<p>Hey all. So one teacher and my boss at my internship told me to write up a letter of rec and that they'll sign it (they did). My question is, can I mail them to colleges in the same envelope or will it cause suspicion that I forged them? The boss's letter is with a letter head and is signed/stamped with the company seal. Should take precautions (and double the amount of envelopes) and mail them separately anyway?</p>
