Stamp 1 Ireland 2026: Work Permit Rules & Path to Stamp 4

Stamp 1 is Ireland’s employment-permit stamp: it lets you work — or in limited cases run a business — for the employer named on your permit, and nothing beyond that. ISD’s condition is blunt: you must not start a job unless you or your employer holds an employment permit for you, or an ISD letter says you don’t need one. The upside is that it counts: Stamp 1 is reckonable residence toward citizenship, and it’s the standard route to the far freer Stamp 4.

The 60-second version:

1. Stamp 1 requires a valid employment permit (Critical Skills, General Employment, Intra-Company Transfer, etc.) or a letter from ISD allowing you to work without one.
2. It’s tied to your employer. Changing job means a new permit, not just a new payslip.
3. Registration is usually valid for 12 months, then renewable. The fee is €300.
4. You may qualify for Stamp 4 after 21 months on a Critical Skills permit, or 57 months on a General Employment permit — earlier than the “2 years / 5 years” you’ll often see quoted.

What Stamp 1 lets you do — and what it doesn’t

ISD’s summary of the Stamp 1 conditions is worth reading literally, because the limits are the whole point of the stamp:

• Work on a permit. You must not start a job or enter employment unless you or your employer has obtained an employment permit for you — or your letter of permission clearly states you don’t need one.
• Business only if specified. If you don’t hold an employment permit, you must not engage in any business, trade or profession unless it’s specified in a letter of permission from ISD. A standard permit-based Stamp 1 does not let you freelance or set up a company on the side.
• Renew before expiry. If you want to stay past the expiry date on your IRP card, you must apply to renew your permission and registration before it expires.

And the part that makes the years count: Stamp 1 is reckonable as residence when applying for citizenship by naturalisation.

Who gets Stamp 1

You’re registered on Stamp 1 if you’re in Ireland to work on one of these bases:

• An employment permit granted by the Department of Enterprise, Trade and Employment — most commonly a Critical Skills Employment Permit or a General Employment Permit, but also Intra-Company Transfer, reactivation and other permit types.
• A research Hosting Agreement granted by the Department of Further and Higher Education, Research, Innovation and Science.
• A letter from the Minister for Justice granting you permission to work in Ireland for more than 90 days (the letter sets out exactly what you may do, including whether you can be self-employed).
• A Working Holiday Authorisation — though ISD notes this permission is not renewable.

In every case the registration reflects the underlying permission. Stamp 1 doesn’t stand alone; it’s the residence side of a work permission granted by another department.

From Stamp 1 to Stamp 4: the real timelines

This is the question most people on Stamp 1 are actually asking, and ISD’s required-documents page gives exact figures — which are shorter than the round numbers most guides repeat:

Your permit	You may be eligible for Stamp 4 after
Critical Skills Employment Permit	21 months from commencement of employment
General Employment Permit	57 months from commencement of employment
Researcher on a Hosting Agreement	21 months from commencement of employment

Read “may be eligible” carefully — these are eligibility thresholds with their own conditions, not automatic grants. But the practical takeaway is real: a Critical Skills holder can apply for Stamp 4 at 21 months, not 24, and a General Employment holder at 57 months, not 60. Applying at the earliest eligible point matters, because Stamp 4 removes the employer lock entirely.

Your Stamp 1 time still counts as reckonable residence for citizenship, so moving to Stamp 4 doesn’t reset your clock — see the Critical Skills permit guide for the permit side, and the full Stamp 4 guide for the routes in and the fee exemptions.

Documents for Stamp 1

ISD’s required-documents list differs between a first registration and a renewal. For a permit-based Stamp 1:

First-time registration	Renewal
Biometric page of your current valid passport	Biometric page of your current valid passport
Your employment permit	Front and back of your current IRP card
Proof of new employment (e.g. an employer letter)	Your employment permit
—	Proof of current employment (e.g. a payslip dated within the last 3 months)

Bring originals — ISD does not complete registrations without the required documents. The exact list can vary with your permit type and circumstances, so check the current required-documents page before your appointment.

Stamp 1 vs Stamp 1G vs Stamp 4

These get confused constantly because the labels look alike, but they’re three different permissions:

	Stamp 1	Stamp 1G	Stamp 4
Who it’s for	Employment-permit holders	Graduates job-hunting, or spouse/de-facto partner of certain permit holders	People past the qualifying period, family of Irish/EU citizens, refugees
Employment permit needed?	Yes	No	No
Change employer	New permit required	Freely (within conditions)	Freely
Run a business	Only if specified	Not on the graduate route	Yes
Counts toward citizenship	Yes	Conditionally	Yes

If you finished an Irish degree and want to look for work, you want Stamp 1G (the Third Level Graduate Programme), not Stamp 1. Stamp 1G is a distinct enough topic — with its own graduate and spouse routes — that it’s worth its own guide; for now the immigration stamps overview covers where it sits.

Renewing Stamp 1

Renewals for all counties now run through the ISD online portal. Apply before the expiry date on your IRP card, not after — letting a permission lapse puts both your residence and your reckonable residence for citizenship at risk. Your renewal has to show you’re still validly employed on a permit, which is why ISD asks for a recent payslip alongside the permit itself.

Where Stamp 1 leads

Stamp 1 is a staging post, not a destination. It ties you to one employer while the permit runs, but every month counts toward citizenship, and it opens onto Stamp 4 — full work rights with no permit — after 21 months (Critical Skills) or 57 months (General Employment). If you’re mapping the whole path, read the Stamp 4 guide next, or the full stamp reference if you’re not certain which stamp you’re on.
