The primary examples are service-related fields, but these can range across a number of different industries. For example, online trade schools that offer training in vocations such as plumbing or electrical work will continue to provide strong career opportunities for students wishing to enter a field that will remain strong.
Another big driver is the healthcare industry. Ongoing nursing shortages in a number of states have been a problem for several years due to an increasing amount of retirements. In addition, the ongoing growth in the senior demographic means that those working in senior care facilities in a variety of positions will be in strong demand.
Finally, there are always positions working with children that cannot be outsourced, including pre-school aides, teachers and childcare program assistants. These positions also offer the ability to have more job security due to union contracts. Keep in mind that those jobs requiring at least a bachelor's degree will offer a higher initial pay.
Or, if you would prefer your target audience to be somewhat older, outside and inside sales and marketing positions with firms generally require the ease with language and fluency in dealing with different audiences. Going back to school for these positions will also give students a stable industry in the United States.
If none of those options are appealing, it's important to note that technical fields like computer science or information technology may be outsourced, but there are still considerable opportunities for U.S. graduates. There will always be a need for U.S.-based liaisons and engineers and computer scientists.
