Once you have received an approval letter you must appear at a DMV Hub office with the following documents:
Approval letter/email within 90 days of the approval date
Current valid Connecticut driver's license
Applicable fees for endorsement (this fee will vary depending on the amount of time left on your current license)
'S' endorsement only: Proof you have passed a proficiency test.
'V' endorsement only: Training certificate (R-360).
IMPORTANT: It is imperative that you appear as soon as you receive your approval letter.  All approval letters will expire 90 days after issuance date.  If you do not appear and pay for your endorsement prior to the 90-day expiration date you will be required to go through the entire background check again.
After presenting the above documents at a branch office you will be issued a temporary paper card with the new endorsement on it. This document should be kept with your current license until your new license arrives in the mail.  For more information on this, please see Central Issuance.
