I work with Physisists, Biologists, PhD Doctorate types. Their title will forever be Doctor or Dr. No matter where they travel, the acceptable term of address is Dr. LaserTex, or whatever.
A Medical Doctor, MD, has still completed the requirements to have the title of Doctor or Dr. Wherever they go, they are a Doctor. They are not allowed to practice medicine except where they are licensed, but their title is still Doctor.
A CHL in Texas allows you to carry concealed in Texas (within the law). Some states have agreed that the training and requirements that you completed in Texas is good enough for you to carry in that state too. You CHL does not allow you to have your gun in Chicago. Only criminals can have guns in Chicago because the mob doesn't want the competition.
Did that even come close to hitting your question?
