Legal Question in Constitutional Law in Texas

The attorney has to be admitted by the Court itself. I'm not sure such admission is technically a license. Before a lawyer can be admitted by the Supreme Court, he or she must be licensed to practice law in a U.S. state or territory, must be in good standing with the courts of that jurisdiction and must have been licensed for at least three years. You can find a list of the requirements, as well as instructions for applying, at http://www.supremecourt.gov/bar/barinstructions.pdf.
