A D2 Visa allows you to stay in the Schengen Area for study or research, but it does not allow free travel within the area.
A D2 Visa allows you to stay in the Schengen Area for a specific period, usually for study or research purposes. However, it does not grant you the right to travel freely within the Schengen Area. If you wish to travel within the Schengen Area with a D2 Visa, you may need to apply for a separate Schengen Visa depending on the specific travel regulations of the countries you plan to visit. It is important to check with the respective embassies or consulates of the countries you intend to travel to ensure you have the necessary visas in place before embarking on your journey.
