<p>Basically my teacher sent the recs on 12/05/07. However, I haven't heard if the colleges that I'm applying to have received them yet. How long does it take to receive confirmation? Thanks</p>
<p>Colleges will usually let you know if you're missing anything around February or so; whether they get back to you earlier will vary depending on the college. Some schools allow you to track your application online; I don't know if that's an option offered by the colleges you applied to.</p>
<p>Some schools take up to 6 weeks to process things like that, especially in December. Don't worry about it.</p>
