@SlitheyTove I will definitely ask on the other forums as well!
The reason I am applying to a few safety schools is that I just want to keep my options open, in case I decide to try re-applying to the Ivies as a transfer student.
@rdeng2614 As far as I can tell, it seems that MIT is the only school in the list that considers international students who are American citizens (i.e. US citizens that have spent their entire lives in a foreign country) as domestic applicants. It seems that all of the Ivies, as well as Stanford, offer full demonstrated need to US citizens, regardless of international status.
Thank you again for your concerns and suggestions!
