No Interview - Deferred International

I wasn’t offered an interview and was deferred while 2-3 others from the same city were interviewed. Do I request them for an interview?

No, plenty of people get in without interviews. Do not ask for an interview. They will interview you if they want to. Some people get interviewed the day before results come out and get it. Relax!
On the other hand, do not count on getting in as a deferred applicant. Harvard defers more people than it rejects for SCEA. there is a 3% chance that you will be accepted as a deferred applicant, so be prepared to face that fact. good luck!
