Summarize this article in one sentence.
Many overseas jobs will not consider you for a position unless you already have a visa or work permit organised. Be sure you understand the requirements for a visa or work permit and know that you will be able to meet them before thinking seriously about applying for a job abroad. The embassy of the country you want to work in will provide information for applying for a Visa.  Ensure you have a full and valid passport before inquiring about a visa. You can also look online for visa requirements and application cycles for different countries. Country specific information is provided on the website of the US State Department. Finding a job abroad can be a difficult prospect. You have to demonstrate not only that you are a good person for the job, but that you can offer something more than the prospective local candidates who will most likely take less time to adapt to the new working environment. Because of this, and the difficulties of breaking into a foreign working culture, it is especially important that you utilise your contacts and networks as much as possible.  Use online networks as well as your college alumni association to create contacts with people working in your field abroad. Once you find people who have made the move abroad successfully, ask them for advice and guidance on how you can do the same. The language requirements will vary depending on the type of job you are interested in getting. For example, if you are working for the US government abroad you may find that the majority of people in your office are American and business is conducted solely in English. If you are applying to work in a foreign firm you will probably be expected to be able to work in the native language.  Ensure you know the expectations and can meet them before you apply for a position. Even if you do not need to be fluent in the local language to get a job, having a command of basic phrases at the minimum will make life abroad easier. If you are not required to speak the local language you should make it clear in your application that you are keen to learn and will take evening classes once you arrive.
Apply for a visa and/or work permit. Make contacts and use your networks. Consider the language requirements.
