In fact, the visa application has been passed, but the materials are insufficient, otherwise the passport will not be taken away and sent to the post office for collection.

The problem is that the visa performance was abnormal at that time, and the materials in hand were unclear, which made the other party doubt whether the working ability met the conditions for issuing a business visa.

Therefore, they want you to supplement your resume to further verify your visa qualification. There are many such situations. If several people in a company apply for visas, it is inevitable that some idle people will travel with business visas.

The application must be reassessed. You can send a fax to confirm that they have received the resume, and you can try to ask when you will get the result. Of course, the answer is usually please wait patiently.
