According to the U.S. Embassy in India website:
All visa and VAC appointments, both in-person and interview waiver, at U.S. Embassy New Delhi and the consulates in Chennai, Hyderabad, and Kolkata are cancelled until May 15 and at the consulate in Mumbai until May 28.
The site further indicates that officials are “currently unable to reschedule any cancelled appointments” or “speculate on or respond to inquiries regarding potential future cancellations or appointment availability.”
Given the current state of the COVID-19 crisis in India, new students may have difficulty scheduling visa appointments. We remain hopeful that the challenges in India will improve soon and that students will be able to join the University community in August.
