我老来小结一下剩余名额分配的问题

1. 7％和28.6％只有在不使用剩余名额时才有意义，对于剩余名额分配不适用7％和28.6％原则，某些不断重复7％的ID可以歇一会了。说明看这里：http://bbs.legalimmigrant.org/viewtopic.php?f=6&t=906

2. 剩余名额先给EB1，这个大家都没反对意见。说明看这里：http://www.mitbbs.com/article_t/Immigration/31262131.html

3. 剩余名额给过EB1后是应该先给EB2再给EB3 还是 同时给EB2 EB3？也就是该Horizontal spillover 还是混合spillover的问题上大家在抠字眼（纯垂直spillover对于中国EB2，EB3都没好处，一个剩余名额都拿不到，大家就不要傻乎乎地支持了）。对于这一点，冰机灵icecream08 同学说：
ACT203 says:EB3 can get "any visas not required for EB1 and EB2"
It doesn't say: EB3 can get "any visas not required for EB1 plus any visas
not reqired for EB2".

When talking about legal wording, do those two have the same meaning?

When I read ACT203, my understanding is EB1->EB2->EB3, unless ACT203 changes the wording specify: "any visas not required for EB1 plus any visas not reqired for EB2".
