No, it doesn't because there is no language in the constitution which includes it. That's how the constitution works. I challenge you to quote the passage which includes this, unless all you have is an emanation from the penumbra of a power actually included in the language of the document.
It's implied. Permission is needed for every other change in status. Leaving entirely as well.

I challenge you to show me where it says only powers explicitly stated in the Constitution are reserved to the United States. You can't. Whether or not a power is granted or denied depends, as Chief Justice Marshall noted, on a fair construction of the whole instrument. If Congressional approval is needed for a state to join the Union to begin with, and to change borders or split up or combine with another state once admitted, then it doesn't take a rocket scientist to conclude that approval must be needed to leave as well. Chief Justice Chase believed that. James Madison believed it. I don't see much in that to disagree with them.
