Stanford seems to place a lot of value on them. What about H & Y? Other T14 schools?

Thanks!

Hi,

I'm pretty set on putting in applications for this application cycle, but know there is a possibility I would want to defer or re-apply during a later cycle so that I can continue to pursue other goals. I'm wondering how declining admission to a school (T14) would impact a later application. I have heard that declining admission if you got off the waitlist looks very bad. Are deferrals ever granted for 2+ years? How soon after receiving an admissions offer does one have to make their decision?

Thank you.
