What does "cancel without judgment" mean on American business visa?

American visa "unbiased" is a fixed legal term. This is "unbiased cancellation", for example, if the US embassy or consulate issues the wrong visa date or other errors, or applies for a new visa of the same type, covering the validity period of the previous visa. This chapter only shows that the visa expired normally before, if it expired, it was not caused by other violations. This will not have a negative impact on future new visas and entry into the United States.

The official English interpretation of this phrase is as follows:

Unbiased cancellation: the seal affixed to the visa by the American embassy or consulate when there is an error or the visa is a duplicate visa. Does not affect the validity of other visas in the passport. This does not mean that passport holders will not get another visa.

Different countries have different regulations. For example, the Australian visa is stamped "No further travel".
