I just got my 6th renewal today for my B permit - the header on the letter says - "Ausweis B". I would like to apply for the C, which I can do as a US national. Can I do this with this form? I cannot see anywhere on it that I indicate I want a C, I have my criminal records check, my language test, and am trying to get a no social assistence letter... but do not know what to do. Any help would be appreciated.
