美国入籍与 N-400U.S. naturalization and Form N-400
准备申请美国公民？先把资格看清楚Ready for citizenship? Start with eligibility.
持绿卡的年限、实际在美时间、旅行、税务和既往申请，都可能影响入籍。我们先帮你核对资格，再准备 N-400 和面试。Years as a resident, time in the U.S., travel, taxes, and earlier filings can affect naturalization. Review eligibility before preparing the N-400 and interview.
先看与你有关的重点Start with what matters for your case
居住与旅行Residence and travel
整理取得绿卡以来的住址和出入境记录，特别留意长期离境。绿卡有效，不等于入籍的居住要求一定满足。Map addresses and travel since residence began, especially long absences. A valid card does not establish naturalization residence eligibility.
N-400 与历史记录N-400 and earlier records
核对税务、婚姻、工作、组织经历和被捕／法院记录。表格回答要与真实经历及以前的申请一致，有差异就解释清楚。Review taxes, marriage, work, membership, and arrest or court records. Answers must reflect the facts and earlier filings; explain differences.
面试与后续Interview and next steps
准备适用的英语、公民知识及表格问答。是否有测试例外或便利安排，以及何时宣誓，要按个人条件和通知确认。Prepare the applicable English, civics, and application review. Test exceptions, accommodations, and the oath schedule depend on eligibility and notices.

N-400 与家庭规划N-400 and family planning从儿子入籍，到父母团聚From the son’s naturalization to family reunification
当时的情况The situation
本所先协助儿子办理 I-485 并取得绿卡，后来协助其 N-400 入籍申请获批。成为公民后，他希望为父母申请绿卡。The firm first helped the son obtain residence through I-485 and later approval of his N-400 naturalization application. After becoming a citizen, he sought residence for his parents.
我们怎样处理How we helped
我们继续办理父母的亲属移民，准备他们的背景说明和模拟面试，把入籍后的家庭团聚计划衔接起来。We went on to handle the parents’ family cases, background statements, and mock interviews, connecting naturalization with the family’s reunification plan.
结果与提醒Result and context
儿子入籍后，父母的 I-485 于 2026 年 8 月获批。为父母递交 I-130 的公民一般须年满 21 岁，父母能否在境内递交仍需另看资格。After the son naturalized, his parents’ I-485 cases were approved in August 2026. A citizen generally must be at least 21 to petition for parents; their adjustment eligibility requires separate review.

拿到绿卡几年可以申请入籍？How many years after a green card may I apply?
常见的是五年规则；符合与美国公民配偶相关条件的人，可能适用三年规则，但不只是“结婚三年”或“婚绿三年”。还要看配偶的公民年限、共同生活、连续居住、实际在美时间及其他条件。提前递交也有专门规则。The common route is the five-year rule. Certain spouses of U.S. citizens may qualify under the three-year rule, but three years of marriage or a marriage-based green card alone is not enough. Review the spouse’s citizenship, marital union, residence, physical presence, and other requirements. Early filing has separate rules.
经常出国，会影响入籍吗？Can frequent travel affect naturalization?
可能。要分别计算实际在美时间和连续居住，并查看每次离境多久。长期离境即使没有让绿卡失效，也可能影响入籍资格。请提供完整出入境日期，不要只用大概天数判断。It may. Physical presence and continuous residence are separate tests, and each absence matters. A long trip can affect naturalization even if residence has not been lost. Use complete travel dates rather than rough estimates.
合法领取福利，会直接影响入籍吗？Does lawful benefits use itself prevent naturalization?
合法领取福利本身，通常不是 N-400 的公共负担审查问题。但是否符合福利资格、申请时是否如实陈述，以及有无欠税或欺诈等，要分开看。不要因为担心而隐瞒真实情况。Lawful benefits use itself is generally not a public-charge test for N-400. Eligibility for benefits, truthful claims, and issues such as taxes or fraud require separate review. Do not hide facts out of concern.
没有犯罪记录，就一定符合良好品格要求吗？Does no criminal record establish good moral character?
不一定。税务、抚养义务、是否如实回答、违法投票或其他行为也可能有关。有被捕、法院、欠税等记录时，先准备完整材料；补救措施可能有帮助，但不能保证解决所有法律限制。Not necessarily. Taxes, support obligations, truthful answers, unlawful voting, and other conduct may matter. Gather complete arrest, court, or tax records when relevant. Corrective steps can help but do not guarantee that every legal bar is resolved.
EB-1／NIW 拿绿卡后转行，会影响入籍吗？Does a career change after EB-1 / NIW affect naturalization?
转行本身不等于失去资格，也没有必须一辈子做同一工作的要求。但审理时可能核对当初申请的真实性、获批后实际安排和时间线。应保留原计划及后来变化的记录，不宜简单保证“一定没有影响”。A career change does not itself establish ineligibility, and there is no lifetime requirement to keep one occupation. Review may still examine the original petition’s truthfulness, intent, later arrangements, and timing. Keep records of the plan and subsequent changes.
以前的组织或军队相关经历，还要说明吗？Must earlier membership or military-related history be disclosed?
按 N-400 的适用问题如实回答。移民局可能对原有移民资格和入籍条件分别核对；以前办绿卡时说明过，不代表这次可以省略。具体法律范围、期限和例外应单独评估。Answer the applicable N-400 questions truthfully. USCIS may review both earlier immigration eligibility and naturalization requirements. Prior disclosure does not mean the topic can be omitted now. Applicable scope, periods, and exceptions require separate review.
决定放弃绿卡后，I-407 能顺便解决签证或税务吗？Does I-407 resolve future visa or tax issues?
不能这样理解。I-407 是正式放弃永久居民身份的程序，决定前应了解移民和税务后果。它不保证以后获得旅游签证，也不会自动结束所有税务义务；必要时应同时咨询税务专业人士。No. I-407 records abandonment of permanent residence. Understand immigration and tax consequences before deciding. It does not guarantee a visitor visa or automatically end all tax obligations; obtain tax advice where needed.
