There are two evaluation rounds associated with the application process. Entrepreneurs, investors and academics are on the panel of judges who assess your application. Criteria such as business connections, previous experience and the market size of your chosen project are weighted to your application.
To enter to visa program Spanish is not a requirement, however learning the basics is highly recommended. All program communication will be conducted in English.
If accepted onto the program you need to ensure you bring all documentation required by your local consulate. Your close family members (spouses and/or children) will also be eligible to get visas.
