In theroy thats what the finacee visa is about ie come over to the uk and have six months to get married. But in this time she would not be able to work untill married and her visa changed to flr status.
Basically a young un married fillipina with out money and propety will find it hard to get a vistor visa to the UK.
Also its very tough even for experienced highly qualified phills to obtain a work visa in the UK.
as a job advertised in the UK must first be offered ro british nationals, eu based persons and then people from the rest of the world.
Please dont think we are being hard on you both we are just passing on the infomation we have all gleaned from our own experiences.
