Consular officers, being nominally more distant from the politically sensitive aspects of diplomacy, can more easily render a wide range of services to private citizens, enterprises, et cetera. They may be more numerous since diplomatic missions are posted only in a nation's capital, while consular officials are stationed in various other cities as well. However, it is not uncommon for individuals to be transferred from one hierarchy to the other, and for consular officials to serve in a capital carrying out strictly consular duties within the "consular section" of a diplomatic post, e.g., within an embassy. Some countries routinely provide their embassy officials with consular commissions, including those without formal consular responsibilities, since a consular commission allows the individual to legalize documents, sign certain documents, and undertake certain other necessary functions.
