Congratulations on your admission letter and I'm in the same situation as you (but still waiting for results..) I studied Biology in Bachelors and Health Communication in Masters (both outside the US though), and this year I also applied for PH & Comm programs.
I was wondering if I could send a love letter to some of the schools since I didn't receive anything yet. In the C.V. I mentioned a conference paper under review by ICA 2019 committee, and now its accepted. Shall I inform them of this?
