The post-Brexit government immigration system would cost employers more than £ 1 billion in administrative costs over five years, hurt the higher education sector by pushing students out of the EU, and risk a new scandal in the future. the Windrush, according to an analysis of the plans.

The Global Future report, a think tank that supports more open immigration, indicates that the NHS would also incur additional costs of nearly £ 120 million a year to recruit foreign staff in accordance with the system set out in the White Paper. l & # 39; immigration.

The long-delayed plan imposes the same minimum wage of £ 30,000 a year on European citizens wishing to work in the United Kingdom, which already applies to people outside the bloc, as well as various visa fees and other charges.

Using Home Office modeling for the number of people likely to apply for a visa of different durations and an average cost calculated for employers of around £ 12,500 per EU citizen, the study presents a five-year total of £ 1.14 billion, including £ 337 million in the public sector.

The study estimates the cost for the NHS separately by using figures showing the likely number of EU workers needed as part of the long-term plan for the service, as well as the fees and other costs they will have to bear. This would represent, he said, 118 million pounds a year.

Will the proposal solve something?

The suggested extension of the transition period is a new idea put forward by the EU to help Theresa May fill the circle created by the written agreement of last December and the draft agreement of withdrawal in March.

This forces the United Kingdom and the EU to ensure that there is no divergence between Northern Ireland and the Republic of Ireland.

But, after an intervention by the Unionist Democratic Party, the UK (and not the EU) has pledged not to have trade disputes between Northern Ireland and Britain.

The problem is that they are two irreconcilable chords. They also encroach on the legally binding agreement on Good Friday, which brought peace to Northern Ireland and, in some respects, pooled the sovereignty of Northern Ireland, giving citizens the right to birth, to be Irish or British, or both.

If the United Kingdom leaves the European Union with the customs union and the single market, the Irish border becomes the only land border between the United Kingdom and the European Union, imposing customs controls, fiscal and regulatory.

The backstop is one of the three options agreed between the EU and the UK in December and would only occur if Option A (Global Agreement) or Option B (Customized Solution) could not be approved by the end of the transition. The Irish have compared it to an insurance policy.

The new idea of ​​the EU is to extend the transition period to allow time for options A or B.

But an extension is problematic for Brexiters and voters who want the UK to come out of the EU as quickly as possible.

The Irish and the EU will also need the support of the disengagement agreement, which must be signed before the trade agreement can be undertaken. Otherwise, it's a Brexit without compromise.

Extending the transition to 2021 would mean another year of contribution to the EU budget. Great Britain should negotiate that, but it has been estimated between 10 and 17 billion pounds.

Staying in the European Union for a year would also mean freedom of movement and European jurisdiction, which the Brexiters would oppose.

It also indicates that the threshold of £ 30,000 could eventually leave up to 100,000 vacancies in the social care and nursing fields and cause difficulties in many other sectors.

EU students who decide to settle in the UK would incur visa and health fees of nearly £ 1,300 over three years, says a think tank, a total of 80 million £ per year for the entire sector.

The report also states that by requiring UK nationals enjoying the freedom of movement to prove their status, the system may reflect the Windrush scandal, according to which British nationals of Caribbean origin who lived in the United States United Kingdom for decades were deprived of deported due to lack of documentation.

This could happen again due to a lack of awareness, home office errors and technical issues such as people having spent time outside the UK.

Fergus Peace, researcher at Global Future, who drafted the report, said the white paper "represents an unambiguous shift towards a more complex and burdensome immigration system that will hurt our country's prospects."

"The government is bringing an end to free movement as the grand prize at the center of its Brexit strategy, but in the end, this white paper is a plan to isolate us from the world. It's not something to celebrate. It's a terrible mistake.
