Unless you were divorced from each other between the marriages, you won't be able to provide documentation of termination of all previous marriages prior to your current marriage........which is required. Without documentation that the first marriage was terminated, USCIS would not recognize the ceremony in PI as a marriage.

□ Proof of termination of all prior marriages of your spouse (divorce decree(s), annulment(s), or death certificate(s));
□ Proof that all earlier marriages ended (divorce decree(s), annulment(s), or death certificates(s)).
I would not list the ceremony in PI as a marriage. I would consider it as a celebration or re-commitment...but not a marriage.
