I was told to ask and then inform them when you need it.
Is there any other way to do that?
So if I ask them in third year just have them hold onto it until eras next year?you will fill out a request form on eras once the application cycle opens. the eras form will have your attendings name and a unique identification number. you email them the pdf file. when they have written the letter they will have to upload it. it takes about 5 business days from when they upload the letter to when you will be able to see it.
