Thank you Randy. Unfortunately she does not have any record of her birth (either in China or in HK). She was born in 1929 or 89 years ago in China! Record keeping was non existence especially for females in old days. We do however got the Certificate of Registered of Particulars from the HK Govt which shows records of detail documents registered including her fist HK ID card issued in 1951, subsequent HK ID cards, etc.... We uploaded this certificate of registered particulars to the NVC website under the applicant birth certificate field in hope of NVC accepting it. Unfortunately, they rejected the document I guess I would like to know if it is necessary for her to go to 广州公证处 in person to get the notarial certificate of birth? She has mobility problem and it is difficult for her to make that trip.... Thank you
