Student Exchange Programs

I’m 15 years old, with 3 older sisters (30, 25, 24) big age difference, i know. Anyways, we would either be getting a 15 year old girl from South Korea or a 16 year old girl from Germany.

I would just like to know what are some things my parents and I can do to make her feel welcome. She’ll have her own room, and we’ll share a bathroom.

Also, what are some good/bad experiences you’ve had (or heard about)?
