The Immigration European Economic Area or EEA Regulations for short constitute the law that implements the right of free movement of EEA Nationals and their family members in the United Kingdom. It is based on Directive 2004/38/EC and it allows EEA citizens and their family members to live and work in the UK without explicit permission. Although Swiss citizens are covered by a separate bilateral agreement they are also treated basically the same as EEA nationals. Non- EU Family members need a special entry clearance known as the EEA Family Permit to enter the UK. The basis of the Immigration EEA Regulations 2006 is Directive 2004/38/EC. Member states are bound by the EC Treaties to implement Directives into the National Law.
