> Am I able to do the 60 days extension on the same day as the cancellation?
Yes you can. You will ask for a 60 day extension of stay based on unable to travel due to COVID-19.
>Will it be processed on the same day?
At MOST immigration offices, you will be given an "under consideration" stamp. This "under consideration" stamp is like a temporary extension of stay. You will need to return to the immigration office that issued the under consideration stamp to close it out.
>I was told it takes 15 days to process the covid visa
For immigration offices that issue the under consideration stamps, it can take between 7 to 30 days, depending on the immigration office and their workload.
