Need Help regarding renewing my Residence card. i dont know what to do.

Hello begal users and admin,

I am Lavi Chand , living in Barcelona from last 3 years .I am a little bit confused about the situation .
I am 20 years old now . I was 17 when i came to spain . When i came here , as my father has permanent residence(expiring in 2015 ) , they issued me residence cards for 3 1/2 years (expiring on the same dates as of my father). i am still living with my father . as, i am renewing my first residence card thatswhy i and my father ,we are confused about the process to renew my residence card .
do i need to subbmit my all documents at a regional office and need to wait for the finger letter or i can give my Finger prints with my father directly without subbmitting any kind of documents ?

Awaiting for your response

Regards .
