"2006 saw changes that will affect many immigrants in the UK. Those on a work permit or on HSMP or an ancestry visa in the UK will have to wait longer and have to meet more stringent criteria to gain permanent residence. From 2 April 2007 all those applying for permanent residence will also need to pass the Life in the UK test."
