From 1 July 2021, EEA and Swiss citizens must have a visa to remain in the UK for longer than 6 months, and to work, study or be self-employed. Employers will need to obtain a sponsor licence to employ EEA and Swiss citizens unless they have a visa which allows them to work in the UK.
After Brexit, compliance with immigration legislation and right to work checks and obligations will be noticeably more onerous for employers. They could be visited by Home Office immigration officers and audited. Recruitment timeframes and costs will increase.
End-to-end, the sponsorship process takes 3 to 4 months from getting the licence to the employee starting work, and costs in the region of £10,000 in Home Office fees alone for a 5 year visa.
In contrast, EU Settlement Scheme (EUSS) visa applications can take just two days, and have no application fee.
