How Would You Feel About Hosting A Foreign Exchange Student In Your Home?

I am directing this question not only at Americans but at all nationalities who might read the question and have thoughts about the subject.
This year my family is hosting two students, one from Germany and one from Hong Kong, both girls. In the past we have hosted two boys from Germany, one boy from Korea, and one girl each from Germany and Hong Kong. This is our third full year to host, and we also hosted for a partial year.
Our son was a foreign exchange student in Germany for a year.
We have had exceptional kids to work with. The experiences have been incredible and we are connected to all of our past and present kids.
Would you consider hosting a child from a foreign land?
