Swedish authorities: what comes first
The question everyone has at the start: where do I begin? The steps depend on each other — no personal identity number, no bank account; no bank account, no BankID; no BankID, almost nothing. Pick your situation and the chain sorts itself.
Your citizenship
How long are you staying?
What brings you here?
Children coming too?
This chain gives you the order. What it can’t answer is your exact case — which proof your employment contract counts as, what happens if you move mid-tax-year, how to go on from a sublet without a first-hand lease.
For that there’s a free 15-minute intro call. If it gets specific after that, 50 € an hour.
