F2 visa: Minor possible mistake in DS 160 form after visa interview appointment

[vivxyz]

Hi,
My wife is applying for F2 visa from Kolkata on Aug 12 while I am on F1 visa in US. In DS-160 form she selected YES for the question "Are you the Principal Applicant" under "Travel Information" section, though she will be seeking F2 visa. I already took the DS 160 confirmation with bar code and scheduled her visa interview.

So, is this information right on DS 160 form (i.e. can a F2 applicant be considered as principal applicant) and if not can she still go ahead with her visa interview or does she need to update this information in DS-160 form and scheduled a new appointment. Please reply urgently. Thanks,

Vivek

This may not be a problem. But you can check with VFS.
