When a sponsor licence is revoked, UKVI will curtail any sponsored migrants’ permission to stay in the UK, usually to 60 days (or less if the migrant has fewer than 60 days leave remaining). If UKVI believes that the migrant was complicit in the breach, it will curtail permission to stay in the UK with immediate effect.
During this period, the individual will either need to make a new visa application before expiry of the curtailment period or leave the UK.
