If you need a visa to enter Belgium, you might want to do that in advance, as it takes about several weeks / months to process your application. Please check the website of the Federal Foreign Office to find out if you require a visa to enter Belgium.
As a rule, visa applicants must appear in person at the embassy or consulate responsible for their place of residence to submit their application, supported by all necessary documents. Visa application forms can be obtained from the embassy or consulate free of charge (in the local language).
As we are only able to generate invitation letters for visa application through the registration site, it is important that you complete the online registration process to obtain your letter.
