Use ninety days and course duration to organise the Ireland timeline
Irish Immigration Service guidance says study-visa direction varies with course duration, and a planned stay over ninety days also needs registration after arrival. Leave links between course finish, housing move-in, flight and possible registration appointment rather than treating visa approval as the end of every step.
Make AVATS fields match school payment and housing records
Use official AVATS guidance for name, passport, address, course and travel fields. Dates, amounts and contacts in offer, course fees, payment evidence, housing and funding explanation must correspond; submit a truthful update if asked for more evidence instead of carrying forward an old address or course.
For longer English study, ask what school support and post-registration duties mean
For a course beyond a short arrangement, ask the school about reporting, attendance, insurance, housing, holidays and support after arrival. Registration, residence or renewal is not a result a school can decide for the student; confirm current conditions separately with Immigration Service and school before transfer, extension, work or departure and re-entry.
