Everything will be fine. Very well organized considering how many people they process a day..... you come in, get your number, will be called to make a line, get your papers (few of them), then will be called again to return your papers, after that will be send to take D/T, come back, tell them you took your D/T. Wait for another letter or the call after that.
Should be out by 10AM. They work fast, good and professional people, no complaints. They will help you with any question you have.
