Unfortunately, there’s no surefire way to prevent being selected for SSSS. However, if you notice that you’re getting selected repeatedly, you can find out what a redress control number is and apply through the Department of Homeland Security Traveler Redress Inquiry Program (DHS TRIP). If you’ve been experiencing frequent delays due to security screenings, this is an opportunity for the DHS to resolve any issues that may have designated you as a risk. Find out if applying for a redress number is the right choice for you, and note that it may take a month or longer for the DHS to process your application.
