Hey, great news -- I have a Placement Officer!
This morning, I called the placement office at the Peace Corps headquarters in Washington DC. I left a voice message, asking if I could find out who my Placement Officer was. About five hours later they called back with the name of my PO -- wow!
I know they are very busy, so I was very surprised by (and happy about) such a rapid turnaround.
From my understanding, my Placement Officer will ultimately be the person that decides if, where, when, and what I would be doing as a Peace Corps volunteer.
In a careful attempt to tread the fine line of being proactive without being a nuisance, I sent a "Hi, it's me" email to my Placement Officer.
