Thanks for the advice, Superrob!
If we have recently returned the "yes, keep me on the list" card, should we also send a LOCI? Or, is that an annoying overkill?
I don't think it's annoying at all. Just be sure to write specifically why you're interested in the school. If you're planning to visit soon, it might be better to combine the LOCI with the "thank you" note you mentioned earlier.
FYI, my actions so far have been:
- Send "please keep me on the list" form with LOCI (listing specific interests about the school - limited b/c already stated on PS)
- Send 2 additional LORs (confirmed that school would accept them)
- Visit (1 LOR was in by then, 1 later)
I am also planning to send an additional LOCI soon, together with an updated resume. I am just waiting for my grad school grade to come out next month to update it.
I don't think schools have a problem with periodic updates - so long as you don't call them every day. I hope everything works out for you!
