As you said I will wait and yeah being proactive would not be any help but I would say it's better to confirm with them....not sure what to do apart from waiting...Does anyone else having this kind of situation ?From what I understand - and feel free to correct me if I am wrong - its not necessary that they will ask you to redo your medicals if they do expire. In several instances if your medical has expired while they are still processing your application, they could extend the medicals for you. However, if they do need you to redo your medicals - they will directly reach out to you. I don't think being pro-active on this point would be of any help. Provided you reach March 14th without any update on your application, you just have to wait for them to tell you whether they need to redo your medicals or not.
