Permanent residence

You can apply once you meet the core requirements, and residence time is only one of them. The others are a stable attachment to the labour market, self-sufficiency, and passes in the Danish language tests and the citizenship test (indfødsretsprøven). The minimum period of residence is either 4 or 8 years depending on your situation.

So the timing is not simply a matter of counting years. It is a matter of whether every requirement is satisfied on the day you apply. Applying at the earliest possible point, after 4 years, means the basic and the supplementary conditions all have to be in place by then.

The rules here are technical and they change, which is why it is worth having the case checked before the application goes in. A refusal you could have foreseen costs time you do not get back.

In our experience the employment requirement accounts for most of them. It is the requirement that catches people out, and it does so most often where the applicant is self-employed or runs a sole proprietorship, because proving the work in those cases is harder than simply producing payslips.

After that come errors in the documentation itself. They do not have to be large. A file that is incomplete or inconsistent gives the authorities a reason to refuse without ever reaching the substance of the case.

Having the case reviewed before submission is the cheapest way to deal with both. It improves the odds of approval and, because there is less going back and forth, it often shortens the processing time as well.

The authorities look at whether you are genuinely running a business and putting in work equivalent to full-time employment, which in practice means somewhere around 120 hours a month.

You therefore need to show two things at once: that the business is active and financially real, and that the hours behind it are yours. What carries that is the paper trail as a whole: annual tax returns and accounts, the VAT filings behind them, invoices raised, and bank statements showing the money actually moving.

What makes these cases awkward is that the Danish Immigration Service assesses the overall picture rather than the income figure. We see sole proprietorships with quite healthy revenue refused, and businesses turning over very little approved. The assessment is individual to a degree that makes comparison with other cases unreliable.

Which is why the useful question is not whether your business earns enough, but whether what you can document adds up to full-time work in the way the authorities read it. That is worth establishing before you apply.

Mostly by getting the case right before it is submitted, which is where both the outcome and the processing time are decided. An application that arrives complete and properly documented gives the Danish Immigration Service less reason to come back asking for more, and that alone can take months off a case.

Before anything is sent, the requirements are worth going through one by one: residence period, employment, self-sufficiency, language. The point is to establish whether you actually meet them, rather than finding out from a refusal.

During processing the work shifts to answering the authorities. Requests for further information have to be handled properly and promptly, because a slow or partial answer is one of the more common causes of delay.

And where a case has stalled without good reason, it can be chased. Asking for a decision is sometimes the only thing that moves a case that has been sitting still, which is worth knowing on long-running matters.

There is a window here, and it is narrow. You cannot apply before you turn 18, and to use the more favourable rules for young applicants the application generally has to be in before you turn 19. In practice that means applying soon after your 18th birthday, as soon as the requirements are met.

What the youth route offers is an exemption from the employment requirement, which at that age is usually the impossible one. What it asks in return is an unbroken run of schooling, sometimes alongside work. You are expected to have moved through your schooling without significant interruption.

Take that literally. Even a short break, or one that has not been explained, can cause problems in the assessment and in the worst case decide the case against you, because the authorities look at whether the requirements have been met continuously rather than eventually. A pass in Prøve i Dansk 2, or a Danish language exam of the same level, is normally required as well.

Because the rules are technical and the deadline is unforgiving, this is one to look at early rather than at 18 years and 11 months. The questions worth answering in advance are whether you meet the requirements, when exactly to apply, and whether the exemption from the employment requirement is available to you.
