Ukrainian Orphan?

Life just seems to have been a little bit too calm lately... so we are looking into hosting an Orphan from the Ukraine for a few weeks in January. The children come through in groups of 20-25 and stay three weeks while they try to meet as many potential adoptive families as possible. This group is mostly 7&8 years old but the range is from 6-12. We would only host one.  Its early days still, we haven't gotten all of the requirements (or responsibilities) yet. By the way the kids speak little or no English.
