The United Kingdom Government has stated that rules allowing EU citizens to live and work freely in the UK will end in the event of Brexit without a deal on October 31
Therese is considering expanding her freedom of movement by 2021 or allowing EU citizens to stay for three months before applying for a longer stay.
These opportunities have already been dropped in favor of a new approach, to be determined later.
Boris Johnson said the United Kingdom would not become "hostile to immigration".
The Prime Minister added that "immigration in the United Kingdom will be controlled democratically".
However, the group of three million campaigning for the rights of EU citizens living in the United Kingdom stated: "Ending freedom of movement without introducing legal provisions for those EU citizens who have not yet applied successfully through the settlement scheme will mean that millions of legal citizens will be removed from their legal status overnight. "
Freedom of movement allows EU citizens to live and work in other European Union countries.
In a statement, the Home Office said:" EU citizens and their families still have at least 20 December 20 to apply for
"Freedom of movement, as it currently stands, will end on 31 October when the UK leaves the EU and after the Brexit government will introduce a new, fairer immigration one. a system that prioritizes skills and what people can contribute to the UK, not where they come from. "
A Downing Street spokesman added that" stricter rules on crime "would be introduced for those coming to the UK.  According to the withdrawal agreement negotiated by former Prime Minister Ms May with the EU, freedom of movement would remain for a transitional period of two years.
However, MEPs repeatedly voted in favor of Ms May's deal and unless an agreement can be reached with the UK will leave without a deal on 31 October.
Mr Johnson said he wanted to reach a new agreement with the EU but was ready to leave without a deal if an agreement could not be reached.
Who will be affected?
In a bargain scenario, those EU citizens with permanent residence in the United Kingdom – granted after living in the UK for five years – should not see their rights affected.
EU nationals already in the UK can apply for established or pre-established status in the same way as they do now.
Ending freedom of movement would not affect EU citizens coming for breaks and short breaks. but would affect those wishing to work or study in the UK.
Changes in freedom of movement will not directly affect Irish citizens. In May, British and Irish ministers signed an agreement to guarantee the free movement of their citizens crossing the Irish border and cross-border access to research and health care.
What is the reaction?
Conservative MP Alberto Costa, campaigning on the issue, described the government's announcement as a "deeply concerned move" and criticized "a total lack of clarity"
. He also warned that: "What we do with EU citizens after Brexit, will be reflected by EU countries to UK citizens in the EU.
"If the British government abruptly terminates legal arrangements for citizens, it will have a direct negative impact on innocent British citizens working in the EU."
Lib Dem spokesman Ed Davy accused the government of being " irresponsible and reckless. "
He said that "employers up and down the country will not know what the law is," adding that "this will significantly cause damage to duty-free Brexit."  The director of the Migration Observatory, Madeleine Sumpions, said that ending the freedom of movement could "simply mean ending the role of EU law to govern the rights of EU citizens here and replacing it with UK law."
However, she said it could also mean the introduction of a new "substantially more restrictive" system.
She said it would be "quite difficult" to implement any new rules before the registration process for those EU citizens who have been living in the UK for years is completed.
Can the government drop the freedom of movement?
Apparently, free movement policy will automatically be transposed into EU law on the day of exit, as provided for in the Withdrawal Act.
Ministers may amend some regulations through a regulation – a form of secondary legislation – but only to address "deficiencies".
Therefore, the government had to introduce an immigration bill whose first clause ended freedom of movement.
But this has been delayed – partly to avoid its use by rebels to take control of parliament – and is unlikely to be passed before the day of exit.
BBC Home Affairs correspondent Danny Shaw says the logistics of the new scheme are still
"You have to remember this: 40 million people arrive from the EU, EU citizens, every year in the UK. airports, which will signify enhanced controls if the freedom of movement is abolished immediately and this will put a heavy burden on staff working in UK ports and airports. "
