What type of jobs are available for someone to help other countries in need?

Good morning Jalyssa!
If you are interested in working internationally in the nonprofit sector/Non-Governmental Organizations (NGOs) then there are a few things I would recommend.
1) Determine what part of the world or what issues are most important to you. That will allow you to narrow down what organizations you could research to learn more.
2) Research organizations online that do the work you are interested in. Don't just rely on a Google search, but take a look at organization and nonprofit excellence websites learn about what makes an organization effective. What is the impact they have had in the countries or issues they work on? Who do they partner with? Do they have a good reputation and do their partners have a good reputation for the work they do?
3) Learning another language is usually important to working internationally. If you are thinking about a specific area of the world, consider what languages they speak. In Latin America, Spanish would be a really important, but in Africa, the most common second language most people can learn easily in the US is French, but it's not the only language spoken. Both Africa and Asia (and Latin America to a lesser extent) have many more languages to choose from and depending on the kind of work you want to do, the language skill may be vital to have or a skill that an organization would prefer you to have. Either way, it would be a huge asset.
4) Use websites like Idealist.org, the US State Department, jobs4development.com (that was what came up when I searched "international nonprofit jobs" and read job descriptions to learn more about actual positions that sound interesting and what types of education or degrees are best for it--this will also clarify language skills that organizations are looking for.

Most positions will require a college degree and some may also be interested in individuals with masters degrees. The most common degrees you see in international nonprofit employees are economics, political science, public affairs and business management. It would also be worth considering a degree or a minor in international relations.

In the end, it really depends on what the issues are the speak to you most and the kind of job that would be fun for you. Because there are so many choices, narrowing the field will be the first step to helping you get there. Good luck!

Rachel's answer is thorough and spot on. The only thing I would add is to check out the Peace Corps for opportunities that may be of interest for you. The experience varies wildly by the location and type of work you're doing, so I would suggest finding a couple of past PC members to give you some advice on that.

It is also a good idea to get volunteer and study abroad experience while you're in college. This will give you a better sense of what type of work you'd like to do and where you'd like to do it.

As far as continue education, the nonprofit sector is becoming a lot more professionalize and you can now find graduate programs specifically for nonprofit management. I also second Rachel's suggestions for programs in public admin, international relations and business management.
