Medical Inadmissibility: When a Family Member's Condition Blocks the Visa

Medical inadmissibility is a refusal ground that applies to the whole family unit, so a dependant's health condition can end an application even when the principal applicant is flawless on points, English, experience and funds. In Canada, Australia and New Zealand, the immigration medical examination assesses every family member included in the application, and in Canada's case it also assesses certain family members who are not coming with you. If any one person fails the health requirement, the refusal usually lands on the whole application and everyone in it.

The test in these three countries is mostly a cost test, called excessive demand in Canada and the significant cost threshold in Australia. Immigration doctors estimate the likely cost of a person's health and, in some systems, social services over a defined future period, and compare that estimate against a published threshold. Conditions that commonly come up include intellectual disability, autism with high support needs, cerebral palsy, end-stage renal disease requiring dialysis, some cancers, congenital heart conditions and severe developmental delay in a child. A separate and much narrower category refuses on public health or public safety grounds, for example active untreated tuberculosis.

Two things matter more than the diagnosis. First, whether the destination runs a cost test at all: the United Kingdom, Germany, Ireland and most of the EU do not run an excessive demand style assessment for skilled routes. Second, whether the subclass you apply under allows a waiver or a mitigation submission. Because those two levers differ so sharply between countries, destination choice is usually the strongest thing a family in this position can change.

This article is general information. These cases turn on the specific diagnosis, subclass and medical evidence, so a licensed or registered immigration adviser in the destination country should confirm your case before you spend money.

Who this affects

You should read this carefully if any of the following describe your household:

• A child with a diagnosis that implies ongoing therapy, special education support, or lifelong assistance.
• A spouse or child with a condition requiring recurring high-cost treatment, for example dialysis, biologic drugs, transplant follow-up or long-term specialist care.
• A dependent parent or grandparent you plan to include in the application, where age plus a chronic condition raises the projected cost.
• A family member who will stay behind, if you are applying to Canada, because non-accompanying family members are generally still required to be examined.
• Anyone in the household with a communicable disease that a destination screens for as a public health matter.

If nobody in the household has a significant condition, this is unlikely to be your obstacle, and our guide to migrating with a pre-existing health condition covers the more ordinary case of managing a chronic condition through insurance and health system access.

Why the whole family unit is assessed

Skilled migration is granted to a household, so the assessment covers the household. When you list a spouse and children as dependants, each of them becomes an applicant for admissibility purposes. Each sits the medical examination with a panel physician approved by the destination, and each can independently trigger a refusal.

Canada extends this further than most. IRCC generally requires family members who are not accompanying you to be examined as well, on the logic that they could later be sponsored. There are exclusions, and these rules have changed over time, so read the current IRCC guidance on who must undergo the immigration medical examination before assuming a family member back home is out of scope.

The practical consequence is worth stating plainly. A nurse with a strong score, a valid registration and a job offer can be refused because of a four-year-old's diagnosis. The application is one object, and it either clears admissibility for everyone or it does not clear at all.

What the excessive demand cost test measures

Where a cost test exists, the mechanics look broadly similar even though the numbers and the wording differ.

A panel physician conducts the examination and sends the results to a medical officer employed by the immigration authority. The opinion is formed by the medical officer, and the panel physician only supplies the examination findings. That opinion estimates the likely publicly funded health costs, and in some systems social service costs such as special education, over a defined assessment period, then compares the estimate against a published threshold. If the estimate exceeds the threshold, the application heads toward refusal unless it is answered.

Several features of this design matter for planning:

• It is prospective. The officer estimates future cost, so a condition that has been stable and cheap to manage for a decade can still produce a high projected figure if the standard care pathway in the destination is expensive.
• It measures cost falling on the public purse. Treatment you would fund privately is often still counted, provided the service would ordinarily be publicly funded in the destination.
• The assessment period is defined and finite. Systems run the estimate over a set number of years, with a longer period where care is expected to be needed indefinitely. Canada and Australia each publish the period they use, and the period materially changes the total, so read it off the authority's own page alongside the threshold figure.
• The threshold is reindexed. Every cost threshold discussed here is republished periodically, so a number from a forum post two years old is very likely wrong.

Treat every figure below as a planning range and reconfirm it on the issuing authority's own page before you budget, apply, or conclude that you are over or under the line.

What the thresholds are, as published

Two figures get asked about constantly, so here is how to handle them honestly.

Canada. IRCC publishes an excessive demand cost threshold as an annual figure, per year over the assessment period, and reindexes it. Since the 2018 policy change that tripled the threshold and removed most special education and social service costs from the calculation, the published figure has sat in the region of the mid to high CA$20,000s per year and has moved upward at each reindexation. Do not plan against the number in this sentence: open IRCC's medical inadmissibility page, read the figure published there today with its date, and use that.

Australia. The Department of Home Affairs applies a significant cost threshold to the health requirement, published as a total over the relevant assessment period. It has been published in the AU$80,000s in recent years and is reviewed periodically. Confirm the current figure and the current assessment period on the Department's health requirement page.

New Zealand's instructions describe conditions likely to impose significant costs or demands on health or special education services, and Immigration New Zealand publishes the condition list and assessment approach in its operational manual. Read the current instructions directly.

Conditions assessed on public health or public safety grounds

The cost test is the common problem, and it is worth separating it from two narrower grounds that work differently.

Public health. This covers communicable disease, in practice mainly active tuberculosis. Screening is standard, and this ground is usually curable in the procedural sense: complete treatment, produce clear results, and the ground falls away. It typically delays an application by a matter of months. The UK's tuberculosis certificate requirement for applicants from listed countries is a screening step of this type, and it sits outside any cost assessment.

Public safety. This covers conditions where the person is assessed as posing a danger to others, a narrow category assessed on individual evidence. It works on individual behavioural evidence, and a psychiatric diagnosis on its own falls outside it.

HIV status deserves a note because the advice circulating online is often a decade out of date. Canada, Australia, New Zealand, the UK and the EU do not refuse residence on HIV status as such, although in a cost-testing country the treatment cost can still be assessed under the excessive demand rules. Several Gulf states do screen for HIV and hepatitis at the residence permit stage and refuse residence on that basis, and the screening applies to sponsored dependants too. If a Gulf move is on your list, verify the current position with that country's health authority before accepting an offer, because a failed medical there ends the residence permit regardless of the employment contract.

Mitigation plans and waivers

When an adverse medical opinion is formed, most systems give you a chance to answer before refusing. What that chance is called, and how much it can achieve, differs.

Canada: the procedural fairness letter. If an officer forms the opinion that a family member would cause excessive demand, IRCC generally issues a procedural fairness letter setting out the assessment, the projected costs and the reasoning, and gives you a defined period to respond. A response usually attacks two things: the medical facts, and the cost projection. Specialist evidence can show that the assumed care pathway is wrong or that the condition is better controlled than the file suggests. The cost side can show that specific line items would not in fact be publicly funded, or have been double counted. Some responses also declare an ability and intent to privately fund what can lawfully be privately funded, with evidence the money exists. Whether that is accepted depends on the cost involved, since a service you cannot lawfully opt out of publicly funding cannot be mitigated this way.

Australia: the health waiver. Australia's waiver is set by the visa subclass. Some subclasses allow it and some do not, and that is decided by the visa you applied for. Where a waiver is available, the decision weighs the cost against factors such as compassionate circumstances and the applicant's contribution. Two otherwise similar skilled routes can differ on this single point, so check the subclass page on the Department of Home Affairs site and have a registered migration agent confirm it before you commit.

New Zealand: the medical waiver. Immigration New Zealand allows a medical waiver for some visa categories, assessed against published factors. As in Australia, the category determines whether the door exists at all.

A realistic note on all three. A well-prepared response takes time, costs money in specialist reports, and has no predictable outcome. Families who succeed generally started collecting evidence before the medical examination. Families who fail often responded with argument and no new medical evidence. If a refusal has already happened, our guide to what to do if your visa is refused covers appeal, judicial review and reapplication.

What you need before you start

Assemble this before you pay for a skills assessment, a language test or an application fee, because it changes which country you should even apply to.

• A written diagnosis and current clinical summary from the treating specialist, in English or professionally translated, with dates.
• The actual care plan, naming medications and doses, therapy frequency, specialist review intervals, equipment and any surgical plan.
• A prognosis statement covering expected progression over the next five to ten years, since the assessment is forward looking.
• A record of what the care has actually cost over the last two or three years, with receipts or insurer statements.
• Education support documentation for a child: any individualised education plan, hours of aide support and therapy funded through school.
• Evidence of funds, if you intend to argue private funding of any part of the care.
• A shortlist of destinations with each one's health requirement noted.

Build this file early, because a good adviser can tell you from it whether you are near a threshold before you spend anything. Guessing from a diagnosis name alone produces both false panic and false comfort.

Destination choice is the real lever

For most families in this position, the largest single improvement available is changing where they apply. The condition is fixed, the points score moves slowly, and the threshold is set by a government. The country is the variable you control. Three patterns are worth understanding.

Cost-testing countries versus non-cost-testing countries. Canada, Australia and New Zealand can refuse on projected public cost. The UK, Germany, Ireland and most of the EU do not run an equivalent test for skilled work routes. For a household with a high-cost condition, that difference is decisive in a way no amount of points optimisation can match. The trade-off is that UK, German and Irish routes lean on employer sponsorship and salary, so you need a job offer to make them work. Our guides to the UK Skilled Worker visa and to skilled visa routes without a job offer set out what each demands.

Waiver-available subclasses versus waiver-unavailable ones. Within Australia, the choice of subclass changes whether you have any second chance at all. A family that would be borderline on the cost test should treat waiver availability as a first-order selection criterion, alongside occupation eligibility and state nomination.

Temporary versus permanent. Health requirements bite hardest at the permanent residence stage, since that is where a country takes on lifetime cost. Some families move first on a temporary employer-sponsored visa, establish employment and a treatment record, and address permanent residence later. This can work and it carries genuine risk, because the later application faces the same assessment with the same family member. Take that path with a plan for what happens if permanent residence is refused in year four.

Healthcare quality and admissibility can pull in opposite directions. The countries with the most generous public systems for a high-needs child are often the most careful about who they admit into those systems. A destination that admits you readily may deliver worse care for the specific condition. Weighing those two against each other is exactly the judgement a roadmap is for.

What it costs

Process costs for the medical side. Treat every figure as a planning range and confirm the current fee with the issuing body.

The medical examination itself is a small cost. The expensive part is the response, and it arrives after you have already paid for everything else. That asymmetry is the argument for checking your exposure at the start.

How long it takes

The medical examination is usually completed within days, and for the large majority of applicants nothing further happens.

Where a file is referred to a medical officer for a fuller assessment, expect the application to sit for additional weeks or months on top of the authority's published processing time. If a procedural fairness letter or a request for further information is issued, you are typically given a window measured in weeks to respond. Gathering specialist reports inside that window is the usual pressure point, because consultant appointments and written reports rarely arrive on demand. If you already know a condition is significant, ask your specialists for the letters before the request exists.

If the response fails and you move to appeal or judicial review, add many months to more than a year depending on the forum. Confirm current processing and appeal timelines with the authority handling your case.

When this does not work

The section most articles on this subject avoid. Some cases do not have a good route, and knowing that early saves years and a lot of money.

• A high-cost, lifelong, publicly funded condition in a cost-testing country, on a subclass with no waiver. If the projected cost sits well above the threshold and there is no waiver door, that route is closed. The answer is a different country or a different subclass. A better-written letter will not move it.
• A Gulf move where a screened communicable disease is present in the household. Fitness screening at the residence permit stage is administrative and largely binary, and an employment contract does not override it.
• A borderline condition where the family cannot fund a proper response. A weak response to a procedural fairness letter is close to no response. If specialist reports are unaffordable, redirect the money toward a destination that does not run the test.
• Non-disclosure as a strategy. Concealing a diagnosis is the worst option here. Immigration medicals are designed to find significant conditions, and a misrepresentation finding carries a multi-year bar in Canada and Australia. Disclose, then argue.

Said plainly: for some families Canada and Australia are closed, and continuing to push at them is the expensive mistake. A UK or Irish employer-sponsored route, a German skilled worker route, or a longer runway on temporary status will serve you better. That redirection is worth more than any optimisation of a route you cannot pass.

Common mistakes

1. Assuming the diagnosis decides it. The assessment is a cost projection, and two people with the same diagnosis can land on opposite sides of a threshold.
2. Reading a threshold figure from a forum. Every threshold here is reindexed. Use the authority's own page and note the date on it.
3. Choosing a subclass before checking waiver availability. In Australia this can remove your only second chance, and it is decided before you apply.
4. Forgetting non-accompanying family members. Canada's examination requirement can extend to family members staying behind. Check the current rule before you assume otherwise.
5. Responding to a fairness letter with argument and no evidence. New medical evidence and a costed plan move these cases. Sympathy on its own does not.
6. Not disclosing. A misrepresentation finding is worse than an inadmissibility finding, and it follows you across applications.
7. Ignoring the insurance and care question. Admissibility gets you in. Whether the condition is well treated once you arrive is a separate question, covered in our family checklist for moving abroad.
8. Paying an unregistered agent who promises a medical waiver. No one can guarantee an outcome on a medical inadmissibility case.

Agents, promises and how to check

This topic attracts bad actors, because families facing a refusal are frightened and motivated. Nobody can guarantee a health waiver, a favourable medical opinion or any specific outcome, so treat guaranteed-visa language as a reason to walk away. Never pay into a personal bank account, and never pay a fee to be introduced to a job offer.

Check registration before you pay anything. Canadian consultants are regulated by the College of Immigration and Citizenship Consultants and Canadian lawyers by their provincial law society; Australian migration agents appear on the Office of the Migration Agents Registration Authority register; UK advisers are regulated by the Immigration Advice Authority or the legal regulators; New Zealand advisers are licensed by the Immigration Advisers Authority. Each publishes a searchable public register, so search the person's own name on the regulator's register itself.

Be wary of anyone offering to obtain medical reports from a doctor you have never met. A purchased report converts a difficult case into a misrepresentation case. Our guide to avoiding immigration scams covers the wider pattern of upfront-fee and guaranteed-outcome offers.

Frequently Asked Questions

Can one family member's health condition really cause the whole family to be refused?

Yes. In Canada, Australia and New Zealand, admissibility is assessed for every person included in the application, and an adverse finding against one dependant generally results in refusal of the application as a whole. The strength of the principal applicant does not offset a dependant's inadmissibility finding.

What is the current excessive demand cost threshold in Canada?

IRCC publishes it as an annual figure, per year over the assessment period, and reindexes it, which is why no article should be treated as the source. Since the 2018 change it has been published in the region of the mid to high CA$20,000s per year. Open IRCC's medical inadmissibility page, read the figure with its stated date, and use that.

Does Australia allow a health waiver for skilled visas?

A health waiver exists for some visa subclasses and not for others, and the subclass you applied under determines availability, independently of the condition or the circumstances. Because of that, waiver availability should be checked on the Department of Home Affairs subclass page before you commit to a route, and confirmed by a registered migration agent.

Are children with autism automatically refused?

No. There is no automatic refusal for any diagnosis in these systems. What is assessed is the projected cost of the support the person is likely to need over the assessment period, so support needs, therapy intensity and educational assistance drive the outcome. Canada's 2018 change also removed most special education costs from the excessive demand calculation. Confirm the current calculation rules with IRCC.

Which countries do not run an excessive demand test?

The United Kingdom, Germany, Ireland and most of the EU do not apply an excessive demand style cost assessment to skilled work routes. The UK requires a tuberculosis certificate from applicants in listed countries and charges the Immigration Health Surcharge; Germany and Ireland turn on health insurance coverage. Those routes generally require employer sponsorship, so you trade a health assessment for a job offer requirement. Verify current requirements with UKVI, the German missions and the Irish immigration service.

Does private health insurance solve the problem?

Not by itself in a cost-testing country. The assessment measures cost falling on public health and, where applicable, social services, and some of those costs cannot be opted out of by buying insurance. Private funding evidence can form part of a mitigation response for certain cost lines. In non-cost-testing countries such as Germany and Ireland, insurance coverage is the operative requirement and is a genuine solution.

What to do next

If someone in your household has a significant condition, do three things in order. Build the medical file described above, including the prognosis and the real cost history. Establish which of your candidate destinations run a cost test and which do not. Then get a licensed adviser in the one or two countries that survive that filter to read the actual file before you spend money on assessments, tests and fees.

The free free eligibility assessment takes your occupation, your family composition and your constraints and matches them against routes, including the non-cost-testing destinations a household in this position should be weighing alongside the obvious ones. If the honest answer for your family is that Canada or Australia is closed on your current subclass and diagnosis, it is better to learn that before the application fee than after the procedural fairness letter.

If you want the whole sequence written out for your household, naming the destinations that fit, the subclasses where a waiver exists, the documents to gather and the order to do things in, that is what NextMigrate's personal migration roadmap is for: $499, down from $999, started with a $99 deposit with the balance settled afterwards. It is general planning work, it does not replace a licensed adviser on the medical submission itself, and it will tell you where to point that adviser.
