No, the UAE e-visa system is designed for single entry. This means that each e-visa is valid for a single visit to the UAE within the specified period. If German citizens exit the UAE after using their e-visa, German citizens would typically need to apply for a new e-visa if they plan to re-enter the country.
German citizens may apply for a 30-day, 60-day, or 90-day tourist visa depending on the reason for their trip to the United Arab Emirates.
If you want to apply for other types of visas, please visit the nearest Embassy or Consulate.
