我是七十后，不记得有出生证明。我在国内很久以前办过一个公证，
证明我妈是我妈，-What is that?
Birth certificate should include the peron's name, the person's parents' names, the person's place of birth, and the peron's date of brith.
能用嘛？还是去验DNA快一点儿？我妈如今人在美国。
-叫国内当地派出所出个证明，然后去公证处作个公证。
You may do DNA test to prove your blood relationship with your mother, but your mother needs to have her bith certificate for her I-485 filing.
