I have applied (on February 17th 2020, GMT +1) for a PhD position (in Australia) starting the latest in July (so, no application deadline). It has now (March 7th 2020) been nearly three weeks ago since I emailed my application. I did not receive any confirmation email of receipt from the professor. It is something I really loathe, because I do not know what the status of my application is. Contrary, I can image that reading applications and making inquiries with the funding organisation in respect to the applications can take up a lot of time. Thus, I do not want to appear impatient. I wonder, however, if further patience is prudent. In short, should I email the professor about the status of my application or should I wait a few more weeks?
