Here's a revised version that improves clarity and flow while maintaining the informative content:
Although South Africa only began recognizing refugees in 1993, it now hosts one of the world's largest refugee and asylum seeker populations. While many refugees arrive hoping to drastically improve their lives, most struggle to find employment, earn sustainable incomes, and access social services.

Unlike many African countries, South Africa operates without refugee camps. Refugees and asylum seekers live in urban communities and largely fend for themselves. When assistance is needed, they must navigate local government structures independently. This reality has created a critical need for professional social services to support this vulnerable population.

Our refugee internships suit candidates with strong interests in social services, understanding of refugee challenges, and/or backgrounds in human rights, development studies, international relations, or law.
