An American's route into North Sea diving

The question, as it arrived

A reader wrote in: an American citizen, no diving experience yet, planning to train at a Norwegian commercial diving school on a student visa and then work the North Sea on a work visa, with saturation as the eventual goal. His own words were that it "seems doable but I'm not sure it's necessarily practical", and that his friends in the trade are all US-based and have no idea.

It is a better-informed plan than most, and two of its three assumptions hold up. The one that does not is the one everybody gets wrong, and the hurdle he is worried about is not the hurdle that will stop him. Here is each piece, checked against the primary documents.

Your certificate is the easy part

The fear behind this plan is usually that you train in one country and the market you want will not recognise the paper. For Norway into the UK, that fear is unfounded, and you can check it yourself in one document.

The UK's Diving at Work Regulations 1997 require an approved qualification for the work you are doing, and the Health and Safety Executive publishes the list of what counts. In the edition issued on 1 January 2025, Schedule 1 — the offshore schedule — lists the Norwegian Dykkersertifikat Klasse I – Overflateorientert dykker as valid for SCUBA, surface supplied and surface supplied top-up work. The same schedule lists, for closed bell, the "diver certificate issued by the Petroleum Safety Authority/HAVTIL, Norway".

So a Norwegian Class 1 is not a workaround or a second-class entry. It sits on the HSE list alongside the British qualifications, and a Norwegian bell ticket is accepted for closed bell work in UK waters. Two conditions attach, and they are in the same document: a non-UK qualification must be current and renewed as the issuing authority requires, and any restriction printed on the certificate must be complied with strictly.

If you want the full comparison of what each scheme covers and which markets accept it, that is our certifications page.

No school takes you to saturation — not even the Norwegian one

This is the assumption that breaks. The plan was "school, then sat". No school in the world works that way, and the Norwegian school's own admissions page is the cleanest proof of it.

Its Class 2 saturation course requires, before you can enrol: an IMCA-recognised commercial diver Class 1 certificate with at least one year of experience, a minimum of 100 commercial dives, a minimum of 100 hours of bottom time on commercial dives, and a medical certificate from an approved diving physician. Those are not formalities to be waived for a motivated candidate. They are the gate, and they are roughly the same gate in every regime: a year holding a 50-metre qualification and a hundred logged dives over a hundred hours on the bottom.

Which means the sequence is not school then sat. It is school, then one to three years of working air diving wherever you can get hired, then the bell course. Our own reading of the realistic timeline from a standing start is four to six years, and the closed bell courses themselves — £36,000 in the UK, AUD $45,000 in Australia — were sold out into 2027 when we last checked. The bottleneck is downstream of everything you are currently planning.

One more thing to confirm before you build anything on it: when we verified the Norwegian school's entry in our directory, its saturation course was paused. Ask them directly whether it is running before you treat it as a destination.

The first real hurdle is the study permit, not the work visa

The Class 1 course at the Norwegian school runs 16 weeks and costs NOK 72,000, rising to NOK 76,000 from November 2027. It issues a Havtil certificate for surface-oriented diving to 50 metres offshore, a Labour Inspection Authority class B certificate for inland work to 50 metres, and an IDSA Level 3.

Sixteen weeks is the problem. A US passport gets you 90 days in any 180 in the Schengen area, and 16 weeks is about 112 days. You cannot do this course as a visitor. You need a Norwegian residence permit for studies, and the Directorate of Immigration's conditions for one are specific: for a vocational school, the school must appear on NOKUT's list of approved vocational schools, the programme cannot be online, and you must document funds of NOK 166,859 for a year — about NOK 15,169 a month, or NOK 75,845 for an autumn semester alone. The permit lets you work 20 hours a week alongside study, and full-time in holidays, but not self-employed.

Here is the flag. The school's admission requirements page lists age, swimming ability, a 45-second breath hold and a diving medical. It says nothing about nationality, residency, language of instruction, a Norwegian personal number or a permit, and its "about" page says nothing about foreign students either. That is not evidence that it cannot be done. It is evidence that you must get a straight answer in writing — specifically, whether the school is on NOKUT's approved list and has placed non-EEA students on study permits before — before you pay a deposit on a flight or a course.

For contrast, the UK is lighter on this exact point: a standard visitor may study for courses of up to six months, and a ten-week dive course fits inside that. The accreditation condition on the institution still needs checking, but the structural gap between "needs a residence permit" and "fits in a visitor stay" is the kind of difference that decides plans.

The work-permission surprise: outside twelve miles, the UK does not ask

Now the part that is better news than the reader expected. He was planning around a North Sea work visa. For much of the work, that is not the mechanism.

The UK Immigration Rules bite in UK waters — the territorial sea, within 12 nautical miles of the coast. Beyond that, on the UK continental shelf, a non-British and non-Irish citizen does not need a UK visa to work on a fixed structure such as a platform. What you still need is permission for any shore leave in the UK, which for an American means an ETA or the appropriate permission for the way you are travelling, and compliance with the Offshore Worker Notification regime that has applied since 12 April 2023: the Home Office must be told the date you first arrive in UK waters and the day you leave, no earlier than the event and no later than ten working days after. If you are sponsored, the sponsor makes those notifications.

Where the work does touch UK waters or the shore, the sponsored routes are the answer — Skilled Worker, or Senior or Specialist Worker — and both require an employer with a sponsor licence. There is a seafarer visitor provision for vessels on genuine international routes and a concession for offshore well boat workers; the Offshore Wind Workers Concession was withdrawn on 23 May 2023 and those workers now come under the ordinary rules.

The practical reading: your immigration position is not a thing you fix in advance and then go job-hunting with. It is a thing your employer's mobility people work out once they want you, and it depends on the vessel, the flag and where the work sits relative to twelve miles.

Norway is the harder door

If the plan was to train in Norway and then work Norway, that is the tighter of the two markets for a non-EEA national. Norway has no short-term work permit. Hands-on work needs either a sponsored work and residence permit or the narrow "technical exemption", which has to be notified to the relevant police district before travel and which each district decides at its own discretion; leaning on it repeatedly for ongoing work risks fines for both the worker and the sponsor. For a platform permanently fixed to the sea floor on the Norwegian shelf, the Immigration Act applies to every foreign employee travelling there. A floating unit in transit is treated differently, and the position shifts again once it goes into production or attaches to a fixed installation.

And the sponsored skilled worker route has a qualification threshold of its own. A 16-week vocational course is a thin basis for it. If Norway specifically is the goal, that question deserves an immigration adviser before a deposit, not after.

The real gate is nobody wanting to hire a brand-new diver with a US passport

Here is the honest answer to "doable but is it practical". Neither the certificate nor the paperwork is what will stop you. What stops people is the entry-level hiring market.

A European contractor filling a bottom-rung air diving slot is choosing among people who arrive with no paperwork attached at all, because they are EEA nationals with an automatic right to work. You would be asking that contractor to take on friction at precisely the moment you have the least to offer in return — no logged dives, no references in the market, no track record anyone there can check. Later, with a year offshore and a hundred dives behind you, the same friction gets absorbed without comment, because the company has a reason to absorb it.

That asymmetry, not the visa rules, is what makes the "qualify abroad first" version of this plan expensive. You would pay to train in Europe and then compete at the hardest possible moment with the weakest possible hand.

What the four routes cost

Two things jump out of that table for an American. The Norwegian course is the cheapest of the four and among the shortest. And the US route, the one that needs no visa at all, is by some distance the most expensive and the longest.

What I would actually do

Separate the two decisions that this plan bundles together: where you qualify, and where you work. They do not have to be the same place, and the certificate evidence above is exactly why.

If the North Sea is genuinely the destination, the UK is the strongest first move. It is cheaper and faster than the US, it puts you natively inside the HSE system rather than adjacent to it, a ten-week course fits inside a six-month visitor stay, and you spend those ten weeks in the market where you want to be known. Qualify there, then take whatever air diving work you can get hired for anywhere — inland, inshore, the Gulf of Mexico, wherever answers — because what you are buying in those first years is not the location, it is the hundred dives and the hundred hours. Then book the bell course, and cross back to the North Sea with experience, at the point where a company has a reason to solve your paperwork for you.

If the goal is less fixed than that, the US route is slower and dearer but removes the immigration variable entirely, and the Gulf hires beginners at volume. Many American sat divers got there that way.

The one version I would not do is the one that was on the table: pay Norwegian prices for a Norwegian permit in order to arrive, unqualified by experience, in the hardest entry-level market in the world for a non-EEA passport, hoping to reach a saturation course that requires a year of work you have not done yet.
