Millions of livelihood are at stake here if the European Union and the United Kingdom fails to resolve the issues of migrants, who are already working in both the regions. Around 3 million EU nationals are currently residing and working in the United Kingdom, who make up almost 7 percent of the total workforce. Similarly millions of UK nationals are working in the European Union.

There is a profound uncertainty over what will happen to these immigrants. While the EU and the Britain can take some time to decide on their future immigration policies, they need move fast in securing the future of these workers or else their jobs would be in jeopardy and in the longer run would affect the economic wellbeing. Almost 71 percent of the EU nationals in the United Kingdom have stayed in the country for more than five years, so are eligible for permanent residency; however, the referendum has pushed that into the realm of the uncertainty.

Another big uncertainty is surrounding the low skilled workers. If the UK adopts an Australian style point based immigration system, many of the low skilled workers currently working in Britain would not be eligible for a working Visa, which could result in deportation and a massive sudden skill shortages.

Britain needs to take the first step among the two regions and secure the future of the foreign nationals currently working if not be prepared for a backlash for all the Britons working in the EU.
