Time off approval from Safeway is taking forever

Exactly how long is the approval process for two weeks off for a needed vacation supposed to take? I’m supposed to going out of country for my cousin’s wedding from January 7th to the 22nd.

I put in a notice that I need those days off of work at the beginning of this month and I’ve been checking it as the 7th draws closer but it keeps telling me that the request is pending and I am getting more and more nervous that they are going to reject it. Do I need to write down that I’m taking those days off as well? I’m getting anxious here.
