Putting this as emergency help because I'm currently dealing with homelessness alongside physical and mental disabilities in my home country (the US).

My fiancé lives in the UK and does have her own flat and a decent paying job, but the first visa to get married is £2k roughly, and six months later, it's another £5k. Every little bit helps, because once we get the initial fiancé visa, I'll be able to stay in the UK with her, and we'll be able to get the rest put together.
