The government has introduced reforms to restrict care workers from outside the UK from bringing family members.
Care providers are also required to register if they are sponsoring migrants.
They said it is part of the government's plan to "bring down unsustainable levels of legal migration."
Care providers in England acting as sponsors for migrants will also be required to register with the Care Quality Commission (CQC) – the industry regulator for Health and Social Care.
It forms part of a wider package of measures, which means a total of 300,000 people who were eligible to come to the UK last year would now not be able to do so.
Home secretary, James Cleverly MP, said: "Our plan is robust but fair – protecting British workers while ensuring the very best international talent can work and study here, to add value to our society and grow the economy."
These changes come into force as the government is set to lay rules in Parliament later this week to prevent the "continued undercutting of British workers", which includes raising the salary threshold that a skilled worker must meet in order to get a visa and removing the 20 per cent ‘going-rate’ discount for migrant workers in shortage occupations.
From 4 April, the minimum salary required for those arriving on the Skilled Worker visa will increase from £26,200 to £38,700.
The government said this will further drive down numbers, reduce pressure on public services and prevent the undercutting of British workers by employers who look to recruit cheap labour from overseas.
The minimum income requirement for family visas will also rise, starting at £29,000 from 11 April. By early 2025 this will be increased to £38,700, in a bid to ensure dependants brought to the UK are supported financially.
While the government said they are introducing these reforms to protect British workers, some think they could have a negative effect on the care workers.
Chief executive of Scottish Care Donald MacAskill told STV that the decision "could have a potentially devastating impact."
He said: "This is a very hostile approach based on a hostile model of migration."
