So I applied for a number of REU sites earlier this year. So far I've only heard back from one (and they didn't accept me). As the end of the academic year approaches, I need to start considering where I'll live and how I'll employ myself during the summer, but I've been putting off those decisions until I received some notification from the REU sites. Would it be bad etiquette to contact the respective directors? Have any other undergrads here not yet received any information regarding REU sites they've applied to? I'm thinking the silence doesn't bode well for my chances.
