H1b Visa Extension Stamping Dates

[Raj_cv]

Hi All,

I'm in US. Got H1b and H4 extensions. Looking for stamping dates for the month of Nov or December.
Not able to find any in Hyderabad or even in Canada or Mexico (big locations like Mexico City, Matamorus etc)

Any idea why? Do you think new dates may open up?
Please share your thoughts. Also what other options do I have to get it stamped?

Thanks
Raj
