I just had my husband's family visit visa approved. When I went to MOI, they didnt asked that my marriage cert be stamped by the Phil. Embassy. Basta makita lng nila na nka-red ribbon OK na. You will submit photocopy of your RP, your passport & your husband, and marriage cert. The originals that you must submit are NOC to Sponsor & Salary Certificate.

I hope I answered your question.
