The free movement of workers between the European Union and United Kingdom will end when Britain withdraws from the union, according to British ministers.
"Free movement of labor ends when we leave the European Union in spring 2019," immigration minister Brandon Lewis said on Thursday.
The minister also said a new immigration system would be in place by April 2019, when the UK is scheduled to leave the EU.
"Once we have left the EU, this government will apply its own immigration rules and requirements that will meet the needs of UK businesses, but also of wider society," Interior Minister Amber Rudd said.
"I also want to reassure businesses and EU nationals that we will ensure there is no 'cliff edge' once we leave the bloc," she added.
A new research shows more than one million foreign workers are planning to leave Britain as London is negotiating Brexit, amid fears the country is facing a Brexit brain drain.
According to the survey conducted by a global accountancy giant, Deloitte, about 36 percent of foreign workers in Britain say they are preparing to leave the country by 2022, with 26 percent planning to move out by 2020.
These figures show that 1.2 million non-British workers out of 3.4 million in the country are likely to leave the country which is expected to create a severe jobs crisis in the country.
Highly skilled workers from European countries are the most likely to leave the UK, with 47 percent thinking about departing in the next five years.
