I just registered my interview appointment on the website. The consulate website says: "Each visa applicant on your case must separately register his/her appointment online before the interview." When I was registering my appointment, I was asked if I want to add another applicant and I added my wife and son as well. Now that I login, I can see all three of us listed there. Is this how it should be done or do I need to register my wife and son separately as well?
