How Volunteering Abroad Builds Global Citizens

Sometimes the best education doesn't happen in a lecture hall. For thousands of young adults, it happens in a classroom halfway around the world where nobody speaks their language.

AIESEC, the world's largest youth-run nonprofit, has been sending 18 to 30-year-olds abroad since 1948. The organization was born from a simple idea: if people understood each other across cultures, maybe they could prevent another world war.

Today, volunteers travel for four to eight weeks working on projects tied to the UN's Sustainable Development Goals. They teach English, support marine conservation, help with economic development, and work to challenge prejudice in communities around the globe.

Mary-Treesa Rozario from AIESEC's Sydney University branch sees it clearly. "The reason why conflict starts is that people don't understand each other," she says. Cross-cultural volunteering helps young people bridge those gaps.

Sarah Sepuldiva discovered this in Vietnam in 2025. Teaching English without speaking Vietnamese forced her to completely rethink communication.

"The biggest lesson I learned was patience," she says. She had to rely on careful listening, observation, and creative ways to connect with students who felt nervous about their English.

Her solution? She told them about her own language-learning struggles and joked that even native English speakers make mistakes. Their laughter showed her they felt safe enough to try.

Harry Kwon felt restless growing up in Perth after being born in Asia. At 19, he traveled to Jakarta to teach, ostensibly about English but really about diversity and stereotypes.

Indonesia's rich mix of cultures made those conversations real. Kwon used his own experience as someone raised in a foreign environment to help students think about difference and social harmony.

The Ripple Effect

The impact didn't stop when Kwon came home. The experience shaped his entire career path.

He went on to work for AIESEC Australia, helping other young people access similar programs. Now he works for an education philanthropy focused on developing young people for social impact.

"I learned the world is vast and also that I can make some kind of change," he says. "I also saw my privilege of living in Australia and what I had that many others around the world don't."

Most volunteers start with practical goals: independence, work experience, something strong for their resume. But Rozario says something shifts once they arrive.

After working in unfamiliar environments where they have to navigate language barriers and cultural differences, "the whole type of purpose in doing this exchange completely changes," she says. "It provides more meaning."

The point isn't that a few weeks overseas solves global inequality or climate change. The point is that it interrupts assumptions, builds empathy, and shows young people they can contribute to something bigger than themselves.
