本人2008年4月拿到綠卡（起始日2008.4.12，雇主辦理的），一直在美國居住，2009年曾回國三周短期探親。
2012年3月底申請到白皮書（有效期至2014年3月），然後離開美國到北京居住至今。
今年夏季想要回美國入籍，請問白皮書期間可以申請入籍嗎？我的年限夠嗎？
-If you have stayed in China for > 6 months continuously, your physical presence continuity may be disrupted (depends on how you convince the IO); if you have stayed in China continuously for > one year, your physcial presence will be disrupted. If so, you can not be qualified for the US citizenship application until you stay in US for another 5-year term.
