Hi, i was just wondering if anyone could help me.

I am English and applied for a residency permit last week in Denmark and i am being told by people that i can not leave the country until my residency permit comes through. I am also being told i can leave Denmark why my residency permit is being done.
As Denmark is part of the EU i would have thought that i could leave while i wait for my residency permit?

Does anyone know if i am able to leave Denmark to return to England while waiting for my residency permit?

many thanks.
