you are misinterpreting this link. The link is about 'refugees' both legal and illegal, but you stated in your post 'immigration'. Not the same thing at all. The Windrush immigrants were not refugees any more than sub continent immigrants were refugees. You play into the media idiocy by conflating the numbers and the people involved.

I think that you will find that is incorrect. Following the Eastern European Pograms in late 1890s and early 1900s (which saw my paternal Grandparents arrive in the UK from Lithuania) saw a substantial influx from those countries. There was also the 'Windrush' Caribbean immigrants in the 1950, from former British Colonies. Not forgetting the large numbers of immigration from the India Sub Continent from 1960 to the mid 1990s and supplemented in 1972 by the Asian peoples thrown out of Amin's Uganda. The numbers right now, of illegal immigration, as opposed to legal immigration, is a relatively small number. Its just that the media want to make a meal out of it and the government is powerless to stop it, rather than the actual numbers involved.

Use an agent and do your extension done before you leave in September. Friend of mine has done just that last week, got his extension through an agent 3 months early due to his travel plans .
