Who is allowed to come to live in the UK? 4K

UK net migration hit 606,000 in 2022 - the highest figure ever recorded, according to the latest estimates from the Office for National Statistics (ONS).
The rise is driven by people arriving from non-EU countries on government-issued visas to study, work or join family members.
The figure includes Ukrainian and Hong Kong citizens for whom the UK government opened special schemes.

Immigration is a top issue for many developed countries so this should be reg, but the selection process, lets discuss that.
