I agree on the do's and dont's side of things
Also without going overboard peoples basic rights.
that Women and Men have the vote aged over 18.
As i remeber there were issues in some areas where postal votes were "borrowed".
I do think we forget some of the people i speak to from various parts of the world. Many are very well educated and have great intelligence and common sense. Others are not so blessed with a great education and could easily once here not learn english and realise what is and isn't allowed here.
I know in many communities where Wifes come from abroad they are not aware of very basic rights we take for granted and if they do need help say with regards domestic abuse or just simply the right to work. How would they find out this infomation if they cant communicate in English.
But the testing of English i feel should be done before coming to the UK as many other countries do.
