小白求教一个填表的问题

小白觉得问题可能很可笑，但我真的查了一下很纠结

Are you legally eligible to work in the US? yes/no

查了一下最简单版解释是，if you are allowed to work in US.
复杂点，if you are a citizen or green card or .... or none citizen but allowed to work in US.
于是神马是allowed to work in US啊……

感觉US在读master都是allowed的吧……不是的其实可以抽opt也叫allowed？可按我这么理解就没有不allowed的了吧？
所以神马是allowed呢？所以这个是yes还是no呢 =.=

然后这个也是yes吧
Do you currently need or will you someday require, - to sponsor work authorization for you to be hired in the US?

感觉自己好像真的是小白，请各位误鄙视 >.<
