DREAM Act Portal Forum - Walk in bio, in Philadelphia experience

I decided to do a walk in for my biometrics a week early then my scheduled date, due to I would be working the day I was set to go. Decided to do a walk in a Friday morning took the turnpike wich was 20$ round trip 1hr drive and got there a couple minutes after opening time. The guard was a lady I gave her my slip she said today is not your scheduled date and time and we don't take walk ins. I responded I know I just wasn't going to be able to make it next week I work and she responded well read the paper you were to contact uscis so they can give you a new appointment, at this time I just stood quiet she threw my paper on her desk and said have a seat I'll see what I can do. After she took care of the rest of the people in line she called me up and gave me a form to fill out and let me get my bio I thanked her and she responded yea we try to help each other out :)
