I actually agree on your post Mike, I think the main reason why we apply to have another Passport is to make our life easier to travel.
I am entitled to have an Italian passport but I have never been bothered to do it. I only realised the difficulties when I got married with my husband and I needed to apply for a visa and you know the rest.
I will apply for British Citizenship when the time comes for me, but for purely convenience reasons. I will retain my Philippine passport as I am a Filipino and nothing in this world can change that...
