無限感激8老師指點！
另，如果有風險(但我是在入境後才收到NVC案件繳費遞知的，是否風險小點啊?）。-Irrelevant.
如走加國簽證中心，還是要P1-4一步一步來，要耗費一年時間吧?
-depends on whether the PD is still current. If it will be current continually after August, it may take several months (less than one year for sure). But if the 排期 retrogresses, then NVC will stop processing your case there until the PD is current again.
