Think first
Please people think carefully before rushing into woking for these outfits in the UK.
Like others have said it is very hard work for little return and cost of living ie accomodation is very expensive.
Dont think the experience will get you a foot in the door back home.
Many dont really give a toss if you have experience... this I have gathered over the years.
Sorry dont mean to be negative, just want to say think about it carefully first.
