As the previous responder noted, an appointment means waiting until September. Walk ins are allowed, get there as early as possible. By 8 there is a line in front of the door. Depending on how crowded it is, they can check your documents and give you a text message telling you to return later that day or the next.
I went at 6.30 and there were 10 - 15 people in front of me waiting already. I was called in at around 9.30, I came out by 10.30 or so. Note: Saturdays are only for Walk ins. So you can expect more crowd and delay on Saturday.
I recently went as a walk in but had to come back because they stopped. Came back the next day around 1:30pm & was out of there by 4pm. Didn't have appts until sept. Sorry but you'll just have to take ur chances as a walk in, unless you want to wait a month & 1/2.
