I guess you are saying is about the marriage license,that u need to wait for 10 days,before u get married,how ever it is depend on our local civil reg. cause if you're fiancee have connection from any staff at her LCR,you can get married after completing requirements,and then they will issue the license after 10 days ( that was in Rizal,Angono)

About CNI you are mentioning you can have it back at the same day from British embassy
