From 1 October 2026, third-country nationals who wish to reside in Luxembourg and fall under the jurisdiction of a Belgian embassy or consulate representing Luxembourg must follow the procedure applicable at the competent Belgian post or, where applicable, its external service provider (ESP).

Applications for a long-stay visa D must be completed through Visa On Web, in line with the instructions of the competent Belgian post.

The previous procedure based on a separate temporary residence authorisation (AST) no longer applies to new applications. Temporary residence authorisations already issued remain valid under the conditions stated in the relevant decision.

A visa D is required for third-country nationals who intend to stay in Luxembourg for more than 90 days.

Your main purpose of stay determines the category you must select and the documents you need to provide.

Where and how to apply

Applications must be completed through Visa On Web and submitted to the Belgian embassy or consulate responsible for your place of residence.

Where the diplomatic post works with an external service provider (ESP), applications must be submitted through that provider according to the arrangements stated on the diplomatic post’s website.

Before submitting your application, make sure you:

• select the category matching your main purpose of stay;
• check and print or download the relevant checklist;
• complete the Visa On Web D visa application form accurately, then date and sign it;
• make an appointment according to the instructions of the competent Belgian post or ESP;
• attend in person with your Visa On Web form and all required documents;
• provide the required originals and legible copies, together with any required translations, legalisations or apostilles.

The documents required depend on the category selected. The relevant checklist explains the requirements for originals, copies, translations, legalisations and apostilles.

The Belgian post or ESP will carry out the required checks when you submit your application. You may be asked to provide missing documents or additional information. The Luxembourg authorities may also request additional documents during the processing of your application.

The file is then transmitted to the competent Luxembourg authorities.

The decision on the long-stay visa is taken by Luxembourg’s Ministry of Home Affairs, Directorate General for Immigration, except for certain categories, such as Working Holiday Visas, which fall under the responsibility of the Ministry of Foreign Affairs.
