I am a medical student, planning to do a 2-month-long clinical rotation in the USA. I applied for a B1 visa, provided a letter of invitation, stating that my clinical clerkships will last from May 6, 2024 till June 28th, 2024. I just got a one-time visa, with an issue date of 22nd of September 2023, and an expiration date of 30th of June 2024. And annotation saying that I need to attend clerkships from May 6, 2024 till June 28th, 2024.
Unfortunately, my plans changed, I need to arrive in the US in April, 2024 to start my rotations.
Will that annotation date restrict me from entering the US? What should I do in such case, when I need to enter before the annotation date?
