 Is writing a letter of complaint a good idea if your visa application gets rejected?

If your visa application is refused, you should get an explanation letter from the embassy. This is referred to as a remonstrance letter, and you should react with a protest letter that addresses all of the grounds laid forth in the remonstrance as well as the reasons why you should be granted the Visa. Make it succinct and to-the-point! If your visa application is refused despite the fact that you believe all of your documentation is valid, you must file a written appeal with the German embassy. Because appropriate formatting is critical, you should get guidance before beginning to compose the letter.
