My verification took place in different ways on different sites. Sometimes it took several hours, and sometimes you had to wait for several days. Over time, I realized that a lot depends on the accuracy of the data provided. On winthrone registration , for example, the process turned out to be quite fast, as the requirements were clearly stated. I immediately uploaded the necessary documents, and the verification was carried out without additional requests. This has shown that with the right approach, delays can be avoided.
