Deputy Philip Ozouf has pleaded guilty to immigration offences.
The St Saviour politician appeared in Jersey's Royal Court to admit five charges under the UK Immigration Act.
They relate to Rwandan nationals employed at his launderette between 2021 and 2023, without the necessary change of employment permissions.
Deputy Ozouf was External Relations Minister between July 2022 and January 2024.
He is now a backbencher, although he is currently suspended from the States Assembly for breaching the members' Code of Conduct over motoring offences.
Deputy Ozouf has been bailed to appear before the Royal Court in February to fix a date for sentencing.
In July, ahead of an earlier court appearance, he apologised to the States Assembly and his constituents:
"As a long-standing Member of this Assembly, fully cognisant of the need to uphold the highest standards of conduct in both public and private life, I express regret that this matter has arisen and how it may reflect on this Assembly.
