I am filling out theDS-260 Online information page - in place of the old DS-230 form and the website keeps asking me for an Invoice ID number. I have looked over all of my information, especially the e-mails and letters from NVC (which informed me that I can now schedule for an interview) and I cannot locate the Invoice ID number anywhere. So, my questions are many-fold: 1) Where can this number be found and how do I request for one if it was not included in the information I have already been provided? 1.5) Is the Invoice ID number only given to me once I have paid for the interview? 2) Also, the payment for the interview and application, must it be paid before going in to the consulate for an interview or can it be paid in the consulate itself prior to interviewing? 3) Last question - do I need to complete the DS-260 form prior to scheduling for an interview or can I schedule an interview first without completing the DS-260 form, as I have only used and submitted the DS-230 form before?
