Thank you so much 8老师! - More Questions

1. I can ask my aunt for the birth affidavit and noterized. However, if my aunt not 100% can read english affidavit. Do I need to prepare both english and chinese( translated from english) for her to sign? Or, english affidavit is good enough and we can just explain to her if she doesn't get some meaning of it.

2.  Do I need to get a proof for mom that the 'primary document is unavailible", see section B #1: https://www.uscis.gov/policy-manual/volume-7-part-a-chapter-4#footnote-13 

Thank you so much!
