绿卡到手5年了。期间前2年半居住美国，后2年半大部分时间在中国。这种情况怎么做可能性比较大转公民？
-If you stay in China for > 6 months continuously, your physical presence continuity probably will be disrupted, and if > one year (with RP), the physical presence continuity will be disrupted and thus, you are not qualifed for the US citizenship application. If you are qualified for the US citizenship application, just go ahead to do it and your "后2年半大部分时间在中国" does not matter.
移民局会查出入境记录吗？
护照需要换本新的吗？
-Why?
谢谢指教哈。
