A Ukrainian-born woman who became the first pupil from a Lincoln school to go to Oxford University is fighting a decision to deport her.
Eleonora Suhoviy has to wait a month for the judge's ruling
Eleonora Suhoviy, 24, came to England aged 13 in 1994 and went Yarborough School, a city comprehensive.
The Home Office decision to deport her was made in 1999, when she started her Modern Languages course in Oxford.
Her appeal against this was heard at an asylum and immigration tribunal she must wait a month for the ruling.
Ms Suhoviy was awarded a scholarship to study at Oxford by Lincoln Cathedral and graduated with a 2:1.
Her ambition is to be an intelligence officer in the Royal Navy and currently she works as a personal assistant to cancer specialists at the John Radcliffe Hospital.
She said: "It's been emotionally very draining. Everything to do with the case - it was upsetting and hurtful to receive those letters.
"And although I do understand on a mental level they are part of a procedure, you can't help responding personally to it.
"[If I was deported] it would be the most horrid thing that has ever happened to me in my life. I would feel that I have no home, that I'd been thrown out of the place I feel I belong to."
Ms Suhoviy's barrister, Jonathan Goldberg QC, said: "I found it an honour to accept this case without fee because she is such a brilliant, patriotic and worthy young woman."
A Home Office spokesman said: "We can't comment on individual cases but there is an independent appeals which enables full and proper representation in immigration cases.
"We will only seek to remove an individual when all appeal rights are exhausted and they have no further claim to remain in the UK."
