<p>I've done research for 3 profs at different institutions, and only 1 of the 3 is from my university. Is it ok for me to submit letters from these profs, or do grad schools prefer letters from your home institution? Does it look bad if only one of the letters is from a prof at my university (especially if it is more well-known than the other two institutions)? Or, is research the real focus, and it would be ok since I did research with all 3 of them?
Thanks for the responses!</p>
<p>Research is the focus. The home institution of the professors will not be a factor.</p>
<p>I didn’t have any recommendations from my undergraduate institution PIs. I don’t think it matters.</p>
