Writing in 'The Times' newspaper, Prime Minister David Cameron warned that migrants who failed to improve their fluency in English after two years may face deportation.
New rules will mean that from October this year, migrants coming to the UK on a five-year spousal visa with poor or no English skills will have to take a test after two and a half years to show they are making efforts to improve their English.
Arguing that community cohesion is the best antidote to extremism, Cameron pledged to fund English language classes for female migrants.
"We will also fund a dramatic improvement in the way we provide English language services for women. With a new 20 million pounds programme, we will make sure every woman from isolated communities with no English at all has access to classes, whether through community groups or further education colleges," he writes.

He writes: "We must also make more progress on English language. It is at the heart of solving this. Consider this: new figures show that some 190,000 British Muslim women - or 22 per cent - speak little or no English despite many having lived here for decades.
"40,000 of these women speak no English at all. So it is no surprise that 60 per cent of women of a Pakistani or Bangladeshi heritage are economically inactive."
The Prime Minister said that English classes will be held in homes, schools and community centres with travel and childcare costs provided to encourage the maximum participation.
Segregation, the Prime Minister says, is allowing "appalling practices" such as female genital mutilation and forced marriage to exist, and increasing vulnerability to recruitment by so-called Islamic State (ISIS) terror group.
He also announced a review of the role of Britain's religious councils, including Sharia courts, in an effort to confront men who exert "damaging control over their wives, sisters and daughters".
Details of the new English language tests will be unveiled over the next few months.
