Some of the biggest businesses operating in Britain also told the MAC what they believed the impact would be if the minimum salary threshold was increased.
Tata Consultancy Services, an Indian IT services giant that employs hundreds of people in the UK, said higher salary thresholds would likely force it to cut costs by providing "off-the-shelf," rather than customised, solutions for its clients.
PwC told the MAC that increasing salary requirements would force firms to set up and expand in other parts of the world.
Chancellor George Osborne proposed a new "skills levy" on employers giving jobs to foreign workers in his emergency summer budget last month.
The MAC is expected to publish a wider review, taking into account the impact of a skills levy, in December.
