Who must sign a bill granting statehood to a territory?

The U.S. Constitution gives Congress the power to grant statehood but does not establish the process for doing so. Congress is free to determine the conditions of statehood on a case-by-case basis.

According to the Constitution, a new state cannot be created by splitting or merging existing states unless both the U.S. Congress and the legislatures of the states involved approve.

In most past cases, Congress has required that the people of the territory seeking statehood vote in a free referendum election, then petition the U.S. government for statehood.

I hope this helps :D
