Lead time, and why early matters

The most common thing we hear is "I did not realise it took that long". It is rarely the official processing queue that catches people out. It is everything that has to happen before the file can even be submitted, all of which depends on other people's calendars rather than yours.

This guide is about where the time actually goes. How much lead time a particular route needs is destination-specific and comes from a verified record, not from an estimate.

The calendar is mostly other people's

Work backwards from a departure date and the chain looks like this.

Getting a doctor's appointment. Not the appointment itself — the wait for it. This is frequently the longest single item, and it is entirely outside everyone's control.

The doctor producing the document. Even when the draft is prepared for them, a letter has to be reviewed, signed, stamped and collected. Practices have their own turnaround.

Certification, if the route requires it. A certified translation takes days. A notary appointment takes days. An apostille takes longer still, and it can only start once the document underneath it exists. These stack in sequence rather than running in parallel — see translation, notarisation and apostille.

Assembling and submitting. Fast, when everything above is complete.

The authority's own processing. The part everyone thinks about, and often not the largest part.

Delivery of the answer. Where the reply travels by post, add the post. If it travels to an address rather than to an inbox, add the risk of it going to the wrong one.

Add those together and the front half of the chain usually outweighs the back half.

The re-do risk

The real reason to start early is not the sum of the steps. It is that a correction restarts a segment.

If a document comes back missing a field, you do not lose a day — you lose the doctor's turnaround again, and if certification had already begun, you lose that too and pay for it twice. Every step you complete late is a step you cannot afford to get wrong. Starting early buys you the ability to be wrong once cheaply, which is worth more than the days themselves.

What early buys you

Choice. With time in hand, a route that is slower but more certain is available. With a fortnight left, you may be limited to whichever route is fastest, whether or not it is the one you would have chosen.

Correction. Room to fix a missing registration number without the fix costing you the trip.

Verification. Where our record has an open point, time to close it before you are committed rather than during.

Alternatives. If a route turns out to be blocked, there is still time to consider what else is possible — including, occasionally, changing the plan.

What late still leaves open

Late is not the same as hopeless, and we would rather look than tell you not to bother. What changes is the shape of the conversation. Some routes fall away because their minimum lead time simply exceeds the days available. Expedited handling exists in places and is never something to rely on. And there is always the option of travelling on documentation alone where a route allows it, which is a different risk profile that should be chosen knowingly rather than by default.

What we will not do is tell you a file will arrive in time. Nobody can promise that, and a promise like that is the clearest sign that somebody is selling you something they do not control.

Fixed points to build around

Two dates anchor everything. The date the trip is fixed — that is when work can begin, not when you get round to it. And the date a document expires — some documents have a shelf life, so producing them too early is its own mistake. The gap between those two is your actual working window, and it is usually narrower than the gap to departure.

Practical sequence

1. Fix the destination and dates.
2. Establish immediately whether a route is involved at all. This is a

conversation, not a project, and it is free.

1. If it is, book the doctor's appointment first — it is the longest queue.
2. Prepare the paperwork so the appointment is a signature rather than a

drafting session.

1. Start certification only once the underlying document is final.
2. Submit, and track.

What we do

We tell you what the realistic window looks like for your route at the start, in the free consult, before any payment. We move without delay on our side, and we flag it when the runway gets short so that you can make a decision while you still have one to make — see how it works.

If your dates are set, the cheapest thing you can do today is ask. The answer takes minutes and it is the difference between choosing your route and being assigned one by the calendar.
