If you want to work for the U.S. government and see the world at the same time, check with the U.S. Department of State. This government agency has hundreds of different job opportunities available for people who want to represent U.S. interests abroad. The government has 265 different embassies around the globe, as well as many other offices where people can work in civil service jobs.
Whether your background is in engineering, security, accounting, healthcare, management, IT or operations, there's probably a civil service position related to your skills. Civil service jobs not only give you the chance to travel, but many positions pay well and offer relocation, cost-of-living allowances and excellent benefits.
One caveat: If you haven't paid your taxes in a few years or you've broken the law a couple of times, you'll have to satisfy your wanderlust in a nongovernment gig. The U.S. Department of State requires all civil service applicants to undergo a rigorous security clearance process that can take two to four months. They might even interview your friends, family members and neighbors.
