Incorrect B1 Annotation, but is within VISA Validity

[windsurferlad]

Question please.... I got approved for a VISA one time entry. The letter from my company has the dates as 29Oct - 7 Nov ( these were apparently tentative ) its been rescheduled to first week of December. Visa Validity is until 22 Dec.

Will this be a problem or can I still enter so long as within validity? I am worried of the annotation of 29 Oct - 7 Nov on the visa.

I will still travel within validity date. Just not on the dates annotated on VISA.

Please assist.
