OBC Non creamy layer certificate

Sir, I am currently residing in West Godavari district, Andhra Pradesh and I belong to BC-D category with caste Turupu Kapu. Previously my forefathers resided in Vizianagaram district, Andhra Pradesh and my grand father used to live in that district long time back. We have been migrated to West Godavari district and residing there since my childhood and I had the migration certificate from Vizianagaram district MRO office as well. As per the list of reserved communities issued by the Central Government, my caste (BC-D category with caste Turupu Kapu) is not listed in the district of West Godavari under OBC category and it applies only to the districts of Srikakulam, Vizianagram & Visakhapatnam districts of Andhra Pradesh as per the Gazette Resolution 12011/4/2002-BCC dt.13/01/2004. Could you please help me with the below questions ? 1) Can I apply for OBC certificate in West Godavari district since I have been migrated from the Vizianagram district which gives OBC certificate for my caste (Turupu Kapu)? 2) Are there any other documents needed for obtaining the OBC Non creamy layer certificated in the current district I stay?
