The woman, who cannot be identified, was originally refused
residency by the Home Office.
At her appeal, which took place in London, she asked to stay on
the basis she was "out" and could no longer conceal her
sexuality.
According to the BBC, she told the tribunal that while in
Jamaica a group of men had threatened to "convert" her - implying
they would rape her.
So-called corrective rape is a common problem both there and in
similar countries.
The woman, who is now based in the Midlands, also claimed she
suffered clinical depression as a result of her home country's
lacking tolerance towards gays and lesbians.
Her lawyers argued that if she returned to Jamaica she would be
living as a single woman with no "heterosexual narrative" - and
would therefore be exposed to continued risk.
Allowing her appeal, senior immigration Judges Gleeson and
Spencer said that any return to discreet living would be because of
her fear of persecution rather than "by reason of social
pressures".
