As one of my friend got refusal for visit visa and they give him reason that "Your intention to leave the territory of the member states before expiry of the visa could not be ascertained. My question is if he wants to appeal , he has to take appointment again for german embassy to submit letter in person and in the letter that he received they mentioned information regarding appeals that " an action with the Administrative Court in Berlin" , what does that mean ?
Which is the best way to get a visa as soon as possible - by appeal or applying again?
