False. Once a territory becomes a state, it does have the ability to leave the United States if it chooses to do so. The process of a state leaving the US is called secession.
One example of a territory leaving the United States is the case of Texas. Texas was its own independent country before joining the United States, and it later seceded from the Union in 1861 to join the Confederate States of America during the Civil War.
