What comes first...status update or letter?

<p>My status just changed to say that they have all my materials and I will get a decision in the next 4-6 weeks. What am I going to get first? The status update or the letter? And does anyone know what the acceptance letters look like? Are the acceptance letters thick, and are the rejections thin envelopes? I think these next 4-6 weeks are going to drive me insane!</p>

<p>My D got an email saying to check her status. She did and it was updated with a "Congratulations!..." The acceptance letter, one page, thin envelope, arrived two days later.</p>
