8老師您好，
My mom was born in 1970 in Beijing and moved to Hong Kong in 1976. Then, She moved to Canada in the 90s became Canadian. Now I am applying green card for her…She doesn’t have a birth certificate from China and doesn’t have a 戶口. She does have a Statutory Declaration from Hong Kong government where my deceased grandmother declared that mom’s birth date, and birthplace in Peking, China. (see attached). If I provide this declaration, is it sufficient for mom’s birth certificate ? 太感激您！
-This document is good, but probably it is not enough. Another affidavit like this one is needed, so you had better ask one of your close relatives who knows your mother' birth well such as your uncle, aunt or any one of the other close relatives to write a affidavit to recall your mother's birth date. The affidavit should include your mother's parents' names, place of birth of your mother and the date of your mother birth. The affiant should indicate his/her relationship with your mother.Then, notarize the relative's signature on the affidavit.
Thus, I think it should be enough to provide the Statutory Declaration and the affidavit for your mother's immigration.
