The Nerd's Eye View published a good article by Chris Stanley earlier this month about common mistakes regarding the Form U4. I typically recommend that advisers review their firm registrations and IAR registrations (including both the ADV Part 2B and Form U4) in October, in advance of the annual renewal process beginning in November, to ensure the firm and its IARs are properly registered in the right jurisdictions. But, as this article points out, the Form U4 is often overlooked. Unlike the ADV Part 2A and 2B, you don't have to give the Form U4 to clients, so you kind of forget that it's hanging around out there. Things that are commonly missed are updates to residential address and outside business activities. The article provides a nice summary and overview of the Form U4. Just for kicks, you can log in to your FinPro account (if you have one), or go to the IAPD website and search for your record to see if your information is accurate.
