DD is moving to Germany for a year as she's doing a year abroad under her uni course, so this isn't really holiday related.
She's renewed passport, got proof of uni course and accommodation, insurance (including health), a Ghic on the way, got FFP2 masks, had her second vaccine two weeks ago (Dr kindly agreed to let her have early). She has to fill in a digital form and university have told her she can apply for a residence permit once she's there. Anything else she might have overlooked?
