Be sure to bring a certified birth certificate for the ID. They will tell you it can take 2-3 weeks, but I got mine in 1. I dont know about your qualifying condition, but get it documented prior to coming out. From what I understand the card is not necessary unless you get caught, in which case, it can help you. If you have a recom, you could probably get it thrown out. I have my appt tomorrow, so I cant speak to the doc experience yet. Good Luck!
