Is birth certificate a must After 1970?

[kp9999]

Hi
My HR told me that INS made it strict on birth certificate procedures.
After April 2007 Birth Certificate is necessary for people who born after 1970.

Even if a person can provide a Non Availablity certificate(who born after 1970), it still mandatory to get it regisetered in local municipal office and send the Birth certificate to INS..

Is this true??

I am born after 1976 and no Birth Certificate for me..I am planning to send my School certificate along with one affidavit and one Non availablity certificate though..

Should this be OK?

I appreciate your help

thanks
