Digital Nomads: The AI engineer who left Nigeria for Germany and quadrupled his income

It was a chilly March morning in 2018 when John Robert stepped off a plane at Frankfurt Airport, marking the beginning of a new chapter in his life. Little did he know that this was just the first leg of a long journey that would take him from Nigeria to Germany, and ultimately, to a life of global mobility. For Robert, a young computer science student at the University of Ibadan in 2013, the desire to leave Nigeria was sparked by a simple yet profound observation: nearly all of Nigeria's biggest business leaders had spent time abroad, and it was this international exposure that seemed to be a recurring advantage.

As a 19-year-old, Robert was determined to follow in their footsteps. He began saving every penny he could, scraping together enough money to travel, with no particular destination in mind. But for Robert, the goal was clear: to become a globally mobile business leader. "The only way to do business in multiple countries, and have the knowledge to do so, is to actually leave my country, I thought, and to learn with people from other countries, to understand how they think," he said.

Fast forward to 2015, when Robert graduated from the University of Ibadan. By this time, Germany had become more than just an idea; it was a tangible goal with a price tag. Robert spent months researching universities, eventually applying for a master's degree in Data Analytics at Stiftung Universität, a public university in Hildesheim, northern Germany. Getting admitted was just the first hurdle, as Robert soon discovered that securing a student visa was a complex process.

The financial requirement was often the hardest part, as German authorities required prospective students to deposit about €8,000 ($9,400) into a blocked account (Sperrkonto) before issuing a visa. The money remained theirs, but it could only be withdrawn gradually after arrival to cover living expenses, Robert explained. This was a significant barrier, but Robert was determined to overcome it.

After months of waiting, Robert finally received his student visa and made the move to Germany. It was a culture shock, but he was determined to make the most of his time in the country. Robert settled into his new life, studying Data Analytics at Stiftung Universität and working part-time to support himself. It was a challenging but rewarding experience, and Robert soon found himself thriving in his new environment.

In 2026, Robert reflected on his journey, noting that he had quadrupled his income since leaving Nigeria. This was no small feat, and it was evidence of his hard work and determination. As an AI engineer, Robert had found a home in Germany, and he was living his dream. Yet, that dream began from a strong desire to become a globally mobile business leader, which still drives him to this day.

In recent years, Germany has introduced new immigration pathways, such as the Opportunity Card, to make it easier for international students to stay in the country after graduation. This has opened up new opportunities for students like Robert, who are eager to build their careers in Germany. However, the traditional route of securing a student visa and then applying for a work visa remains a complex process.

Robert's experience highlights the challenges that international students face when trying to navigate the German immigration system. Despite these challenges, Robert's story is evidence of the power of determination and hard work. By following his dreams and taking calculated risks, Robert was able to build a new life in Germany and achieve his goals.

As I reflect on Robert's story, I am struck by the importance of global mobility in today's world. In an increasingly interconnected economy, having the skills and knowledge to navigate multiple cultures and countries is a valuable asset. Robert's experience shows that with hard work and determination, it is possible to build a successful career in a foreign country.

However, Robert's story also highlights the challenges that international students face when trying to navigate the immigration system. As a writer, I believe that it is essential to tell stories like Robert's, to highlight the opportunities and challenges that global mobility presents. By sharing these stories, we can create a more nuanced understanding of the complex issues surrounding global mobility and immigration.

In the end, Robert's journey is evidence of the power of following one's dreams and taking calculated risks. As he looks to the future, Robert is confident that his experience in Germany has prepared him for a life of global mobility. And as I reflect on his story, I am reminded of the importance of embracing global mobility as a key driver of economic growth and development.

As Robert said, "I am living my dream, and I am grateful for the opportunities that Germany has given me."
