Hello, my parents who are Indian citizens had applied for Canada Tourist visa during their stay in USA in May 2021. Since, their 6 months stay at USA was completed they decided to fly back to India. There has been no progress since then except for biometric on their application. In case they get passport submission letter, can they do so in New Delhi consulate or do they have to submit in US? Sending passport through FedEx doesn't seem to be safe option. Appreciate, any help. Thank you.
