I assume you meant 10/25 instead of Sept as you are claiming it's only been a week. I fail to understand the nature of your worry. Your company paid premium processing so it should be processed within 2 weeks. If it's only been one week, what is it that you are worried about? Your statement about the 2 days of acceptance status is simply incorrect, no idea where you got that from. The online system cannot be relied upon and it's merely informational and often innacurate. USCIS will issue something before the 15th day because they want to earn the premium processing fees.
