I passed the interview for a postdoc position some weeks ago, and the department asked me for various documents so they could begin the mandatory background/references check. I sent in the files pretty quickly (~2 weeks ago), but did not receive any confirmation that they got my email, or any kind of follow up. My references also did not get a call. I assume the international background check part is what's taking so long, since I am very sure that my documents must have been in order (I was very careful in preparing them).
However, I need to decide between this offer and another one this week, and in order to make this decision, I need to see the details of the actual offer they will have for me. I already negotiated a starting date and some other things with the administration, but I'll need to see the proposed contract to be able to compare to the other one. How do I politely ask for an update without annoying anyone or sounding pushy?
