Detailed description
As a Swiss citizen, you are exempt from the requirement for a residence permit due to the Agreement on the Free Movement of Persons between the EU, its member states and Switzerland, but you can apply for a residence permit to be issued as an electronic residence permit (eAT) if you wish. Your right of residence exists as long as you meet the requirements specified in the agreement. This is the case, for example, as long as you are employed in Germany, study here, are self-employed or can simply live on your savings here without state aid.
Your family members who are not Swiss nationals must report their stay to the Office for Foreigners' Affairs within 3 months of entering the country.
If there is a right to freedom of movement, the Swiss residence permit will be issued.
