I was wondering when the original notarial certificate of birth (instead of a photocopy) is needed again once the VISA is approved, and if so, about how many are needed. I am in California and I have been checking online on different situation where it might be needed, but there seems to be none. What are some situations where it is needed again? Some situations I checked that I don't think the notarial certificate of birth is needed: Marriage Certificate, ID Card, SSN, Permanent Status, Driver's License, Passport. Thanks in advance.
