A foreigner residing in Germany may invite the following relatives:
husband/wife or registered civil partner if he/she is over 18 years of age. If the marriage was concluded at the time when the inviter was already living in Germany, then for the spouse to move, it is necessary that the inviter has had a residence permit in Germany for at least 2 years.
Underage children
Other family members of a foreigner, but only in exceptional cases to prevent difficult life circumstances. For example, if your parent is seriously ill and there is no one to care for him at home.
