why the rush to go to the philipines?

let her buy a house there and live off the rent from yours back in the uk

the only reason for her to get a uk passport which will take 3 years, if you do get ill and need to come back to the uk she can come with you, without the need to get a visa also you will know if your clear from cancer..the cost of cancer care in the philipines wont be cheap and maybe far more expensive than you think.
