Hope you have intimated them well in advance with a proper reason for delay so they consider to give an exception and grant a time extension.Hi. AOR march 8th 2019.,I got my medical request on 25th match 2019 and I suppose to do it before 25th of April but I'm going to do it on 2nd if may. I mailed them informing this. Will this affect my visa process ?
They mention that "You are required to undergo the medical examination within 30 days of the date of this letter. Failure to do so may result
in the refusal of your immigration application."
Nobody can assure you about this except for IRCC. Now that its past 25 Apr, call them and find out.
