This has to be the craziest idea EVER!! I have 2 daughters of 18 and 20 - I would worry about them living alone in any country even at their ages!!

I would recommend Spain too, closer to home, more lifestyle choice, not needing sponsorship and if you do your research, the chance to live with a Spanish family while learning the culture and language. If this interests you, send me a message as I know of a British teacher of Spanish who was looking for young people to do exactly this.

All I can recommend is gain some life experience before contemplating putting yourself in a miserable position.

Good luck!
