How can a Business Visa holder become a citizen?

The annual GDP (Gross Domestic Product) of Germany surpasses $4.5 trillion. It has the fourth-biggest economy in the world and the largest in Europe. The image of the country is overwhelmingly pro-business and pro-immigration. In 21 or 33 months, investors can apply for permanent resident status, often known as settlement permits. They are eligible to apply for German citizenship and a German passport after eight years. A German passport entitles its holder to visa-free travel to 188 countries as well as unrestricted mobility inside the EU.
