I have contacted the British Embassy in Manila to ask... Told them I have an appointment with them on 8th May to exchange my CNI which I am due to get from UK on Tuesday. Asked them if I need to get the CNI or just fill out the new form and turn up with that?
In the meantime I shall go ahead with my appointment unless I hear different..... The CNI is probably the most important document I need to get married, so not going to not get it unless it is official.... I may still get it as it is only £35 and I can afford to lose that rather than a lot more should I not get it and it is indeed required.
