It's a good idea to apply for your Ireland Visit Visa 8–12 weeks before you want to travel. How long it takes to process your application can change based on where you're applying from, what time of year it is, and how many applications Irish immigration is dealing with. Expect longer processing times during busy travel times like summer or big holidays. Applying early means you're less likely to have delays and will have enough time to get ready for your trip once your visa is approved, like booking your flights and hotel.
