Absolutely. Your application can be entirely submitted in French, English, and German. All fields will appear in these languages. To do so, just go into your parameters (once logged in, click on the little wheel in the top right) then change the language. Once your application is submitted, the agency will see your entire application like any other in her working language. Everything is translated except for the manuel fields you entered (such as ‘Motivation’ and ‘A few words about us’ which you will have typed). No problem therefore to submit your application in another language.
