Yashika Bageerathi had been told she would be flown back from Heathrow at 5pm on Mother’s Day.
But with less than 24-hours to go, the 19-year-old learned her removal had been put on hold.

People protest against the removal of Miss Bageerathi
Miss Bageerathi was told by a Home Office official it was due to “technical problems” with the plane.
But campaigners fighting to prevent her removal said they think it was because the airline did not want to carry her in the face of protests.
More than 40 people took part in a demonstration outside Parliament on Saturday afternoon, and an online petition has received almost 155,000 signatures.
Lynne Dawes, the principal of Oasis Academy Hadley school in north London, which Miss Bageerathi’s attends, told Sky News: “We believe now that Air Mauritius refused to fly her.”
It comes after British Airways appeared to refuse to allow her to board a flight from Gatwick Airport last week.
Ms Dawes said: “I know a lot of people have signed our petition and are really supporting Yashika.
“I can only think that maybe they have listened to what people are saying, that they feel it’s wrong for Yashika to be sent back by herself, but we have no official information on this.
“This is one of the hardest things, it’s trying to understand what’s happening to Yashika and her family.”
She had spoken to Miss Bageerathi who was thankful not to have been sent back, but found the continuing uncertainty difficult.
Ms Dawes said: “It’s a sort of rollercoaster for her.
“One minute it’s good news, the next minute it’s bad news.”
Miss Bageerathi’s lawyers were now trying to understand what was happening and plan their next steps.
The campaign so far had been paid for by charitable donations.
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.
At school she was described as a first-class student, until she was detained at Yarl’s Wood on March 19.
Home Secretary Theresa May has said it would not be appropriate to “interfere” with the case.
