Overstaying the Visa
If you come to Germany as a foreigner from outside the EU you require a visa. Only a few countries are exempt from this obligation. When you apply for a visa you have to explain why you want to enter the country and prove that you have enough money, that you have health insurance and want to return to your home country. Your visa is always limited. If you overstay your visa you count as illegal. Follow the story of a Colombian who came to Germany to study.
