Migration Watch UK have responded to Vote Leave's immigration plans, saying that a work permit for all migrants would be more simple and less bureaucratic, and lead to a reduction in migration.
Lord Green, Chairman of Migration Watch UK, said: "Work permits for all, EU and non-EU, is the way forward.
"This would preserve access to the skills our economy needs while reducing the population pressures which are simply getting out of hand."
There may be a flaw in Vote Leave's stance on immigration: While the Republic of Ireland will remain in the EU, Northern Ireland will not.
Yet Vote Leave say they do not want border checks between the two areas.

Immigration minister James Brokenshire has said "net migration from outside of the EU and within the EU remains too high".
It comes as latest official figures reveal it reached 333,000 for the year ending December 2015 - the second highest level on record. Net migration from the EU was estimated to be 184,000.
"These figures underline that there are no quick fixes or simple solutions," Mr Brokenshire said.
"However, we remain committed to reforms across the whole of Government to bring migration down to sustainable levels, which is in the best interest of our country."
He also insisted "leaving the EU is absolutely no panacea or silver bullet whatever some may suggest".
Former London mayor Boris Johnson, a prominent member of the Vote Leave campaign, has said latest migration figures reflect the "scandal" of politicians' promises over immigration.
He told ITV News: "I think they show the scandal of politicians continually promising year after year that they can cut immigration to the tens of thousands when they have absolutely no control providing we remain within the European Union."
"It's only if we vote to leave on June 23 that we can take back control of our immigration from the EU 28 countries and have a sensible policy that is based on the real needs of the UK economy," he added.
Net migration to the UK hit 333,000 in 2015, the second highest level on record, according to the Office for National Statistics.Read the full story ›
