If you come from a country which requires you to obtain a visa to enter the Schengen area of the European Union (see link: https://maee.gouvernement.lu/fr/services-aux-citoyens/visa-immigration.html), we can help you get your visa. We can send an official letter of invitation and cover any visa fees.
The only thing you need to do yourself is to apply for a passport allowing you to travel overseas – if you don’t already have one. If you already have a passport, you must ensure that it is valid for 6 months on the date you intend to travel to Luxembourg. If this is not case, you’ll need to rapidly complete any formalities for renewing your passport.
