International students hoping to study in Ireland at University College Dublin International Study Centre must apply for a Study Visa (Long Stay).
Firstly, you need to apply to a course at the International Study Centre and receive a Letter of Acceptance. You can then apply for a visa online via the Irish Nationalisation and Immigration Service's (INIS) website, AVATS. Make sure you read the visa application details carefully, and provide all the required documents. The process is as follows:
You should apply for your visa as early as possible to make sure there is enough time for it to be processed. This normally takes eight weeks, but can take longer in busy periods.
If your visa application is rejected (as long as you did not provide incorrect information in your application), you can challenge the decision within 2 months of receiving the letter of refusal. Write a letter explaining in detail why you believe the wrong decision has been made. You should refer to the reasons why the application was refused, and add any new information you believe is relevant.
