International Programs
Probably the best and easiest way to work overseas are through programs like Council on International Educational Exchange (CIEE) and The British Universities North America Club (BUNAC). These programs provide you with a six month work permit, which you must obtain before you depart. Both of the programs also provide a handbook that offers information about job hunting and essential information to help, housing assistance, orientation, and ongoing support.
