Asylum seekers who commit crimes or work illegally are to be thrown out of taxpayer-funded accommodation and lose their hand-outs.
The rule changes, first announced last November, mean only those with legitimate asylum claims who follow the rules will get support, Home Secretary Shabana Mahmood will say on Thursday.
The measures, coming into force in June, will remove support payments and accommodation to asylum seekers who work illegally or have been granted the right to work, or who have the ability to support themselves.
Hand-outs such as free hotel rooms will also be stripped from any migrants who break the law.
The current statutory legal duty to provide asylum seekers with support and accommodation – first introduced in 2005, reflecting a European Union directive – will be replaced with a ‘conditional’ system.
It came as 204 migrants reached Britain on Tuesday by small boat across the Channel followed by more arrivals on Wednesday, thought to number several hundred.
Separately Ms Mahmood will confirm that migrants who wish to settle here permanently must show they can speak English to a higher standard.
Current English tests at GCSE equivalent will be raised to an A-level equivalent for those applying for settlement in Britain.
The higher requirement was first announced by ministers last May and will come into force in March next year.

Home Secretary Shabana Mahmood is set to take a swipe at Green Party leader Zack Polanski’s ‘fairy tale’ migration policies
It could also be rolled out to other types of migrants at a later date.
In the latest sign that Labour has been panicked by the Green Party’s popularity in the polls, Ms Mahmood will take a swipe at its leader Zack Polanski.
She is due to attack Mr Polanski’s ‘fairy tale of open borders’ in a speech later on Thursday.
The Home Secretary will directly criticise Mr Polanski for making a visit to a migrant support centres outside Calais last December when he helped re-fill water tanks and picked litter around the site.
He also said migrants should be allowed into the UK and handed the right to work as soon as they arrived.
‘A party leader who seeks the highest office in the land should not be on the beaches of France helping migrants onto small boats encouraging them to make a perilous crossing,’ Ms Mahmood will say.
‘Creating further incentives to come to this country illegally, increasing the already vast burden placed on taxpayers in this country, Polanski calls for the most expensive and expansive migration policies anywhere in the world.’
Ms Mahmood will also attempt to head off criticism from the Left of the Labour party, which would prefer migrants to be allowed into Britain through so-called ‘safe and legal routes’ which critics say would simply attract more arrivals.
‘Restoring order and control at our border is not a betrayal of Labour values, it is an embodiment of them, and it is the necessary condition for a Labour Government to achieve anything it hopes to,’ she is due to say.
Last year £4billion was spent on asylum support and at the end of December there were 107,003 migrants receiving hand-outs, including 30,657 living in asylum hotels on full board.
Shadow Home Secretary Chris Philp said: ‘Labour should put foreign criminals on a plane home, not onto British streets.
‘If Labour had a backbone and deported all illegal immigrants, there would not be the need for asylum accommodation.’
Tim Naor Hilton, chief executive of Refugee Action, accused Ms Mahmood of ‘bullying refugees for a bump in the polls’.
‘The Home Secretary already has the power to deny support and accommodation to people seeking asylum who are not destitute or who have broken the rules,’ he said.
‘This is the latest in a long line of announcements from successive governments that bullies refugees for a bump in the polls rather than try to solve the real problems faced by people and communities – poverty, homelessness, and the rise of the far right.
‘Ministers must end this dangerous race to the bottom and make the case for a UK that welcomes people fleeing war and torture and supports them to rebuild their lives here.’
