I have just joined the forum as I'm looking for info for a friend who's fiance has just arrived here in the UK. We were wondering if it is allowed to take unpaid voluntary work while under the restrictions of a fiance visa. I did a search here and found this posted by Darren-b:
The guidance for visitors on the ukvisa's website says
You cannot:
take paid or unpaid work
produce goods or provide services in the UK, or
sell goods and services to members of the public.
I can't find it on the ukvisa website but it does answer my question.
CHEERS!
