to check out the FAWCO groups in your area. FAWCO is the Federation of American Womens Clubs Overseas - website here: FAWCO - Member Clubs

Although as an expat, you may not necessarily want to spend all your time with other Americans, the FAWCO clubs are a good place to start meeting people - and you can always branch out to local clubs later on. There may well be other English language or expat groups in and around Eindhoven, too.
Cheers,
Bev
