I might add. I think it might be difficult to get the papers AND get married in the same 18 day period. There is a waiting period after getting marriage license. Please investigate all this first. I had to make 2 trips. I arrived on May 4 got my "legal capacity to marry" from embassy that morning, on the plane to Davao in afternoon. Engagement party that evening, lots of pictures. Applied for license in the morning May 5, little running around to satisfy requirements. My wife over 25 so they say no need for the seminar. But only then could we book the wedding with local mayor, not easy to do. And we had to wait 14 days to pick up the marriage license (mandatory waiting period). I had to go home and make 2nd trip couple weeks later to marry on the May 20. Then honeymoon after of course. Make sure you plan everything in advance to make sure you can get it done in 18 days WOW and gl. Don't forget lots of photos of both of you together. Engagement, wedding, honeymoon, family etc.
