看移民法，它的规定是党员党籍终结必须在递交申请的两年或者五年。我的理解是美国的申请人递交I30表前的两年或者五年必须终结党籍， 而不是受益人前往领馆面试前的两年或者五年终结党籍。
如果是兄弟姐妹移民，一般要等13-14年，也就是说，受益人必须在15-16年前就得退党。
我的理解对吗？
An immigrant may be excepted from inadmissibility under INA 212(a)(3)(D) if the immigrant can establish that:
His or her membership in or affiliation with a proscribed organization terminated at least 2[63] or 5 years before the date of receipt of the application (if the immigrant's membership or affiliation was with the party controlling the government of a foreign state that is a totalitarian dictatorship as of such date, the immigrant must establish that his or her membership or affiliation terminated at least 5 years before the date of receipt); and
