Is the Amazon Prime Rewards Visa Card still no annual fee if you cancel prime?

Hi all – I currently have a 6 month student Amazon Prime membership and I usually just create a brand new Amazon account after the 6 months ends to get prime for free (we get tons of .edu accounts from school). I’m interested in using the Amazon Prime Rewards Visa since it has a generous $150 sign-up bonus. I can see that it shows there is no annual fee, but does this still hold true if I don’t have Prime anymore after 6 months? And if I end up closing my current account for a new email account after 6 months, how does that work with the card (can it be transferred)?
