The property developer, whose report was based on National Insurance Number registrations by EU workers in recent years, called on the Prime Minister to act immediately while speaking to radio host Julia Hartley-Brewer on talkRADIO.
Mr Tice is a close friend of Nigel Farage and Arron Banks who, along with Andy Wigmore, formed the self-proclaimed ‘Bad Boys of Brexit’.
He said: “It’s a function of the success of our economy, the ability of people to get jobs in the UK relative to the regrettable difficulty of finding jobs elsewhere in the EU.
“Clearly, lots of EU nationals have come to work in the UK under the existing rules – that’s fine – but after the Prime Minister’s good speech last week, she needs to follow it up and actually start to clarify when the freedom of movement rules are going to change.
Mr Tice warned of a surge of EU citizens seeking jobs in the UK following Mrs May’s speech, which confirmed the UK would seek to leave the single market and regain control of its borders.
“If you can’t get a job elsewhere in the EU, you’re going to say ‘well this is my last chance to get into the UK’ so more and more people are likely to come to the UK because they can get jobs here,” he said.
“The Prime Minister needs to clarify the timing. Our recommendation is that she should say ‘actually the freedom of movement rules will change with effect from now’.”
The campaigner called it a “rational discussion” that needed to be considered by the Government.
He said: “The Government should take the moral high ground and say that people who have come here under the rules will be able to stay, but we need clarity.
“It’s a sensible, rational discussion, and people need to know.”
The call comes as latest Office for National Statistics figures showed net migration – the number of people coming to the UK minus those leaving – was a near-record 335,000 in the year to June 2016 including 189,000 EU citizens.
