<p>I was wondering, if a teacher is submitting my rec letter by mail, do they need to write my columbia ID on the envelope?</p>
<p>Do they just address it to the admission and the letter will be sorted into my file? </p>
<p>And also, if I'm sending supplementary material, what if I haven't yet received my Columbia ID yet?? I'm not an US citizen so I cant write my SSN either.... (14 days is exceeding the deadline since I submitted part 1 yesterday) *Gulp.</p>
<p>So screwd.....please kind souls, any ideas?</p>
