United Kingdom home secretary Sajid Javid said it would be the "biggest shake-up in 40 years" to the country's immigration system, during a Wednesday morning radio interview with BBC Radio 4's Today programme.
The existing rights of Swiss and British nationals already residing in each other's countries when Britain leaves the European Union will be guaranteed post-Brexit, the Swiss government has said.
They added: "We fully expect to get a deal and believe that is the most likely outcome - that is what we are focused on delivering".
Concern about the long-term social and economic impact of immigration helped drive Britain's 2016 vote to leave the European Union after large numbers of people, especially from poorer member states in eastern Europe, moved there to live and work.
The think tank also warned that the fact the low-skilled worker visas will be valid for 12 months could be a way of "fiddling the immigration figures", as they only include migrants set to stay in the country for over a year.
The government, which will introduce its post-Brexit immigration legislation to parliament on Thursday, said it planned to speed up the processing of work visas and reduce the burden on businesses sponsoring workers.
Saffron Cordery, deputy chief executive of NHS Providers - an umbrella group for Britain's state-funded health care system - said the health sector was "deeply concerned" about the planned changes.

High skills does not equal high pay. "They lay in those staff under £30,000".
The temporary workers' scheme would be "tightly constrained", the government said, with no rights to settle, bring dependents or access certain public funds.
'It will be a single system that welcomes talent, hard work and the skills we need as a country'. Meanwhile, EU citizens would not need a visa for visits of up to six months.
May has repeatedly said that if her deal is rejected then the world's fifth-largest economy might have to leave without a deal - the nightmare option for big business - or that Brexit might be thwarted altogether.
Speaking in the Commons, Ms Abbott said the government's "rhetoric about a global Britain was not enough" and ministers must take steps to "dismantle the hostile environment" it had encouraged to deter migrants.
"If the Government won't rule it out, then Parliament needs to find opportunities to stop the country reaching the cliff-edge by accident, starting with the Finance Bill in the first week back, then looking at every other legislative opportunity too", explained the Yorkshire MP.
The MAC's report, published in September, concluded that the new system should make it easier for higher-skilled workers to come to the country.
