Ask an Immigration Solicitor. Get an Answer ASAP.
Good morning, I am Lawyer Ak and I will be assisting you today.
Unfortunately due to him serving time unless he has strong grounds for him staying in the U.K. such British partner or child then he can look at applying on this basis.
What date did he enter the U.K. and what family does he have in U.K.?
Unfortunately as he has uncles this will not guarantee legal stay in the U.K. ❤️
*sorry computer typo
If he had been in the U.K. 20 years then he could look at available routes.
