Two years after accession, in May 2006, Ireland will have to decide whether it then wishes to apply the full body of rules on freedom of movement, or the acquis. The expectation is that most member states would apply the full acquis at this stage. However, member states may opt to continue the national measures operated in the first two years if they wish to do so and it is expected that this will only happen where granting full freedom of movement may pose a threat to their labour market.
