My chapter did pledge a student from the UK who was studying abroad at our school for one year. She was an AWESOME member.
Frankly, we pretty much knew we were going to get her because most of the other chapters probably wouldn't pledge her because she was only going to be around for a semester (we had deferred recruitment). It's sort of similar to the philosophy of, pledge freshmen rather than juniors because it's two more years of tuition.
We never regretted pledging and initiating this member for one second though!
