Freya there is persecution based on religion and sexual orientation in those countries.
However, personally, I have no issue with people applying to live here on economic grounds i.e. in search of a better life. If, once here, they work and contribute to society, what’s wrong with that - no matter where they come from.
I realise my view is at odds with several posters on this thread but, IMO, we (led by the government) should stop viewing immigration as a problem to be solved and start viewing immigrants as an asset to our wonderfully diverse, multi racial country.
