If you made an error and only realized it after you certified the application, you will not be able to correct it online until after your final interview. If you think you made an error that will significantly impact a decision to conditionally approve your application, you can submit your concern to us by clicking the "Submit a Complaint" option on the right side of the CBP INFO Center page. However, most errors are unlikely to cause problems so we urge you to wait until your interview to get it straightened out.
