When Brexit goes live, citizens of the European Union can no longer live and work in the U.K. without a visa.
U.K. Prime Minister Theresa May's official spokesperson said Monday free movement of people from the EU will end once Britain leaves the bloc in March 2019.
That spokesperson also said it would be "wrong to speculate" about what the immigration system in the U.K. will look like post-Brexit.
The confirmation came after several cabinet ministers made some conflicting statements on the subject.
But International Trade Secretary Liam Fox told The Sunday Times the cabinet hadn't reached a decision yet.
According to the latest data, more than 3 million EU nationals live in the U.K.
