Can I renew my passport even though it doesn’t expire till November? I need it for my visa. I’ve paid and already have my passport interview date.

You can. By the book, you renew when you have 6months and under left on your passport. Otherwise, you will need to explain why you wish to renew with more time (6+months) left on the passport. Your renewal shouldn't be a problem but I'd say be ready with that explanation in case it comes up...which in your case is a visa. Visa issuing authorities usually require that passports be at least valid for 6months..., so you've got your explanation.

I believe you can. You call the front desk to find out too.
