I htink a few other countries require the applicant speaks the countries official language. My Wife met ones applying for auz and canada and had to get a certain level during her ielts exam.
I think i read on aswasa(us phill website) when it was about that holland was bringing in the same.
Sadly i can't see the EU court on the countries court saying it is unfair, as they will say its for the benefit of the applicant in everyday life.
I think many on here although would find it a pain if the UK brought it in would admit that they would like to see that everyone who entered the country spoke English. As its not unknown in my area of London for some people to have so poor english they can't communicate with English speakers even in basic situations.
What Level of german do they expect uli is it very high level or just basic conversational german? Just intrested as i would expect it to be brought in the UK very shortly.
Hopefully your Wife to be is soon with you.
