綠卡到手5年了。期間前2年半居住美國，後2年半大部分時間在中國。這種情況怎麽做可能性比較大轉公民？
-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 "後2年半大部分時間在中國" does not matter.
移民局會查出入境記錄嗎？
護照需要換本新的嗎？
-Why?
謝謝指教哈。
