I applied for immigration with my hubby as the sponsor. We both live in the US, but I was born in China. I mailed in my app which included a copy and translation of my Chinese birth certificate which was signed by the translator and notarized. Now I just got a letter from CIC saying that I am missing or have incomplete documentation for birth certificate. The 2nd page is asking that I must attach "certified copy of the original document" and "certified translation of the document." I'm not sure what else needs to be done??? Do I have to go to China to get a certified copy? I am the principal applicant and we have no children or other dependents.
