subject : immigrating to the Netherlands.
I have a British passport and am living (co-habiting) in England with
my girlfriend who is here on a south african student visa. We would
both like to go work in Amsterdam.
She has been studying/working in the UK for 3 years, I have been
working here 6 years and we're been living together for almost a year.

I've heard of "samenwonen" and "relatieverklaring" but can't find many
English references.

Can we both live/work in the Netherlands? Where could I find out more?

thanks!
