To update you all on my situation. Although our deadline for visa extension is only 27 May, it is not a problem.
Before I tell you what happened I just want to say that I thoroughly checked out Philippine Embassy website, Home Office Website and phoned both up to get as much info and advice as possible. I found Fil embassy very helpful but Home Office (although they try to be helpful) not helpful because they have to keep to guidelines on what they are allowed to say. Therefore because I cannot find answers to all my questions from those two sources I asked this website for answers based on others who have faced my situation. This website has been very helpful to piece everything together in my mind!. I now know what to do! Back to my story.......
We went to Fil Embassy yesterday to give notification of marriage and passport amendment. They saw us straight away without an appointment. As we had already filled out all our forms and photocopied everything they wanted we were in and out in less than 30 mins (including waiting time). We were told we could collect the amended passport today, but as we are now on honeymoon, will collect next wednesday. We have appointment with Home Office in Croydon 2 days later on friday.
