Im coming back to the Phils in late Sep to stay for six months plus and get married in Jan/Feb we would then Ideally like to apply for a spouse visa for arrival UK in Sep 2010 this is because im away a lot with my work in summer and so not a good time for arrival earlier

My questions are my C. of N.I. exchanged in Manila is good for how long? or can I get it whilst im here nearer the wedding time?

Is it possible to apply for the spouse visa to start from Sep even if the application is in say March(as I will be able to fill it in whilst im here with Jhean)? If not what are the implications for the next UK visa?
