How long will the Schengen visa refusal record be cleared?

I don't know. It is permanent. According to relevant information, the visa refusal record will not be automatically cleared within a few years, and it is permanent. You can apply unlimited times, your records will appear on the screen of immigration officers unlimited times, and it will have a chain effect, that is, exchange information between the exit and entry administration departments of western federal countries. If the United States refuses the visa, the Canadian or British immigration authorities will also have corresponding records and can also find them.
