Are you close to an office that does emergency passports? A friend of mine had to get one done because his travel agent did not tell him that he needed to make sure his did not expire within 6 moths of travel to St. Lucia and he was able to get one within hours. If she completed everything in her name change process it should be fairly easy to do. If she didn't officially change her name with Social Security, etc. it may not work out. Anyway, hoping things work out for you. No matter what as long as it is you and your fiance and you end up married all is well. (That is what I have had to tell myself because people who were supposed to be there now have excuses!)
