@Olivia538 I'm not sure what you mean by "host status rating," but in terms of Superhost you aren't penalized if the guest chooses not to review you. The only thing is, the more total you have, the less of an impact an individual rating will have on your averages - which can affect your Superhost eligibility.
Airbnb does email guests several reminders to leave a review, and they also get a notification when you complete a review of them, so it's not really necessary to prod them any further. But some friendly correspondence on the checkout date can help keep a pleasant vibe fresh on their minds when the first review prompt comes in.
