...I'm going to apply British Citizenship by June 2013 but I can't wait for that I need holiday....
It will take some time to secure approval of the application. Next step is to attend the Citizenship Ceremony.
Following that you would need to apply for British passport, then attend the passport interview.
Everything takes time and money these days
With luck on your side you could expect that holiday August/September

Good luck.

PS Even applications for a Schenghen visa can take time and cause stresses. Thank you Terpe I really appreciate all the help in this forum and hopefully I can get british passport before November so we can book our flight early back to PI... Can't wait..
