VISA Thumb and Interview Process:
Thumb Day:
On the DS-160 form, there is a "Completed On" date. This date must be within one year before the interview date.
For example, if you are attending the interview on January 2, 2024, the "Completed On" date should not be earlier than January 2, 2023. If it's incorrect, log in to the portal, update the date, and print the corrected form. Carry this updated printout with you. Otherwise, they might send you back, asking you to correct the date and return.
Today's required documents: Passport, DS-160 form, and appointment confirmation letter. These two printouts along with the original passport. You must attend with your thumb ready.
Interview Day:
Whatever information you entered in the DS-160 form will be asked during the interview. You must answer accurately and exactly as you filled in the form.
For example, if it’s about your date of birth, ensure you provide the exact details as mentioned in the form. Don’t provide more or less information than what’s in the form.
Today's required documents: Passport, DS-160 form, and appointment confirmation letter. These two printouts along with the original passport. If attending for B1, invitation letters are also needed. Additionally, original certificates, Xerox copies, salary-related payslips, and any other necessary documents would be better to carry.
I attended for B1. If someone else is inviting, they ask for a copy of their visa or passport. I heard them mentioning this there.
If you are going for this process, follow these steps. All the best!
