The Scottish Affairs Committee has launched an inquiry into how well the current system meets the country’s needs and how Brexit could affect it.
Immigration is reserved to Westminster, but Scottish ministers want powers to be devolved so a Scottish-specific policy can be developed.
UK ministers argue that this would create complications and harm business.
The Westminster committee said its inquiry would focus chiefly on Brexit and the likely implications for the free movement of EU nationals.
