作为国际学生入境美国，是一个既令人兴奋又有严格规定的过程。从获得正确签证到通过海关与边境保护局，每一步都需要细致准备。本指南分解了整个入境流程，提供实用建议，帮助你避免延误、顺利通过检查，平稳开启留学生活。
1. Pre-Departure Documentation Check | 出发前文件检查
Before you travel, confirm that you have all required documents in your carry-on bag — never place them in checked luggage. Essential items include a valid passport with a U.S. visa, the Form I-20 (for F-1 students) or DS-2019 (for J-1 students), the SEVIS fee payment receipt, financial evidence, and your university admission letter. If you are under 18, also carry a notarized parental consent form.
出发前，请确认将全部必备文件放入随身行李，切勿托运。必备材料包括：贴有美国签证的有效护照、I-20表格（F-1学生）或DS-2019表格（J-1学生）、SEVIS费用缴纳收据、资金证明以及大学录取通知书。未满18岁还需携带经公证的父母同意书。
- Valid passport with F-1/J-1 visa
- Original I-20 or DS-2019 signed by you and a DSO
- SEVIS I-901 fee receipt
- Financial support documents (bank statements, scholarship letters)
- Admission offer letter and any correspondence with the university
- 贴有F-1/J-1签证的有效护照
- 由本人和指定校方官员签字的I-20或DS-2019原件
- SEVIS I-901缴费收据
- 资金支持文件（银行对账单、奖学金信函）
- 录取通知书及与大学往来信件
2. Understanding Your Visa and I-20 | 了解你的签证和I-20表格
Your F-1 visa shows you are permitted to enter the U.S. for a full course of study, while the I-20 certifies your eligibility and contains your SEVIS ID. Make sure all biographical details match your passport exactly. If your I-20 has a travel signature on page 2, it must be less than one year old on the day you re-enter; for initial entry, signature validity is typically six months.
你的F-1签证表明你被允许入境进行全日制学习，而I-20表格证明你的资格并包含SEVIS ID。所有个人信息务必与护照完全一致。若I-20第2页有旅行签名，重新入境时该签名需在一年以内；首次入境通常要求签名在6个月内有效。
The visa may state ‘F-1’ and list your school’s name, but Customs and Border Protection (CBP) officers also verify your intent. They expect you to demonstrate nonimmigrant intent — plans to return home after completing your studies. Carrying evidence of ties to your home country (family, property, job offer upon return) is a sensible precaution.
签证上会标明’F-1’及学校名称，但海关与边境保护局官员还会核查你的入境意图。他们希望看到你展示非移民意图——即完成学业后回国的计划。随身携带证明与母国联系的证据（家庭、房产、毕业后工作邀约）是明智的预防措施。
3. SEVIS Fee Payment and Receipt | SEVIS费用缴纳与收据
All F-1 and J-1 applicants must pay the I-901 SEVIS fee before appearing at a U.S. port of entry, although it is generally paid before the visa interview. Bring a printed receipt or electronic copy showing payment confirmation. If you have changed status or transferred schools, your previous payment may still be valid; confirm with your DSO.
所有F-1和J-1申请人须在入境美国口岸前缴纳I-901 SEVIS费用，通常需在签证面谈前支付。请携带打印版收据或电子版缴费确认。如果你已变更身份或转学，先前的缴费可能仍然有效，可与指定校方官员确认。
You can pay online at fmjfee.com using a credit card, and print the receipt immediately. In some cases, third-party payment through Western Union is available. Retain the receipt — you will need it if asked by the consular officer or CBP.
可在 fmjfee.com 使用信用卡在线支付并立即打印收据。部分情况可通过西联汇款进行第三方付款。请保留收据——领事官员或海关可能要求出示。
4. Packing Essentials and Prohibited Items | 行李打包要点与违禁品
Packing wisely reduces stress at customs. Keep all liquid medications in their original containers with a prescription letter; do not carry large quantities of cash exceeding USD 10,000 without declaring it. Common prohibited items include fresh fruits, vegetables, meat products, plant seeds, and cultural artifacts. Electronic devices may be inspected, so back up sensitive data separately.
合理打包可以减轻海关压力。液体药品应保留在原包装并携带处方信；携带超过一万美元现金须申报，否则不可。常见的违禁品有新鲜水果、蔬菜、肉制品、植物种子及文物。电子设备可能被检查，建议将敏感数据单独备份。
| Allowed (carry-on) | Prohibited or restricted |
|---|---|
| Sealed snacks, prescription meds, laptops | Fresh produce, meat, soil, counterfeit goods |
| Hygiene products under 100 ml (in clear bag) | Drugs, weapons, certain traditional medicines |
请参考可携带与违禁品表格。
5. At the Airport: Check-in and Security | 在机场：值机与安检
Arrive at the airport at least three hours before an international flight. At check-in, present your passport, visa, and I-20. The airline may verify your SEVIS status using the Student and Exchange Visitor Information System (SEVIS) to confirm you are currently active. If any discrepancy arises, request to speak with a supervisor and have your DSO’s emergency contact ready.
国际航班建议提前至少三小时抵达机场。值机时出示护照、签证和I-20。航空公司可能通过SEVIS系统核实你的状态，确认状态为Active。若出现任何不一致，要求与主管沟通，并准备好指定校方官员的紧急联系电话。
Security screening requires removing shoes, belts, and electronics from bags. Place liquids in a transparent quart-sized bag. After security, proceed to your gate and stay near the boarding area. Boarding typically starts 45 minutes before departure. Keep your documents easily accessible, as gate agents may check them again.
安检需脱鞋、解下腰带并取出电子设备。液体装入透明夸脱大小的袋子。通过安检后前往登机口并在附近等候。通常起飞前45分钟开始登机。保持证件随时可取，登机口工作人员可能再次查验。
6. On Arrival: U.S. Customs and Border Protection (CBP) | 抵达时：美国海关与边境保护局
Upon landing, follow signs for ‘Non-U.S. Citizens’ or ‘Visitor’ lines. Do not enter the Global Entry or U.S. citizen line unless you are eligible. Present your passport, visa, I-20, and customs declaration form (if issued on the aircraft). The CBP officer will scan your fingerprints and take a photograph. Answer questions clearly and confidently.
下机后，按照’非美国公民’或’访客’通道指示排队。除非符合资格，切勿进入全球入境或美国公民通道。出示护照、签证、I-20以及海关申报表（机上发放）。海关官员会扫描指纹并拍照。回答问题要清晰自信。
Common questions include: ‘What is the purpose of your visit?’, ‘Where will you be studying?’, ‘How long do you intend to stay?’, and ‘Do you have enough funds?’ Always answer truthfully. If the officer seems confused about your program, you may show the admission letter or financial documents. They may stamp your passport and write ‘D/S’ (Duration of Status) on your admission stamp.
常见问题包括：’你来访的目的是什么？’、’你将去哪里学习？’、’打算停留多久？’、’资金是否充足？’ 务必如实回答。若官员对你的项目有疑问，可出示录取信或资金证明。他们可能在护照上盖章并标注’D/S’（Status持续期间）。
7. Secondary Inspection and Common Questions | 二次检查与常见问题
In some cases, CBP may refer you to secondary inspection for further questioning. This is not necessarily suspicious — it can happen for address verification, I-20 validation, or random checks. Remain calm and cooperative. You may be asked to open your luggage and explain the content of electronic devices. Do not lie or conceal information, as that can lead to denial of entry.
某些情况下，海关可能将你转至二次检查区进一步询问。这不代表有嫌疑——可能是核实地址、验证I-20或随机抽查。保持冷静并配合。可能要求开箱检查并解释电子设备内容。切勿撒谎或隐瞒信息，这可能导致拒绝入境。
If you have any pre-existing conditions or medications, declare them proactively. If you carry more than USD 10,000 in cash or monetary instruments, you must file a FinCEN Form 105. Failure to declare may result in seizure of funds.
若有任何既往病史或药品，主动申报。若携带超过一万美元现金或货币工具，须填写FinCEN 105表格。不申报可能导致资金被没收。
8. Baggage Claim and Customs Declaration | 行李提取与海关申报
After primary inspection, proceed to the baggage claim area. Collect your checked luggage and check your bags’ condition. If anything is damaged or missing, report to your airline immediately. Then head toward the customs exit, where you may be asked to submit your customs declaration form. Most airports have green ‘Nothing to Declare’ and red ‘Goods to Declare’ channels.
初步检查后前往行李领取处。提取托运行李并检查箱包状态。如有损坏或丢失，立即向航空公司申报。然后前往海关出口，可能需递交海关申报表。多数机场设有绿色’无需申报’和红色’有物品申报’通道。
Remember that even duty-free items must be declared if they exceed exemption limits. Students are not exempt from agricultural inspection — undeclared food items can incur fines up to USD 1,000. If in doubt, declare. Honesty prevents future complications.
注意，即使免税品超出了免税额度也须申报。学生并不免于农业检查——未申报的食物可能被罚高达1000美元。如有疑问，请申报。诚实可避免将来麻烦。
9. Connecting Flights or Ground Transportation | 转机或地面交通
If you have an onward domestic connection, re-check your luggage (most airports have special drop-off points after customs). Follow signs for ‘Connecting Flights’ and go through TSA security again. Allow ample time — at least 3 hours for the first U.S. entry, as processing can be lengthy. Keep your boarding pass and ID ready.
若有后续境内转机，需重新办理行李托运（多数机场在海关后有专门行李投放点）。按’转机航班’指示牌走，并再次通过TSA安检。预留充足时间——首次入境建议至少3小时，因为入关手续可能耗时。准备好登机牌与证件。
If your final destination is the arrival city, arrange shuttle, taxi, or ride-hailing services. Many universities offer free pickup through international student services; book in advance. Avoid unlicensed taxis and always agree on fare before boarding or confirm the price via app.
若最终目的地即为抵达城市，可安排班车、出租车或网约车。许多大学通过国际学生服务提供免费接机，请提前预定。勿乘坐黑车，上车前议价或通过应用程序确认价格。
10. Reporting to Your School and SEVIS Activation | 向学校报到和SEVIS激活
Once you arrive at your university, report to the international student office (or your DSO) within the date specified on your I-20, usually by the program start date. The DSO will photocopy your passport, I-20, and I-94 record, then activate your SEVIS record. This step is critical; failing to report can result in termination of your F-1 status.
抵达大学后，须在I-20上注明的日期内，通常是项目开始日期前向国际学生办公室（或指定校方官员）报到。工作人员会复印护照、I-20及I-94记录，然后激活你的SEVIS档案。这一步至关重要；未报到可能导致F-1身份被终止。
Download your I-94 record from the CBP website (i94.cbp.dhs.gov) immediately after entry. Check that the ‘Admit Until Date’ says ‘D/S’ and that all biographical details are correct. If any error appears, request correction within 10 days.
入境后立即从CBP官网（i94.cbp.dhs.gov）下载I-94记录。核对’获准逗留至’是否为’D/S’，并且所有个人信息无误。如有任何错误，须在10天内申请更正。
11. Post-Entry Tips and Cultural Adjustment | 入境后建议与文化适应
Once settled, open a U.S. bank account, obtain a local SIM card, and attend orientation sessions. Keep your passport, I-20, and I-94 in a secure yet accessible location. Do not work off-campus without proper authorization; on-campus employment is usually allowed up to 20 hours per week while school is in session.
安顿后，开设美国银行账户、获取本地手机卡并参加迎新活动。将护照、I-20和I-94保存在安全但易取的地方。未经授权切勿校外打工；学期期间校内工作通常允许每周不超过20小时。
Adapting to a new academic environment takes time. Observe cultural norms, reach out to international student clubs, and don’t hesitate to use campus counseling services if you feel overwhelmed. Maintaining full-time enrollment is mandatory — dropping below a full course load without prior DSO approval violates your status.
适应新的学术环境需要时间。尊重文化规范，积极参加国际学生社团，若感到压力过大，不要犹豫使用校园心理咨询服务。必须保持全日制注册——未经DSO事先批准降低学分负荷将违反身份规定。
