… don’t host a student if you are short on money. Hosting a student costs at least a few hundred extra dollars per month. If you can’t spare that, then don’t host. Don’t put a student in a situation where you are always pinching pennies. You will also tend to resent that unknowing student, and that’s just not fair to them. Most of these exchange programs cost many THOUSANDS of dollars for the student and his family. Many scrimp and save for years or have to ask a rich uncle to help them out. This is a big thing for them. Don’t blow it for them, and be prepared to be somewhat generous. I think many host parents don’t realize the costs involved going into this (both in time and money), so I just wanted to get that out there so you can mull it over! (Life of a Military Wife)
