My application is probably a bit strange, but I studied math at a small German university which accredited in the US as well. Finished in 2015, and am currently at a masters program in europe that i am trying to get out of.
But i did have a Skype interview with a prof from the University of Buffalo last week, in the Mechanical and Aerospace engineering department. so thats probably good
He told me to expect an email in the next 2-3 weeks from the university....
hopefully it works out
Other programs I applied to:
UCSD Mech Engineering/Aerospace
WPI Engineering
Columbia University School of Engineering Applied Math/Physics
and some other non engineering programs
