Came on a Friday morning at 8am (when they open) and the renewal process took less than 40 minutes! The office is very easy to find, there are signs from the front leading you to the third floor and lots of arrows. The procedure is now two step - in first room where you go to get a number, the officer will check your documents to make sure you filled everything correctly. He even caught some boxes I missed! Thanks! In the second room, you wait for your number to be called. There were at least 6 officers there, very efficient. Im just glad it was such a speedy process I finished early enough to make it to work on time!
