我已经为爸妈递交I130。移民局要求提供出生证明或其它文件证明我和父母的关系。我的出生证明是2002年公证的。可移民局认为是一个延期的注册。如何办理移民局认可的出生证明？恳求各位高人指点。下面是I797内容：
I-797E, Request for evidence.
Upon review of the petition and supporting documentation, it has been determined that additional evidence regarding the birth of xxxxxx(me) be submitted. The petitioner has submitted a birth certificate that has a delayed registration of approximately 35 years. As such, the petitioner is required to submit the secondary evidence to establish the claimed biological relationship.
