Ideally, we'd prefer that all your financial documents be in English. If that isn't possible, please just submit them in the language that they're currently in and we'll find someone to translate them for us.
We'd rather have documents from you in languages we need to translate than silly cat pictures or photos of your foot. You can email silly cat pictures to firstname.lastname@example.org.
Note: As long as you clearly represent your financial situation, the submission of silly cat pictures will in no way impact the outcome of your application.
