I have a B1/B2 10 years long valid visa that is expiring this week. I want to renew it. I had an F1 visa for a few years in between these 10yrs that is now expired. What do I write in the DS-160 form for renewal of B1/B2 in the column for the 'most recent visa'? If I put the expired F1 visa details, it then asks "do you want to renew the same category visa?" and I have to say NO. There is no place to give details of the old B1/B2 visa that I actually want to renew.
And also my B1/B2 visa is on a, now, expired, old passport!
Please help!
