As highlighted by the Red Cross, the Home Office has introduced a new and improved refugee family reunion policy. The big change seems to be to the treatment of adult children of refugees who have managed to reach the UK. They are still to be refused under the Immigration Rules, which only permit the entry of children under the age of 18, but the policy goes on to state:
The caseworker must go on in every case to consider whether there are exceptional or compassionate circumstances, including the best interests of other children in the family, which warrant a grant of leave to enter or remain outside the Immigration Rules on Article 8 grounds. These could be that the applicant would be left in a conflict zone or dangerous situation and become destitute on their own; have no other relatives that they could live with or turn to for support in their country; are not leading an independent life and the rest of the family intend to travel to the UK.
There will be few who benefit from the new policy but there will be some.
