Last week I informed the 650 Dennery Rd. employees that lobby door was closed and locked before 7 pm. Today, when I went to check my mail box for my mail, the front door was locked at 6:14 pm. The automatic lock might be still set for Day Light Saving Time, which is no longer in effect. Please inform them to update their automatic lock of the lobby door to current time.


Excellent customer service at Otay Mesa Annex. Passport service at Otay Mesa Annex very fast and efficient.
