Many in the Remain camp believes immigration benefits the economy, and the UK outside of the EU will be required to accept free movement of people as a part of any deal in order to gain access to the single market.

They argue that the Prime Minister secured a deal that would prevent new EU migrants from claiming in-work benefit for the first four years in the UK. The deal negotiated would allow the UK to impose an “emergency brake” on in-work benefits for EU migrants for their first four years when there is an exceptional level of migration to the UK.

They claim that EU migrants pay more taxes than they take out.

They believe EU migration accounts for just half of all migration to the UK.

The Leave camp argues that it is impossible for the UK to control migration – a total net of which is over 300,000 a year – if we continue to be a member of the EU. Net migration is the difference between the number of people moving to the UK for more than one year and the number of people leaving the UK for more than one year.

They argue that this lack of control equates to a lack of control over the economy and domestic issues such as housing, as well as welfare payments to people who are not from Britain.

They believe the sheer volume of migrants to the UK has put a strain on public services.

They argue that the Government has failed to meet its target to cut immigration to under 100,000 a year and that free movement of labour within the EU has gone too far.

They claim official figures do not fully reflect the true scale of migration, especially following the recent additions of new countries such as Romania to the EU.

Leaving the EU would mean the UK no longer has to apply EU law that allows all EU citizens to easily move to between member states (individual EU countries). It could be therefore argued that the UK would gain control over its border by applying immigration rules to any non-British citizen living in the UK and those looking to live in the country.

The Remain camp has, however, highlighted the potential impact this could have on the economy. A significant number of EU workers would fail to meet the high entrance requirements from the British government – which are to have a graduate-level role and have a salary that is more than £20,800 – a figure that will increase to £30,000 from April 2017. This could hurt businesses, particularly those who seek to be relatively low-skilled staff, such as waiters, and so have an impact on the wider British economy. The UK, if it votes to leave, would also need to negotiate a deal with the EU to trade with it. It is likely that the EU would, as part of this deal, insist on some form of free movement of people before any agreement can be reached.

 Finally, it is also worth noting that immigration works both ways and remaining EU members may wish to place restrictions on UK citizens studying, working or retiring in their country.
