I live in the Netherlands but I specifically took a vacation in the UK to do my IMC. Even though I can't legally use it in NL, and even though it's probably going to be a challenge to revalidate it as well. (I still have a few months to sort that out though.)
I mostly did it to enhance my flying skills, and to have a "way out" in case of deteriorating weather. I'd rather fly illegally and live, than legally become a CFIT or LOC-in-IMC statistic. And it was great fun to do anyway.
