One of the key slogan for the exit campaigners has been to take control of the borders and key issue has been immigration. According to Prime Minister David Cameron, who is about to resign tomorrow the referendum to stay was lost to immigration fear. While the upcoming female Prime Minister Theresa May has vowed to deal with immigration in toughest possible way the issue is more complex than just calling for border controls.

Let’s take a look at the key issues that will need answering if the UK finally chooses to leave the bloc.

• More than 3 million workers from the European Union work in Britain and the new prime Minister will have to choose how to approach to them. Many of them have stayed more than five years in the UK, hence qualify for permanent residency. As of latest political commentaries these people are more likely to be allowed to stay in the UK.
   
• More uncertain are the futures of the people who has stayed short in the UK, less than a year or moved in after the referendum. There is a strong possibility that they could be send back or apply for stricter work permit. Cost of living could go up if the EU low-skilled workers, who would not meet the visa requirements upon exit are asked to leave.
   
• Similarly on the EU side, the skilled workers from the European Union will face uncertainties. While the EU could be considerate towards those already staying or working in the EU but any future aspirants will have to secure an EU-wide work permit. Last month, Spanish Prime Minister Mariano Rajoy warned that after Brexit, Britons will lose the right to freely move, work and do business in world’s largest economic area.
