Is it normally appropriate to ask my writer (DO) to resbumit a LOR that appears to be lost? If so, how would you ask politely? I don't wanna sound like another neurotic premed but it is holding up my secondary essays and I have an interview coming up on September 12th, which requires a LOR from DO to be sent by the date. It has been about 10-14 days since the letter was mailed out and it should been received at Interfolio by now (based on my previous experience, it only takes 5 business to show "letter received"). Thanks in advance.
