Due to a strike, the Greek Asylum Service will have today on 31st of May, only very limited translation services. That means if you go, there might be no translator to translate for you. If you have a scheduled appointment today, you should definitely still go, but there is a chance that your appointment might be rescheduled. If you don't necessarily have to go, you might consider to go the Asylum Service when the strike is over. On their Facebook page, the Asylum Service apologized for the inconvenience.
