“A clause in the Crime and Courts Bill, published today, will remove the full right of appeal for those applying to enter the UK as a family visitor. Subject to Parliamentary approval and Royal Assent, this change is expected to come into force by 2014. Refused applicants will still be able to appeal on limited grounds of human rights or race discrimination.”
