The UK is made up of four states: Scotland, Wales and the north of Ireland have their own assemblies. A referendum is planned in Scotland over whether it should remain in the UK. If the referendum is passed, then there would be along period of negotiation and planning. The Scottish government will want the same arrangement that the Republic of Ireland has, where residents of one country have full rights in the other. I can't see this having any negative impact on students enrolling in this year or next year.
