The Border Force has warned non-EU students that they would be removed if found working illegally beyond permissible 20 hours a week.
Chief immigration officer Alex Legg, from the UK Border Agency, said: 'Non-EU students are generally allowed to work up to 20 hours a week, but if people ignore the rules by working illegally we will find them and seek to remove them from the country.
'We will not tolerate illegal working which undercuts wages and can exploit vulnerable workers.
'The UK Border Agency is also targeting employers. We're happy to work with businesses to let them know what checks need to be done on staff, but those who do break the law should know that they will face heavy fines.'
The assertion comes as five Indians face removal from the country following a series of UK Border Agency raids in Fulham.
Acting on intelligence, the Border Force officers visited three stores owned by the Idea Bright DIY chain, two on Fulham Road SW6 and 1 in New Kings Road, on Thursday 12 January 2012, questioning staff to check they had the right to work in the UK.
The UKBA said: `Two men aged 34 and 21 were arrested for working in breach of their student visas at the New Kings Road store, while a 26-year-old man was also arrested for working in breach of his visa at the store at 672 Fulham Road.
`At separate premises at 772 Fulham Road a 22-year-old man was arrested for working in breach of his student visa, while a 29-year-old was arrested for obtaining leave to remain by deception.
`All 5 Indian nationals are now in detention awaiting their removal from the UK.
`Idea Bright Ltd were served with notices telling them that they face fines of up to £10,000 per illegal worker unless proof is provided to the UK Border Agency that the correct right-to-work checks were carried out’.
