My name was correct on all documents but I did a change of address over the phone. I guess the person typed in my last name wrong because when I got the change of address notice the first letter of my last name was wrong. I called and they told me the same thing that I can get my biometrics done regardless. My change of address took 3-4 days for the notice to arrive, but the change of last name hasn't come in yet even though its been like two weeks.
