Thanks all for your comments...
Btw I want to clarify few things about my question. I am EU citizen so i have no restriction to work in UK.
I am a PhD student (funded) in the USA, but I am academically not satisfied, so I have now an offer from a UK University, which I love, but which gives me no money
I can partially agree with you (Ghost). This is what I have noticed. There is a big difference if we are talking about USA or UK.
In USA it is the norm I would say to get funds from the school for a PhD, in the UK it is the opposite. I am a PhD student in the USA and I am funded, I would not do a PhD here without funding (for many reasons...) and would not advice anyone to do one. I never met any PhD student in the USA who was not financially supported by their school, therefore I agree with you (if we talk about USA).
For UK it's a different story. TAship and GAship and such are widely available in the USA, they are very less common in the UK. As a graduate student
in the USA I have always had one. While I did not find any TAship advertised in the school I want to go in UK.
The school I want to attend in UK is SOAS (for those who were wondering about how prestigious is the school...), and so far I do not know about funding but current students told me that chances to get one are close to zero (I think they only give one for each department or something).
Corinna, thank you for your comments...
