The charge comes into force this Thursday as part of a cost-cutting drive after UK Visas and Immigration (UKVI) gave a private firm the contract for its customer enquiries.

NHS and firms hiring foreign workers if the Tories – who want to cut net migration below 100,000 a year – win the general election.

“Theresa May is putting party politics ahead of the country’s well being and she should be ashamed.”
The move has been taken after outsourcing firm Sitel UK won the contract for running the enquiries service. It was already privatised and had been run by two separate firms.
Previously the service offered Arabic, Bengali, Cantonese, English, French, Guiarati, Hindi, Indonesian, Japanese , Korean, mandarin, Portuguese, Russian , Sinhala, Spanish, Tamil, Thai, Turkish, Urdu and Vietnamese.
Now it will offer English plus Arabic, Cantonese, French, Hindi, Mandarin, Russian and Spanish.
The Home Office stressed advice is available on its website, but admitted the cut to language services would affect 1 in 25 calls and e-mails to UKVI.
