Effective immediately, the Atypical Working Scheme (AWS) in Ireland will now require applicants to use approval letters from the Irish immigration authorities within 90 days of issuance to avoid having a fresh application being submitted.  The AWS is allows non-EU nationals to enter and work in Ireland for between 15 to 90 days. The potential impact of this is that visa nationals requiring a letter of approval for entry clearance to Ireland, who do not travel scheduled within 90 days will have to re-start the application process.
