Here is the problem. I have a long-term visa (I live and work in Germany and I'm married). I want to visit London (to be specific, I am from Tunisia).
I heard that having a long-term visa for a European country can make it easier for me to apply for a UK visa (as I saw, the visa is required in my case).
I don't know how I should apply for this visa, and to use my European visa to facilitate the steps.
long term visa for an european country, can make it easier for me
Not always. Google forapply for uk visa
and the 1st link in the result list is where you apply. – DumbCoder Nov 6 '17 at 9:42
