My Fiancee in the Philippines needs an annulment can I marry her/him?

Philippines does not allow divorce as it is not legal way to dissolve a marriage according to Philippines law? One must undergo an annulment according to the Roman Catholic beliefs which has been known to be very time consuming, costly and often time unpredictable as to when or even if the annulment will ever be finalized? Most annulment process can take between 1 to 2 years and sometimes never get finalized by court rulings. Without any annulment paper work the U.S. Citizen sponsor will not be able to file a petition for alien fiancee?
