第一次寄来的打指纹信和这次寄来的信service center 都是NCS,第二次寄来的说第一次指纹没过要求重做的信service center是WSC.
请问1.WSC是哪个中心?
-WSC means "Western Service Center" - another name for CSC.
2.为什么会是不同的service center?
-Probably your case was located in CSC (WSC) at that time. It is normal for USCIS to transfer your case between their service centers during the processing period of time.
