I have applied for a CR-1 visa as the spouse of a US citizen. My visa interview appointment has been scheduled at the Mumbai consulate. The Mumbai pre-interview instructions (https://travel.state.gov/content/travel/en/us-visas/Supplements/Supplements_by_Post/BMB-Mumbai.html) say that a Visa Application Center biometrics appointment is required prior to the interview. According to these instructions, I need to schedule this appointment at https://www.ustraveldocs.com/.
I created an account on that website as an immigrant visa applicant, and now it is prompting me to start a visa application. I am confused by this, as I have already applied for the visa and am just trying to schedule an appointment. Am I supposed to fill out this application form? Or is there something different I need to do in order to schedule the appointment for biometrics?
