Here is how to do it under 10 days. But everyone, including the officials, must be on the same page to pull this off.
1. So have your fiancée check with local registrar to see if this will work for you. Most times you could file for the license in advance and complete other requirements when you arrive. You need to check with the registrar and see if they will do this.
2. Then you go to the Filipino Embassy near you with a filled out marriage license (just your half) and asked them to certify the document. They should do this and usually will cost about $25 and a return visit the next day to pick up the form.
3. Once you have the document and then send it to your fiancée. Next have her fill out her part and take it to her local registrar for filing. Do this about three weeks before your arrival to help in meeting the 10 day requirement. She also has to give the registrar her CEMAR.
4. Upon arrival go to the US embassy (you must make an appointment), and get a legal capacity to marry. Cost $50 fee.
5. Now take your legal capacity to marry and a copy of passport entry to the registrar. They may give a release date of the next day for marriage license. However you need to attend the family planning seminar. 6. Returned after the seminar, and get the license. Now go and get married and have a happy life together.
This has been done before but your actual mileage may vary. Good luck.
