Acquiring LOR second time applying

[Cooper2000]

Hello, 

I am currently planning on applying to PA school this upcoming 2024 cycle and am concerned about my chances on getting in the first time. I wasn't planning on applying until the year after however I have the hours and prerequisites and thought I should give it a chance now and see where I stand. That said, I was curious how the letters of recommendation work in the CASPA application. I have a few lined up that were planning on writing me letters but I know they have to be submitted directly into the CASPA portal. If I am rejected this year and have to restart the CASPA application the following year will I have to reach out to everyone again for new letters? I am also concerned that if I were to wait too long or re-ask for letters they will not remember me as well.

Yup, have to request them again unfortunately.
