催了一圈，却收到RFE.
from TSC requesting for evidence:
Please submit a photocopy of your official birth certificate. If the document is not in English, please include a certified English translation. If a birth certificates does not exist or cannot be obtained, you must demonstrate this and submit secondary evidence pertinent to the facts at issue.
是一定要出生公证原件吗？还需要其他的文件？
有知情的大侠，请不吝指教,非常感谢。
