I am a PhD student studying here in Northern Ireland, UK on a Tier 4 visa. I am an Indian national. I have to visit Italy to attend a conference. Can I apply for a Schengen visa through the Italian Consulate in Belfast?
The Italian Consulate in Belfast is an Honorary Consulate, with limited hours and limited services.
According to the site of the Italian Consulate in Edinburgh (which covers Northern Ireland), due to the need to collect biometric data (fingerprints), you can no longer apply for a visa through the Honorary Consulate in Belfast. You have to apply at the Consulate in Edinburgh.
The site describes the procedure (including link to the booking system), required documentation, etc.
