Foreign Service brat

In the United States, a Foreign Service brat (also referred to as diplobrat or FSB) is a person whose parent(s) served full-time in a Foreign Service posting abroad during that person's childhood. The term "brat" is often thought of as derogatory; however, for some who have experienced this background, the term has a neutral feel and is sometimes taken as a sign of pride. A Foreign Service brat may spend the majority of their childhood outside their parents' home country.
Like similar groups, such as military brats, missionary kids, or other third culture kids, Foreign Service brats are faced with frequent moves, and possibly the absence of a parent. Some Foreign Service brats will grow up to take on roles similar to their parents, while the majority will pursue a private sector career. Many of these children feel very different from their peers if they are eventually "repatriated".
