When do I send out my college invitations to my LOR Teachers?

I already have 2 teachers who have agreed to write me an essay, but I was wondering when I should send them the invites to the colleges? I think It’d also serve as a good reminder for them to write the LORs.
Thanks!

Also, would it be better to talk to them in person or to shoot them an email, to inform them that I’ve assigned them to my colleges?

If they agreed to write you LoR some time ago, it would be good to thank them in person or by email which would also serve as a reminder. Then you may invite them anytime when you are working on your application. Do allow at least a couple weeks before the deadline for them to response though.

Alright, thanks for the advice!

When you talk to the teachers in person ask if there is anything you can provide (ex. a resume or list of activities/accomplishments) that would help them write the letter.
