Can I choose in-person interview if I am eligible for drop-box?


I came to USA holding my F1 Visa. Recently my H1B is approved and I need to get my stamping done. Since I already have visa earlier, when I am answering the questions as directed above, it is saying that I am eligible for drop box. Is there any other alternative to select personal interview instead of drop-box as I see some schedule available for personal interview and I want to utilize the opportunity.

Thanks in Advance.
