Sending recommendations

<p>I have two questions about sending my recommendations. I am an international applicant, and I hope you can answer them.
1) I invited my teachers using the Common App online system, and they agreed to send their recommendations electronically. I know some colleges require their recommendations to be typed on official letterhead, so I was wondering if that requirement holds for recommendations submitted online.
2) I also have to send some additional recommendations by mail, so I have to provide envelopes. But what do I have to write as a return address - my address or my recommender's address, or it does not matter?</p>

<p>Your goal is to avoid any concern about authenticity of your recs. Online submissions don’t have to be on official letterhead, but it helps. For the same reason, use your recommender’s address as the return.</p>

<p>You can ask your counselor to write the school’s address as the return address. I called the admission office of psu and that what they told me</p>
