The Commonwealth Immigrants Act 1968 (c. 9) was an Act of the Parliament of the United Kingdom. The Act amended the Commonwealth Immigrants Act 1962, further reducing rights of citizens of the Commonwealth of Nations countries (as of 2010, comprising approximately 1.9 billion people, including New Zealand, Australia, The Republic of India, Islamic Republic of Pakistan (which included East Pakistan province), some African nations including Nigeria and many Caribbean islands) to migrate to the UK. The 1968 Act was superseded by the Immigration Act 1971.
