I just received my Naturalization Cert. today and found out that my signature on the photo only includes my first and last name, and it's so casual that the letters are unrecognisable. I requested a name change at the interview and now my middle name is included and printed out on my Naturalization Cert. How should I sign my Naturalization Cert.? (In new full name, or a "recognisable" version of my signature on the photo, or the casual signature on the photo?) Please advise. Thanks!
