I have worked in Y for 2 years as a research assistant and then I moved to my home country and worked here for almost 4 years and published papers in reputed journals. Logically I think I should include the names of my current supervisors or the supervisors I have published works with.
But Professor X (I am applying for a Ph.D. position) is originally from Y, currently residing in Canada. He asked me to include three references from Y. So I wrote the supervisors I have worked under. So basically I wrote three of my supervisors two days ago and asked for their permission if I can include their name in my application and none of them replied yet. Maybe things are difficult due to this pandemic. In this situation what should I do? Should I write Professor X that I could not reach them? Or just send Professor X the list of names? what if Professor X contacts them and they don't reply? (I am restless because Professor X is waiting for my reply too)
