Hi Sir/Madam,
Please bear with me i have much to explain about my case.
My mother has married to x-husband, then she had a daughter and x-husband died. Then my mother married a y-husband, then she had 2nd daughter and a son(Its me). Then there were some issues with y-husband, then they have been started living separately. I(Son) am living with my mother and my younger sister living with y-father. The mistake my mother did was, she started using x-husband's name in my educational proofs. All my educational certificates must have been used x-husband name, and my younger sister has y-father details in all her proofs. i knew its a fault. What i am asking is, my passport contains x-father name and my younger sister personal details has y-father's name. If suppose she applies for passport if she puts y-father name, when she want to come for abroad as a visitor to visit me, then will be there any problems???
