An intern exemption is not a cheap employee

In plain termsThe student or trainee internship limb can skip a work permit (WP). A labour contract does not. Compulsory health insurance (BHYT) keys off contract length, not the word “intern” on a badge.

Start here — three checks

True intern limb? yes
Otherwise permit default. yes
BHYT if it is really employment ≥ 12 months.

Badge vs contract

Arrangement	Labour read	If you relabel
Enrolled student / trainee internship (including listed seafarer training)	Permit-exempt on that limb.	You skip school confirmation and call it an intern anyway.
Full-time work, salary, indefinite-looking duties	Employee. Permit required. BHYT if the contract is ≥12 months.	Working without a permit: forced exit or deportation.
“Unpaid intern” doing production work	Unpaid does not by itself become the volunteer-treaty limb.	You invent a third category the decree does not sell.
Expert or technician title on a short secondment	Different exemption or permit path — not this intern page.	You copy intern logic onto an expert file.

Common wrong movesCost comparison is not a legal form.

Using intern status to dodge BHYT on an 18-month labour contract.
Skipping the employer need-justification because “it’s only a trainee.”
Putting the intern on a tourist stamp.

If the person is already workingName the real form. Then file that form.

If it is employment, stop and open the permit stack.
If it is a real intern limb, keep the school/training confirmation in the file.

Common questions

Can we hire a foreign intern without a work permit?

A student or trainee internship — including listed seafarer training — can be permit-exempt. A paid role that is actually employment is not that limb. Foreign workers generally need a permit.

If the internship lasts 18 months, is BHYT compulsory?

Compulsory BHYT for foreign employees keys to a definite-term labour contract of at least 12 months. An internship that is not that contract does not automatically inherit the BHYT gate — and a disguised employment contract does.

What if they are just ‘helping for three months’?

Working without a permit where one is required can mean forced exit or deportation. Three months of labour is not a synonym for the student-intern exemption.
