Any debate over levels of immigration to the United Kingdom must address the filling of the "skills gap", according to the Recruitment and Employment Confederation.
Rec chief executive Kevin Green said: "The UK's jobs boom continues with vacancies increasing as employers look for new workers to meet increasing demand and to replace staff that have been snapped up by competitors.
"The big issue remains that employers are finding it hard to find the talent and skills they need, yet we still have 2.2 million unemployed people in the UK.
The political debate around immigration must acknowledge this skills shortage.
Now is the time for government to reform the visa system to ensure that the UK retains a flexible labour market so our businesses can grow and create more jobs."
