From my point of view . All Tibetan who hold titre de voyage they give only 30 days visa . For Payment u can pay by cash or by credit card it’s upto you . You can summit ur wife and child visa at Vfs . But let them know that they’re your family , otherwise what I heard is that they charge for courrier service 30€ if the persons is not available while summiting visa . So if u say them they’re ur wife n child so that u pay only visa fee not courrier .

@ thank you so much for the reply. I heard some Tibetan stay one month and then extended few days more to stay. If any idea , please make a video on that.. for deposit go to vfs n for withdrawal go to vfs too or go to ambassador ? Sorry for more questions. Thank you again
