I applied for a passport in 2011 and was initially accepted as I used my middle name as SIY. However when I renew this year I was declined due to my middle name I used. The person in charge in DFA said that I dont have to use SIY due to my mother and I will be sister.How ever I don't have any affidavit for now. What kind of affidavit I shall file especially the documents above I used SIY as middle name so that I will change.
