请教各位一下: 在申请批准N-470(Application to Preserve Residence for Naturalization Purpose) 的资格要求中有一项:"in most cases you must have been physically present and residing in the United States for an uninterrupted period, without any absences whatsoever, for at least one year after your admission as a lawful permanent resident before you can file a Form N-470".
请教一下:这里所指的"physically present and residing in the United States for an uninterrupted period, without any absences whatsoever, for at least one year after your admission as a lawful permanent resident" 是指拿到绿卡后第一年不离开美国否则就不能申请批准N-470， 还是指只要在有绿卡期间任何一段时间
内连续居住了一年以上((比如拿到绿卡后第一年曾短暂访问中国,但第二年和第三年一直没有离开美国因此连续在美国居住了一年以上)就可以满足此项申请N-470豁免的资格要求？
从字面上看, 我觉得这是指绿卡期间要连续居住了一年以上,而不是特别要求是在拿到绿卡后的第一年内不离开美国否则就不能申请批准N-470.请教各位的意见?
