British citizenship when to apply

[LadyJ]

Hi folks

my wife got her residence visa in january this year so when can she apply for british citizenship and how long does it take and cost ?
also my wife gave birth while here in uk and gave me a wonderfull son who now has a british passport but we was reading on the filipino embassy site in london they also class my son as filipino as his mother was filipino so does this mean hes entitled to a filipino passport also ?

thanks

WHat you read on Philippine Embassy website was obviously correct. Report your sons birth on the Phil EMb before he turns 1 year old If not you will pay a late registration fee, i think £18.
