Dear Brother ,
Greetings ,
Its easy to get a birth certificate .
You need to have these documents : 1. HighSchool Certificate
2. Copy of Passport
3. Medical Certificate ( Issued at the time of birth )
You need to proceed to NAGAR PALLIKA of your city and get a certificate issued by attaching these documents with the application form . They will make the certificate with the present date and not past date. And its acceptable .
BEST OF LUCK
