How to handle the birth notarization of immigrants to the United States?

I worked in an investment immigration company before. Please refer to the following process:

The local police station should prepare a birth certificate;

Take out the birth certificate and go to the local notary office to prove that the translated version of the birth certificate is consistent with the original Chinese version, and both Chinese and English versions should be notarized.

If it is useful, please adopt it. thank you
