The Danish Government has implemented extensive restrictions on entry to Denmark due to the Corona virus/COVID-19.
These restrictions mean that you must expect to be rejected at the Danish borders even with a valid visa.
The only exceptions are foreign travelers who have a valid visa AND a worthy purpose for entering. Worthy purposes include travelers who are either parents or primary caretakers (e.g. foster parents) of minors residing in Denmark, visits to critically ill family members, persons who are in the process of a medical treatment in Denmark, persons who are attending a funeral in Denmark, and persons who will be part of a court case in Denmark.
Ordinary tourist visits, family visits and business travel are not considered worthy travel purposes. Case processing times may be extended. For more information please visit the website for information from the Danish authorities: https://politi.dk/coronavirus-i-danmark/in-english
