I'm sorry if there are similar posts, I had a look and couldn't find something exactly similar.

I will be starting my final year of Bachelor (in the UK), and I am going to start applying for an integrated MS/PhD in mathematics (in the US). Recently, I started thinking about going for a gap year before starting with my graduate studies, and I found an interesting (but very selective) internship which might be interesting.

However, my problem is, I do not know how the admissions process works for the internship. So I might end up getting an answer **after** having sent my PhD applications. So my question is: is it possible in some universities to ask for a "possible" defferal of admission? Conditional on a third factor?

*PS: the universities I am applying for are UC Berkeley, and UCLA. I was thinking of emailing them but thought maybe someone would already have been in a similar situation here - and could maybe give me some advice :)*
