Can I ED to UPenn and do non-restrictive, non-binding EA to other schools?

The Common App says “As we have done previously before, Penn will allow ED applicants to apply to other institutions that have non-binding admissions processes”

I know ? it’s right there. But I have a friend who did something like this, and had his admission rescinded.

So just for clarity, I can EA to schools like: Suny Poly, cal tech, UChicago… right?

Did your friend apply EA to a college whose EA rules say “no ED applications” (e.g. HYPS or Georgetown).

Read the rules of the EA college to see if it does not want you to apply ED to Penn or anywhere.
