H1B Appointments (India) in coming months

Hi Community,

Has anyone been successful in scheduling H1B appointments in any US Consulates in India for the months from Jun - Aug ? Please let me know. The earliest I see available is in Oct end - Nov beginning, nothing before or after that ? Is it because all slots are booked from now to October or the system is not released to book slots for these months ?

Any help is greatly appreciated.

Thanks,
Arun
