RFEs are very common, and since 2018, they are more common than ever. You shouldn’t panic if you get an RFE, but you should take it seriously. Most RFEs, when responded to properly, result in a visa approval.
Even if your case is low risk, you may still get an RFE. To lower your risk, consider increasing your bona fides before applying.
