ISD Portal Guide: How to Submit Your Stamp 4 Application Online

If you have reached the Stamp 4 eligibility threshold — 21 months on a Critical Skills Employment Permit or 57 months on a General Employment Permit — the application itself is submitted entirely online through the ISD portal at irishimmigration.ie. There is no in-person appointment, no mailing of original documents, and no queue at Burgh Quay for this stage.

What there is, however, is a portal that many applicants find confusing on first use, with file size limits that reject most documents in their native format and status labels that do not mean what they appear to mean. This guide walks through the submission process step by step, covering the practical points the official guidance glosses over.

Before You Start: Check Your Eligibility Date

Submit your Stamp 4 application after your eligibility threshold date, not before. Submitting even one week before you have completed 21 months (CSEP) or 57 months (GEP) will result in an automatic refusal for failing to meet the qualifying period.

Calculate your eligibility date from your Revenue employment start date — the date your employer first submitted payroll records for you, as shown on your Employment Detail Summary. This is not necessarily the same as your employment permit start date or your IRP registration date. The April 2024 ISD administrative update confirmed that Revenue's records determine the start point.

If you are within a few months of eligibility but not yet there, use the time to prepare your document pack. A well-prepared submission moves faster through the queue.

Creating Your ISD Account

If you have previously renewed your IRP card through the online portal, you already have an ISD account. Log in with those credentials.

If this is your first time using the portal — which it will be for most first-time Stamp 4 applicants who previously registered in person — you need to create an account at irishimmigration.ie. You will need:

• A valid email address (this becomes your login)
• Your IRP number (on the front of your current IRP card)
• Your date of birth

After creating the account, allow 24 hours for your IRP records to link before attempting to submit an application. Some applicants report that submitting immediately after account creation results in a "no active permission found" error.

Selecting the Correct Application Category

This is where many applicants make their first mistake. The ISD portal has multiple application categories, and the category you select determines the form fields, the document requirements, and which caseworker team processes your application.

For a Stamp 4 upgrade from a CSEP:

• Select "Change of Status" or "Stamp 4 Upgrade — Employment Permit" depending on how the portal labels it in your account. The exact label has changed through several portal updates.

For a Stamp 4 renewal (you already have Stamp 4 and need to renew the card):

• Select "Renewal"

For a spouse/partner route:

• Select the appropriate family-based category, which routes you to a different caseworker team with different document requirements.

If you are unsure which category applies to your situation, review the ISD guidance page on Stamp 4 upgrades (irishimmigration.ie/registering-your-immigration-permission/how-to-renew-your-current-permission/information-on-stamp-4-upgrades/) before submitting. Selecting the wrong category does not invalidate your application irretrievably, but it does cause delays as caseworkers transfer it to the correct team.

Preparing Your Documents: The 1MB Limit Problem

The ISD portal enforces a 1MB maximum file size per uploaded document. This is the single most common cause of upload failures.

Most documents in their standard format exceed this limit:

• A multi-page passport scan: typically 3 to 8MB
• An employer letter scanned at normal quality: typically 1.5 to 4MB
• A Revenue EDS downloaded as PDF: typically 300KB to 1MB (often fine, but borderline)
• A bank statement downloaded from online banking: varies, often 1 to 3MB

Before uploading, compress every file. Reliable methods:

For PDFs: Use a browser-based PDF compressor (ilovepdf.com, smallpdf.com) or Adobe Acrobat's "Reduce File Size" option. Target under 800KB per file to give yourself margin.

For scanned documents: When scanning, select 150 DPI rather than 300 DPI. Black-and-white scanning instead of color reduces file size significantly for text documents. For documents that need to show color (passport bio-data page, IRP card), 150 DPI color is usually sufficient.

For smartphone photos: Most phone cameras produce 3 to 6MB JPEGs. Use a compression app or convert to PDF through a scanner app that lets you control output quality.

The portal will reject files over 1MB silently in some cases — the upload appears to complete but the document is not actually attached. After each upload, check that the document appears in the "uploaded documents" list before proceeding to the next one.

Common Upload Errors and What They Mean

"File type not supported": The portal accepts PDF and JPEG/JPG. PNG, TIFF, DOCX, and other formats are not accepted. Convert all documents to PDF before uploading.

"File size exceeds limit": Your file is over 1MB. Compress and re-upload.

"Document upload failed": This generic error can mean the portal timed out or the file is corrupted. Try downloading the document again from its source and re-uploading.

"Application not found" when trying to add documents: This occasionally occurs after the session has been idle for more than 15 minutes. The portal has a timeout that is not visible on screen. If you experience this, do not re-submit — log out and log back in. Your in-progress application is saved to your account.

Completing the Payment

The IRP registration fee is €300, payable by credit or debit card at the time of submission. The portal does not accept bank transfers, PayPal, or cash.

The payment page appears as the final step before submission confirmation. Once you pay, you receive an acknowledgment email — keep this email. It contains your OREG reference number, which is your tracking reference for the application.

After Submission: What to Expect

You will receive an acknowledgment email within a few hours confirming your submission and providing your OREG number.

Your application status in the portal will typically show as "Inactive" for the first 8 to 12 weeks. This is not a problem — it reflects that the application is in the queue but has not yet been assigned to a caseworker. It does not mean your application has been rejected, paused, or flagged.

When a caseworker begins reviewing your application, the status will change to "Active" or "In Progress." Decisions are typically communicated by email, often on the same day the caseworker completes their review. If your application is approved, you will receive a notification to register your IRP card (where you pay the fee if it was not collected at submission) or confirm your card details.

If ISD has a query — a missing document, a discrepancy in your records — they will contact you by email. Respond promptly and completely. A query response that doesn't fully address the question will result in another follow-up round, adding more weeks to the overall timeline.

If You Need to Travel Before Your Card Arrives

Your current IRP card may expire during the 10 to 16-week processing period. As long as you submitted your renewal or upgrade before your current card expired, you remain lawfully resident in Ireland and can continue working.

However, international travel during this period is strongly discouraged. If you leave Ireland with an expired IRP card, even with a valid submission acknowledgment, you may encounter significant difficulty re-entering. The acknowledgment email demonstrates you have an application pending, but it does not guarantee re-entry.

If you must travel internationally during the processing period, contact ISD in advance to discuss your options.

The Full Application Picture

The portal walkthrough is one part of the overall Stamp 4 process. The preparation that happens before you log in — calculating your eligibility date accurately, gathering the right documents, addressing any Revenue discrepancies, preparing the employer letter correctly — is what determines whether your application goes through cleanly or generates caseworker queries.

For a complete guide covering eligibility calculation, document preparation (including what to do if your employer won't cooperate), the portal submission process, and the citizenship timeline that follows Stamp 4, the Ireland Stamp 4 (Long-Term Residency) Guide covers the end-to-end journey.
