<p>Officially, you’re not supposed to count foreign language as English/Social Science (unless Libby Pearson was lying to me). Even if you do it won’t be an auto-reject. The adcoms start reading your application the moment one rec is processed into your file, so practically speaking you don’t even <em>need</em> two recs. So, they seem very lenient regarding certain rules, and I’m sure using foreign language as one of your main recs falls under that lenient category.</p>
<p>Regardless, just follow the rules. It’s not a big deal.</p>
