Explaination of codes
imwatcher123,
There are three types of codes on FP notices.
CODE 1 - FP only. The FP center will just take FP of 10 of your fingers.
CODE 2 - Biometrics Only - The FP center will take a digital picture, signature and FP your index finger. The Biometrics information is for the physical GC. This process used to be done after approval at the time of passport stamping but now the Service Centers are trying to get this done early so they can send out your GCs soon after approval and do not have to wait till the PP is stamped.
CODE 3 - FP + Biometrics - The FP center will take both.
Lately I have seen people get 2nd FP notices with either Code 2 or Code 3. infact my wife got a code 3 notice after she had already completed her code 1 FP in February. I am not sure if the FP center will take your Biometrics if your code is 1 but its worth a try. Might save you the hassle of going there again in case you get another FP notice with code 2 or 3.
Hope this answers your questions.
regards,
