My dad's tourist visa to US is expiring with in a day. I applied for renewal. Basically it was new application ( DS 160 ) form where i needed to give passport/previous visa info. I do not rememeber anywhere explicilty selecting renewal. Then, I went on to another site, to again provide basic info + pay fees + schedule appointment. All this took many days as it won't take non-indian card. So finally i paid fees and it asked me to schedule appointment. So when i picked enabled dates, any, it said no interview at this time. So my concern is - We wanted to select 'Interview Waiver' Since it is renewal and in covid i do not want him to travel all the way to embassy which will be 1.5 day travel for him even for passport drop off. But i did not find any option for interview waiver. however instructions said, once you schedule appointment for interview, there will be questions to determine if i am eligible for it, then i schedule document drop off date. 1. I am not able to move forward at this point in application workflow at all. 3 months of dates it shows, but no date is working. 2. Suppose, If i am able to find dates for document drop off, will my dad have to drop off physcially? Can it be couriered? Whole point is to avoid travel. For them it is safe person is not coming inside but his travel will be same. 3. What kind of letter to request interview waiver, need to provide and where? 4. Any phone/email for helpdesk where they can atleast tell how to navigate in application I am completely stuck now... Fees are paid and non-refundable. Anyone recently renewed visas.
