Sometimes they will extend the medical, but not always they will let you know . In our case we applied in sept 2018 and the interview was in early December 2019, we were approved however they would not extend the medicals , my husbands medicals expire Jan 19 2020 and he is landing before this date . I do hope that they extend your medicals as it’s quite a financial burden to have to re do them. I hope all of you waiting receive amazing news in the upcoming weeks.
This process is frustrating and draining emotionally , so please hang in there and stay strong
