To obtain Permanent Residency (PR) in Denmark, you can apply through the Danish Green Card scheme or through family reunification.

1. Danish Green Card Scheme: This scheme is for skilled workers who wish to live and work in Denmark. To apply for this scheme, you must score a minimum of 100 points based on your education, language skills, work experience, age, and adaptability. You must also have a university degree or a vocational degree that qualifies you for a skilled job in Denmark. If you meet the eligibility criteria, you can submit an online application, and if your application is successful, you will receive a residence permit for up to 2 years, which can be extended for another 3 years. After living and working in Denmark for 4 years, you can apply for PR.
2. Family reunification: If you have a family member who is a Danish citizen or a PR holder, you can apply for family reunification. The family member must sponsor your application, and you must meet the eligibility criteria for the specific visa category. After living in Denmark for 3 years on a family reunification visa, you can apply for PR.

It is essential to note that the Danish Immigration Service assesses each application on a case-by-case basis, and meeting the eligibility criteria does not guarantee that your application will be approved. Therefore, it is recommended to seek the advice of a registered migration agent to ensure that you meet all the requirements and provide the correct documentation.
