<p>I had my dean fill it out, and he handed it to me to mail it. Is this normal? I asked him, and he said he was to busy to mail it. He just filled everything out and handed it to me. Is there supposed to be some special envelope with a school seal the college sends?</p>
<p>As long as it is on letterhead and signed by him with his contact information, you should be ok. You can always ask for an envelope from someone in the department which should have their information printed on it for the return address.</p>
