Can I submit a laminated birth certificate with my US passport?
If it wasnt laminated by the issuing agency, I wouldnt bother. I assume that US policy would be the same as Canadian policy in this regard. An unofficially laminated document cannot be properly checked for alterations or to ensure that it is genuine. It would be rejected out of hand. It is never a good idea to laminate a document that you may need to present as an official, verifiable proof. In this situation you should apply for a replacement birth certificate, as youre likely to have to pay a second application fee once the original is rejected due to presenting an altered official document. Your second application may be delayed due to additional scrutiny.
