France as Main Destination: the Schengen rule of competency
Only GNIB card holders (valid Irish residency permit) are entitled to apply for a Schengen visa at the embassy of France in Ireland.
Visa applications must be submitted in the embassy corresponding to the main destination country.
Is considered as main destination, the country where you will spend the longest period throughout your first trip. Number of days and nights are taken into consideration.
For example: During one trip you plan to visit Belgium (3days), France (6days) and Italy (4days). France is considered as your main destination and you must apply for a visa at the French embassy.
In case it is not possible to determine only one main destination, you will have to apply for a visa at the embassy corresponding to the country you will first enter among your main destinations.
For example : During one trip you plan to travel to Germany (3days/2nights), Spain (5days/4nights), France (5days/4nights). As you plan to spend the same number of days and nights in both Spain and France, you must apply at the Spanish embassy (first entry among the 2 main destinations).
In case you plan more than a single trip, you must apply for your visa at the embassy corresponding to the main destination of your first trip. You are entitled to apply for a visa covering all your trips if you provide details of your next trips (flights bookings, hotel bookings, travel plan...).
