Did he apply onshore or offshore?
what kind of request you received from CO?..as now your status should be further assessment…
I recently spoke with an agent who suggested they may have cases where any applicant is located offshore on hold as once visa is granted they are giving some time to enter the country and currently the border is closed and there is no exact date when it will be open.
To put you in context the situation seems to be tougher now as there is cap for arrivals that even affects citizens and they are also requested to apply for some sort of permit to leave the country.
