Hi Guys. I've been working for some time on my application. My only problem, and probably a big one, has been contacting POI's. I haven't heard back from anyone I contacted. Should this be a deal-breaker? Instead of contacting POI's I feel like I should be focusing more on the statements of purpose and personal history. Being an international student I don't know if not getting in touch with a POI translates into already out of the race.
