I took a piece of federal mail to show my change of address and my passport. They didn't look at either. I had my billfold stolen out of my purse and needed a new license with my new address on it. That being said I didn't have an appointment and because I went in during lunch I was allowed in to do my business.
I don't think that u can walk in. You'll have to make an appointment online. I'm not sure about the documents they will accept for identification verification.
