My knowledge of the situation comes from the (very extensive) coverage of the situation on TV and radio stations just across the German border (I was in Schleswig-Holstein when the changes were brought in) - so it may not necessarily be accurate or complete.

As I understand it Denmark has not left Schengen but has merely reintroduced identity checks for those entering the country from other Schengen countries - in much the same way as other countries have done for sporting fixtures and major political conferences, the only difference being that it's intended to be permanent.

While this media coverage mainly focused on aspects that were important to Germans (the effect on cross-border commuters, the inconvenience suffered by German tourists heading to Danish holiday cottages) there was no mention whatsoever of any changes to visa regulations - something which I'm sure would at least have got some fleeting coverage.

Have you tried to check with the authorities in Denmark, or a Danish government web site?
