    This location is right next to a rail road crossing so when a train is passing (not sure how often that is) there is a line of traffic blocking the main entrance. Luckily, I was able to enter the City Hall lot (not connected to the post office but easily walkable) I parked, went in to mail a package, and left before the traffic even budged. At the Post Office, one customer was being helped in front of me but another person came out from the back when they saw me waiting (a minute maybe) and helped me right away.

    She is not polite and doesn't listen to you. I sent an overnight package and arrived two days late. However it was written money guarantee in case of delay, I had hard time discussing this issue with them.

    The staff was friendly. 10 AM was a good slot to get the passport application done. There were no queues. Good to have a appointment so that your application is on priority once you walk-in. The parking is ample behind the USPS office.
