In a situation where both parties were willing, Tesla and the intelligence personnel signed a scholarship agreement.
During the years Tesla studied at Graz University of Technology, Spain would provide sufficient annual scholarships to support Tesla's studies, including funds for purchasing various materials and conducting small experiments.
In return, after completing his studies, Tesla needed to immediately go to Spain, and upon acquiring Spanish nationality, he could work or further study at the Royal Academy of Sciences and other universities.
If Tesla wished to study at prestigious universities in other European countries, Spain could arrange that too. However, the prerequisite was that Tesla would join Spanish nationality after completing his university education, something the intelligence personnel had explained in advance and Tesla had agreed to.
