回复 Xiaobaitu, I was confused about this kind of question?

My case was transfered from VSC to TSC. I thought my AP application also need to file to TSC, the same thought as a friend here. However, before I file it, I call USCIS to ask about where I file to. The USCIS representative told me that i need file the AP application to the original service center- VSC. even though I already filed to VSC, I am wondering whether or not I did right, since the USCIS'representative often made mistake. so could you please help me to make sure that ?
Thanks.
