In which cases will my right of residence for Germany expire?
Please note that your residence permit may become invalid under certain conditions. This would for example apply if you stay abroad for more than 6 months. In case you should plan a longer stay abroad for a certain reason, please ask your aliens (registration) authority (for information/advice) in advance. The authority will examine whether it is possible to grant you a longer period for your re-entry which is only possible in certain cases.
If the requirements for issuance become obsolete during a valid residence permit (e.g. in case of a separation of spouses in the case of a residence permit for the family reunion or in case the employment for which the residence permit was issued is terminated), please immediately contact the competent aliens (registration) authority. The authority will examine whether it is possible to issue a residence permit to you for other reasons.
