Hi all,
Hopefully I can clear some things up about orientation. You will be doing all orientation activities with members of your program site. Other program sites that share the language that you are studying will not necessarily have the same orientation dates (and frequently do not meet), and you will probably share some of the bigger orientation events with members of other program sites/languages. For example, last year, there were three languages doing orientation in DC at the same time as me (I did Turkish, and there were Russian and Indonesian groups doing orientation at the same time as me).
When orientation is over, you go to the airport (and your final destination city) with students who share your program site.
