When did Scotland gain its independence?

From whom, may I ask? Scotland never belonged to anybody but the Scots throughout recorded history until the Act of Union in 1707, when it became part of the United Kingdom. Will it ever regain its Independence? There is a small amount of agitation for it, but most Scots are content to remain part of the Union while reserving the right to hate the English. Following devolution in 1999, Scotland once again achieved having it's own, albeit devolved, Parliament. The Scottish Parliament has the powers to introduce new laws, address issues in relation education, crime, health and prisons, but has limited powers in relation to Immigration and issues with UK or international impact, eg. immigration.
