Picking up an L visa 2 weeks after submition

I live far away from an embassy and it is very inconvenient to stay in Chicago for many days waiting on my L type. Can I submit my passport, money, and forms, have it confirmed as valid 4 days later, and then pick it up 14 days after I submitted it? This way I would know everything is correct and I can just pick up it on the way to the airport. Thank you for any answers!
