H1B Renewal dropbox appointment dates

I’m trying to get H1B renewal dropbox appointment in India for Dec’23 but the dates are not available to select. Looking for advice how much in advance we can take dropbox appointments in India.
I have already paid the stamping fee (last month) and no dates are coming to select.


You can book any available appointment before the visa fee expires and then reschedule if early appointment is available.

Thanks Kalpesh! Do you know what duration visa fee is valid ? I have already paid fee last month.

One year.


Thanks again… this is very helpful information.
