New curbs on benefits for migrants and tougher rules on recruiters and colleges are part of a package of measures Downing Street hopes will show it is getting tougher on immigration.
ITV News Political Correspondent Emily Morgan reports:
The Government is consulting on plans to ban overseas-only advertising of jobs, by legally requiring employment agencies to seek applicants for posts in Britain.
New plans to restrict the number of JobCentre Plus vacancies automatically advertised on an EU-wide employment portal will also be floated.
Home Secretary Theresa May said: "We are building an immigration system that is fair to British citizens and legitimate migrants, but tough on those who abuse it or flout the law.
"The Immigration Act is a landmark piece of legislation that will make Britain a less attractive place for those who come here for the wrong reasons, and allow us to remove more people when they have no right to remain."
David Cameron has failed to fulfil his promise to get net migration down to tens of thousands, the shadow Home Secretary has said.
Speaking following the Prime Minister's announcement of fresh curbs on benefits for migrants, Yvette Cooper said Labour called for tougher benefit restrictions nearly 18 months ago.
"We need less talk from the Prime Minister on immigration and more action," she said.
"The Government should get a grip and finally implement Labour's proposals to stop the undercutting of wages and jobs for local workers by the exploitation of low-skilled migrant labour, including banning recruitment agencies that only hire foreign workers and pressing for stronger controls in Europe."
Writing in The Daily Telegraph, David Cameron said:
– David Cameron
We changed the rules so that no-one can come to this country and expect to get out-of-work benefits immediately; they must wait at least three months.
And we are announcing today that we are cutting the time people can claim these benefits for.
It used to be that European jobseekers could claim JSA (jobseeker's allowance) or child benefit for a maximum of six months before their benefits would be cut off, unless they had very clear job prospects... we will be reducing that cut-off point to three months, saying very clearly: you cannot expect to come to Britain and get something for nothing.
Taken together, this is about building a different kind of Britain - a country that is not a soft touch, but a place to play your part; a nation where those who work hard can get on.
European immigrants will only be able to claim benefits for three months unless they have serious job prospects under plans outlined by David Cameron.
The Prime Minister insisted the change would make it clear to migrants that they cannot get "something for nothing" in Britain and further address what he claims is the "magnetic pull" of the benefits system.
The plans will build on changes announced in January that mean European migrants have to wait three months after arriving in Britain before claiming out-of-work benefits.
After that three months, migrants will now only be able to claim benefits for three months unless they have "very clear job prospects" - a cut from the six months of claiming announced in January.
Radical Islamic cleric Omar Bakri Mohammed will not be allowed back into Britain, the Government has insisted after reports emerged he intends to claim asylum in the UK.
The extremist preacher faces the death sentence for running a terror cell in Lebanon and claims he has been tortured, according to reports. Family members have said they are launching an urgent appeal to allow him back into Britain under asylum laws.
A Home Office spokesman said: "Omar Bakri Muhammad was permanently excluded from the UK in 2005 on the grounds that his presence is not conducive to the public good.
"As Omar Bakri Muhammad is excluded from the UK, he will be unable to make a claim for asylum."
A Romanian man has been arrested on suspicion of assisting unlawful immigration, a Border Force spokesman said.
He added that eight Afghani nationals have also been detained and a criminal investigation has been launched by immigration enforcement officers.
The nine men were "lucky" to be rescued from the choppy seas as their vessel had lost power according to the RNLI Dover boathouse manager.
Tony Hawkins said: "The vessel had suffered engine failure and its occupants were drifting in choppy seas with a force four wind blowing.
He added: "They were lucky. They were drifting in an incredibly busy stretch of water with the wind picking up. We're glad everyone is safe and well.
"They were spotted by passing vessels concerned for their safety which called the Coastguard. The occupants were cold but didn't need medical attention.
Nine suspected illegal immigrants had to be rescued when they became stranded on a small inflatable dinghy in the English Channel.
With a force four wind blowing, the powered boat suffered engine failure about four miles east of Dover, Kent.
RNLI officials said those on board were "lucky" as they drifted in one of the world's busiest waterways.
Concerned people on passing vessels raised the alarm with the Coastguard after spotting the stricken boat at around 7.20am.
A survey of more than 3,000 Britons over immigration was published after unprecedented success for anti-EU Ukip at recent local and European elections presented major challenges for all three major political parties.
Some 95% told the survey to be "truly British" you must be able to speak English, while 74% said it is important to have been born in Britain to be considered British.

In an increasingly diverse, multi-cultural country, we might expect people to be more relaxed about what it means to be British, yet the trend is going in the opposite direction.
It is now harder to be considered British than in the past and one message comes through loud and clear, if you want to be British, you must speak English.
They want tougher rules on benefits and many are unaware of the policies that are in place to control immigration.
And 61% of British people think immigrants from the EU should have to wait three years or more before they are allowed to claim welfare benefits.
