The Tier 2 category of visas, a route used by many Indians and other nationals from outside the EU, will undergo major set of changes under the new rules.
Companies in the UK hiring workers from outside the EU, such as Indians, will have to shell out an additional £1,000 annual Immigration Skills Charge, announced in March last year.
"Set at £1,000 per employee per year, and a reduced rate of £364 for small or charitable organisations, it (Immigration Skills Charge) is designed to cut down on the number of businesses taking on migrant workers and incentivise training British staff to fill those jobs," the Home Office said, in reference to the new levy.
An exemption to the charge will mean that it will not apply to PhD-level jobs and international students switching from student visas to working visas - "a key protection to help retain the talented workers and students who are vital in helping the British economy grow", the Home Office added.
The latest charge is among a wider changes made to the Tier 2 visa regime in an effort to cut immigration numbers from countries outside the EU and tighten visa regulations.
Most recently, the government had announced that professionals such as teachers, nurses and social workers from countries like India who apply for a Tier 2 visa to live and work in the UK will need to provide a certificate from their home country authorities with their applications disclosing whether they have any criminal convictions.
Under plans becoming effective from this week, skilled migrants applying within the Tier 2 category for these specific professions will now be required to provide a criminal record check certificate from any countries they have lived in for more than 12 months in the past 10 years.
An applicants partner, or a partner wishing to join an existing skilled migrant worker in the same sectors, will also be asked to produce a certificate.
The requirement could be waived where it is deemed not "reasonably practicable" to obtain a certificate, such as if a country or authority does not produce such documents.
Some of the other changes include those applying for a Tier 2 Intra-Company Transfer (ICT) visa being required to pay a health surcharge of 200 pounds per person per year.
Any dependents of the main applicant will also have to pay around the same amount as the main applicant.
The minimum salary level that UK-based sponsors can offer a Tier 2 (General) worker has been increased from £25,000 to £30,000 for experienced workers.
Some jobs in the health and education sectors are exempted from this higher threshold until July 2019.
The Tier 2 (ICT) Short Term Staff category has been closed, which implies that all workers applying under this route, except graduate trainees, must qualify under a single salary threshold of £41,500.
The latest rules are part of a number of tougher measures being introduced after a review by the UK's independent Migration Advisory Committee recommended changes to the visa system last year.
It has already been announced that the minimum salary threshold before a Tier 2 visa is granted to skilled workers from outside the EU will rise from £20,800 a year to £30,000 for most jobs.
Also, chemistry teachers are being removed from a list of UK "shortage occupations" but those who teach combined science, computer science and Mandarin are being added to the list.
Jobs on the shortage occupations list imply relatively easier visa norms for applicants from outside the EU.
