Well ... I've HEARD of red ribbons/seals &c. But, to be honest, I've never really been entirely sure of their significance. And, since you already HAVE your fiancee visa, NSO-authenticated birth certificate and CENOMAR in any case, the best plan would be to take all your documents WITH you when you GO there ... if only to keep your mind at rest and avoid any likelihood of hassle!

Good Luck, and
