1. First of all, we need to find out the real reason for refusing the visa. We can go to the consulate to make an inquiry, but the complaint needs to be made in person, but the consulate will give a reply within 1 month after receiving the formal complaint. The only advantage of inaccurate time is that you don't have to hand in the previous materials, just need to hand in favorable supplementary materials and evidence. However, the appeal is only valid 1 month before the visa is refused.
2. As long as you can submit enough supplementary documents or certificates, you can reapply. However, anyone who is refused a visa will generally apply for an interview time without an appointment number. It can be expedited through some agencies or intermediaries. So as not to delay the travel time. It is best to delay the first refusal. Although there is no time limit, if you apply immediately, the probability of rejection is relatively high.
It is not the most important thing how long it takes to apply for a German visa if it is rejected. Some applicants will ask a few questions when they meet the visa officer, and even refuse to read the materials directly. For this problem, visa officers have to deal with thousands of visa applications every day, and all of them have a certain refusal rate. Therefore, the visa officer began to review you from the moment he saw your 1 eyes. Most of the information can be obtained quickly on the visa application form. At the same time, your appearance and manners can also reflect your cultural influence. Visa officers who have signed thousands of applicants face to face also have their own "refusal faces": such as rough and dark skin, erratic eyes, sitting left and right, wearing a blue suit and red tie, and so on. These will be the reasons for refusing the visa. The rest is to re-prepare the materials, or you can contact the frequency network for consultation and solve the problem according to the reasons.
