What is the longest time to be an illegal worker in Britain?

Being a black worker in Britain can get the status at 13. Immigrants who work illegally in England and Wales may face six months' imprisonment, according to the proposed immigration bill. For 20 years in a row, the age of black households in most countries is 10-20 years old, but it depends. For example, many black households who had no identity in Britain in their early years obtained their identity in 10, and some were expelled immediately after being discovered by the government.
