British Prime Minister David Cameron will tighten restrictive measures for EU migrants coming to work in Britain, starting Wednesday.

Anyone from the European Union coming to the UK in search of a job will have to wait three months before they can claim benefits, the PM will announce. The new controls will come into force January 1, 2014 amid growing public concerns of an influx of Romanian and Bulgarian workers once restrictions are lifted on the two countries at the end of 2013.

PM Cameron said the public was “rightly concerned” that migrants may come to the UK to “exploit our public services and benefits system”, The Independent reported.

“As part of our long-term plan for the economy, we are taking direct action to fix the welfare and immigration systems so we end the ‘something for nothing culture’ and deliver to people who play by the rules”, he added.

Cameron stressed that accelerating the start of these new restrictions will make the UK a less attractive place for EU migrants who want to come here and try to live off the state.

“I want to send the clear message that whilst Britain is very much open for business, we will not welcome people who don’t want to contribute”, the Prime Minister concluded.

David Cameron has already announced other restrictive measures that will take effect 1 January. They include cutting off benefits after six months for EU migrants with no job prospects, suspending housing benefit claims and imposing a 12-month re-entry ban for people who have been removed.
