Student Yashika Bageerathi’s school is making a last-ditch appeal to stop her being deported from Britain to Mauritius later today.
The 19-year-old has been told she will fly back to the Indian Ocean island at 5pm on Mother’s Day without her family.
Lawyers have already had one appeal fail, a spokesman for the school said.
Meanwhile, shadow immigration minister David Hanson said he will contact the Home Office asking them to review the decision.
Earlier, the teenager’s mother Sowbhagyawatee Bageerathi told Sky News: “She rang me again and she started crying, and then she told me she has to go on a flight on Sunday.
“I was shocked. I said ‘What Sunday?’ She said ‘this Sunday’. And then I said ‘Are you joking because this is Mother’s Day?'”
More than 40 people gathered in London on Saturday afternoon to protest against Miss Bageerathi’s deportation.
Miss Bageerathi came to the UK in 2011 with her mother and two younger siblings to escape alleged physical abuse by a relative, and claimed asylum in the summer of 2013.
She had been attending the Oasis Academy Hadley school, where she was described as a first-class student, until she was detained at Yarl’s Wood immigration detention centre in Bedfordshire on March 19.
It was hoped she would be released on bail from the centre this week, a campaign backed by her MP, David Burrowes who represents Enfield Southgate, and the teenager’s school principal, Lynne Dawes.
The campaign was dealt a blow on Tuesday evening when her mother, brother and sister were told they also faced the threat of deportation after receiving a letter from the Home Office telling the mother she had no grounds for appeal.
On Thursday, Home Secretary Theresa May said it would not be appropriate to “interfere” with the case.
Ms May told Sky News: “Yashika’s two claims to appeal against the decision on her asylum claims have been dealt with by the judges, they’ve been looked at by the judges and I don’t think it’s appropriate for a politician to interfere in that legal process.”
