Glenda Caesar, a mother of four and grandmother of 12, who came to the UK as a baby, lost her job as an NHS administrator in 2009 and faced deportation.
She was denied the right to work for nearly a decade.
And the scandal even affected her son, born in the UK in 1988 but denied a passport.
Ms Caesar now represents other Windrush victims in their campaigns for compensation.
“I am their voice. I will speak for them. I will challenge the ministers and the heads of these schemes,” she said.
“Compared to these other schemes coming forward, the minimum is £10,000 and the maximum is £70,000. Is that enough for people who have been affected for decades?”
