Most people who move to Barcelona do not fail because the paperwork is hard. They fail because they do it in the wrong order.

The settling-in process is a dependency chain, and nobody hands you the chain:

You cannot open most bank accounts without an NIE.
Many landlords will not sign a long-term rental contract without a bank account.
You cannot register with a CAP and get your CatSalut health card before you are empadronat.
The TIE fingerprinting appointment has a fixed legal window counted from the day you enter Spain.

So the newcomer who arrives full of energy and books "whatever appointment is available first" loses weeks. They show up at Extranjería missing an apostille, or at the Ajuntament without proof of address, and get sent home. The slot they lost took six weeks to get, and the next one is just as far away.

The questions that decide your route

Before you book anything, four answers change your entire list of steps:

Your citizenship. EU, EEA and Swiss citizens skip the visa and the TIE entirely and register for the certificate that carries their NIE. Everyone else starts with the visa and a residence card.
Your visa route. A digital nomad, a student and a relocated employee follow different steps, with different deadlines counted from arrival.
Your arrival date. Several deadlines are legal windows, not suggestions: the TIE has a fixed window after entry, and certificates such as the padrón stop counting for most offices after a few months.
Your household. Children add school pre-inscripció. A pet adds the import certificate. A partner with a different passport may follow a different route than you.

What Wellcomo does with those answers

Wellcomo turns the four answers into an ordered route: every tràmit that applies to you, sequenced so nothing is attempted before its prerequisite, each with a real due date counted from your arrival. Every step opens like an operating manual: the exact documents to bring, which ones need an apostille or a sworn translation, the office, the booking link, the cost, and the reasons people get sent home from the counter.

The first playbook on your route is free, forever. If you are actually moving in the next few months, Settling unlocks every playbook on your route, the document vault with expiry alerts, and one-click hand-off to vetted Barcelona providers for the steps you would rather not do yourself.

Answer the six questions and read your own route before you book anything else: build your route.
