因工作关系在接下来一年可能需要经常回国，所以想先做回美证的申请（但还是打算在这一年内在美国以外的时间少于6个月）。请问一年后入籍的时候，申请回美证（但不需使用的情况）是否会对入籍有影响呢 ？
-No, but if you stay outside US for > 180 days, it is possible that your physical resident continuity may be disrupted; and if > one year, it will be disrupted. Thus, your US citizenship have to wait for another 4 years from the date you come back and live in to US.
非常感谢！
