TSA’s goal is to provide you with a response within 30-45 days of receiving the information you provided at enrollment. This may take longer if there was difficulty capturing your fingerprints during enrollment.
If cleared, you will receive notification by untracked first-class mail. Your letter of clearance is for informational purposes only and should not be required for proof of clearance from an employer or state. TSA sends official notification to your state of license only, and your state reflects your clearance result when it issues you a CDL with HME. Please check with your state as to what it may require you to do once you receive notification from TSA.
