Incoming BB Summer Intern – Still Have 2 Years of Studies Left. Disclose or Not?

Hi everyone,
I'm an incoming summer intern at a bulge bracket (IB division). I still have two years left before I graduate. I’m wondering if I should disclose this timeline to the bank now, or just focus on doing well during the internship and address it if/when the return offer conversation comes up.

Also, how likely is it that banks extend return offers for someone who won’t be able to return full-time immediately? Would appreciate any insight from those who’ve been in similar situations or seen how banks handle this.

Thanks in advance!
