Hi Ao,
Thanks for checking in. You can list either address on the application as a hard copy is not sent to a home address, you'll only receive one via email. The majority of first years will be working as per the terms of their fellowship offer. A few will not be working as they have other fellowship awards that do not include first year employment. Let me know if you have any other questions. Have a great weekend!
Sincerely,
Vicky
