Have you applied already?
I applied and got my letter to schedule a day later. I could have made an appointment the next day if i wanted.
Why do you need to do walk-in?
I haven't applied yet. I'm going to get his passport today and will apply right after I get it.
The reason why I'm asking about a walkin is because from previous experience, after applying for the rest of my family, I haven't been able to get an appointment for at least a month. This is in lax. I am assuming that in the NYC area it would be just as hard to get an appointment as soon as I need it. Unless you are telling me otherwise..
