F1 student visa? Then yes, keep the F1 visa until you receive a decision on your I-485, so no matter what the result is, you'll not fall out of status.

you have to maintain an active status until you file your i-485.

if you’ve filed for AOS you don’t need to maintain F1 status, but if you for some reason get denied then you would probably have unlawful presence. if your case is straight forward I wouldn’t worry about it

whats your FO? how was the interview?
