I think Sushee means that he is looking for share accommodation, so rent shouldn't be that expensive?

Sush, I think telling him to have a decent plan and some savings before he comes over is a good idea. He's an adult now and even though you're still his Mum, he has to do this himself and you know that, but he has to learn it too. I totally understand your worry about him getting there and thinking you'll support him again. Maybe ask him to sign up for recruitment agencies etc and make an active efffort to find work or training to do once he's here, because if he leaves it till he is actually there, then there are going to be a few weeks at least before he can get that sorted out and in the mean time he'll be doing nothing kwim?
