Ngamba is unable to return to Cameroon because of her sexuality, with homosexuality in the country punishable with up to five years in prison.
However, after 15 years in England she has not been granted a visa or UK citizenship.
Five years ago she was on the verge of being deported after attending what she thought was a routine signing-on process to let authorities know she was still in the country.
Ngamba was arrested, along with her brother Kennet, and sent from Manchester to a detention camp in London, before being released the following day.
She said the “adversity” has made her “even stronger.”
“It will always humble me and make me even more hungry, determined and unstoppable,” she added.
“It’s been a lot of years – a lot of years of so many hard times and doubting myself and [being] alone. Having to pick myself up, hold my head high, believe there will be a light at the under of the tunnel.”
Before Paris 2024, GB Boxing unsuccessfully tried to add Ngamba to its ranks for the Olympic programme, even writing a request to the Home Office to grant her British citizenship.
But she won a scholarship with the IOC refugee team, and was the first female boxer to represent the team at a Games.
Ngamba made her amateur debut aged 20 in 2018 and went on to accumulate 26 wins and five losses.
She won the English national championships three times in that period.
“I’ve gone out there and proved the world wrong about me, proved the world wrong about refugees,” Ngamba said.
