who has the power to admit new states into the union
Admission to the Union The Admission to the Union Clause of the United States Constitution, oftentimes called the New States Clause, and found at Article IV, Section 3, Clause 1, authorizes the Congress to admit new states into the United States beyond the thirteen already in existence at the time the Constitution went into effect.
State of the Union Since Franklin Roosevelt, the State of the Union is given typically each January before a joint session of the United States Congress and is held in the House of Representatives chamber of the United States Capitol. Newly inaugurated presidents generally deliver an address to Congress in February of the first year of their term, but this speech is not officially considered to be a "State of the Union".[6]
