Spouses must apply for a National (Type D) Family Reunion Visa through the German Embassy or Consulate in their country of residence (e.g., Canada). The application involves submitting completed forms, marriage certificate, proof of A1 German proficiency (unless exempt), sponsor’s residence permit, income proof, and health insurance. After the visa is issued, the applicant must register in Germany and apply for a residence permit. Spouses are generally eligible to work upon arrival if they meet all conditions.
