British people - Thinking about emigrating...

[Dystopia]

I'm not in London but if you speak English most people in the UK won't care where you come from. (Although as with every country we have a few bastards too).

London has a Little Portugal

There are estimated to be some 27,000 Portuguese in this part of London, which makes it one of the largest communities within the 500,000 strong Portuguese British population

I hated learning French too. I spent 5 years of high school learning it but now I remember just a few words, a massive waste of time.

The rule is that speakers of Latin derived languages have trouble learning other latin derived languages if they learn English first - That was my case, I had a problem with pronouncing French words with an English accent and trying to replace words with English ones - Best example is "Je n' speak French"

I'm not so sure about your first rule - I mean, in Portugal we say we accept all immigrants as well and that's the perception people have of our own society, but the truth is that if you're a black immigrant you'll be massively discriminated and the same applies if you're gypsy - In fact, people will never see you as a Portuguese, just as an immigrant, even if you've been living here for 500 years.
