Born in Spain

Hi all
I was born in madrid, Spain. After a few years of my birth my parents returned to india along with me.
Now i will like to go back to spain and apply for my citizenship.
As i was born in madrid , can anyone please guide me with the exact rules?

As far as i know i have to stay for one year in spain , before i can apply for citizenship.

Thanks in advance

Being born in Spain does not automatically make you a citizen.

Your first step should be how can you qualify for immigration/permanent residence in Spain.

Where do i get that information from?
I can't go as a tourist. Unless i have a workpermit i can't apply for a job there. The first thing i will like to know is that how do i get the permission from the spanish government to stay in Spain for atleast one year and work there?

I sincerely hope that you all can help.

Thanks
