b1/b2 was rejected in 2013 year.
then, h1b visa from 2016 from Mumbai as 1st visa, no rejections on h1b stamp. no any visa rejections since received h1b.
h1b visa recent stamp from 2022 from Thailand Bangkok embassy.
Now recently, got approval for 2025 to 2028 for the h1b and h4, question about dropbox eligibility.
For the dropbox eligibility some sites tell:* You did not face any US visa refusals in any other visa class since H-1B issuance.
and some other sites tells: no any refusals ever.
Question 1: please advise. If I am eligible for dropbox.
Question 2: If H1B and H4 stamping appointments are only available at Chennai or Hyderabad?
Question 3: should I file the DS160 with Mumbai and then still same is usable for Chennai to book appointment if not eligible for dropbox?
