I applied for ED and submitted my app a couple days ago. Almost everything has been verified and received (transcripts, test scores, observation hours) except one LOR. I had a feeling my employer would not have time to do the LOR before the deadline, but I have 3 other LORs. In order for my application to be fully processed, will PTCAS wait for my last LOR or will they just process it without the last LOR? I still want to give my employer time to write an LOR in case I have to apply for other schools after finding out the ED decision so I don't want to delete her off of my application, but if it is keeping my app from being processed I'll delete it.
