Halliburton tries to work more and more with citizens of their own countries. But I think it's important for US business students to go overseas. It's an excellent idea. It opens more doors. If we're hiring for a department which is totally international, then they've already had the experience and the exposure, which is an added benefit.
Language is also important.
Language could be a step-up on someone else competing for a job. The best overseas experience you can probably have is relevant work experience, the exposure of working in a foreign country. It doesn't always matter which country. Just because you had it in Europe doesn't mean that's the only location we'd send you. Generally, the benefit of an overseas experience is that it provides a totally different type of education.
