Immigration is an issue that features regularly in the Brexit argument, with considerations ranging from healthcare to security. Here are some of the main points made by each side on the issue:
What the Remain campaigners are arguing
1. Leaving the EU will not stop immigration to the UK, and it could potentially be made worse by border controls shifting from France to Dover.
2. Leaving the union would mean that UK citizens would lose access to free emergency healthcare in Europe.

3. EU membership means UK police can use law enforcement intelligence from 27 EU countries, and will have access to fingerprint and DNA information.
4. New EU migrants will not have full access to certain benefits until they have worked here for up to four years.
What the Leave campaigners are arguing
1. Being in the EU results in large numbers of people from across Europe entering the UK, and stops us controlling who comes into the country, on what terms, and who can be removed.
2. Immigrants from the EU put more pressure on an already strained NHS and potentially worsen the A&E crisis.

3. Voting to remain would mean losing more control of our borders to the EU and European Court.
4. The pressure that large inward-migration from the EU puts on schools and hospitals means the UK is forced to block people from non-European countries who could contribute to the country from entering.
