The main obstacle to working abroad is obtaining a work visa. Most countries will not issue a work visa unless you have already secured a job in the country. The best option for short-term work abroad is to go through a student work-exchange program. For a fee ranging from $250 to $500, these programs will get you a short term work visa. These programs were not designed to launch participants into an international career, rather to provide a way for young people to essentially "break even" while traveling in a foreign country. Teaching English is another option if you'd like to work abroad for a longer period of time. The best way to enter the field is to take a certified TEFL or TESOL course. Courses can be taken locally, or in the country you'd like to teach in. The quality of TEFL/TESOL courses varies greatly. A good TEFL/TESOL course should be at least 100 hours long, and monitored by an external professional organization. Most course are four weeks long, and costs range from $1000- $3000. The CELTA (The University of Cambridge Certificate in English Language Teaching to Adults) is the most prestigious and widely recognized TESOL certificate.
