Selfish and Self-righteous

Of the 185,000 foreigners who were issued with Student Visas 5 years ago 21% are still in the UK, according to research undertaken by the Home Office.(BBC Radio 4"Today".) Two-fifths of those who were issued with Work Visas, which normally have a time limit, are still in the UK.
The native British have only themselves to blame.
Enabling foreigners to extend their residence here (even permanently) is big business. They even work on behalf of those who are here illegally. (See e.g. www.ukvisaexperts.co.uk, which advertises on this very blogsite!) If there is no law against them doing that, then that is remiss of the Government.
By employing notional issues framed by the moral-sounding phrase "human rights" those in the immigration industry are both selfish and self-righteous.
