I have a birth cirtificate which I got from the proper authority in India. But the cirtificate does not show the mother's name. Is this cirtificate sufficient for interview at chennai? Or do I have to make an affidavit?. If I have to get an affidavit, what should I have in there for a missing mother's name or that I do not have a birth cirtificate?. Any help is appreciated. Thanks in advance - Ram
