📚 Pre-Departure Travel Guide for Overseas Study and Work Internships | 海外教育或工作实习行前旅行指南
Going abroad for a degree, a summer programme, or a work internship is one of the most valuable investments a student can make. Yet the difference between a smooth landing and a chaotic first fortnight is rarely luck. It is almost always the preparation completed in the weeks before departure: the visa that was applied for early, the accommodation that was confirmed in writing, the bank card that was activated, the insurance policy that was actually read. This guide sets out a practical, checklist-driven approach to pre-departure travel, organised so that you can work through it in order and tick items off as you go. It is written for school leavers, undergraduates and interns heading to the UK, the US, Canada, Australia, Europe and Asia, and it assumes no prior experience of living abroad.
出国读学位、参加暑期项目或进行工作实习，是学生能做出的最有价值的投资之一。顺利落地与手忙脚乱的头两周之间的差别，很少来自运气，而几乎总是来自出发前几周的准备：提前申请的签证、书面确认的住宿、已激活的银行卡、真正读过的保险条款。本指南提供一套以清单为驱动的行前旅行实操方法，按可依次执行的顺序编排，便于逐项打勾完成。文章面向前往英国、美国、加拿大、澳大利亚、欧洲及亚洲的中学毕业生、本科生与实习生，并假设你此前没有任何海外生活经验。
1. The Pre-Departure Timeline | 行前准备时间线
The most common mistake is treating the flight date as the deadline. Visa appointments, accommodation contracts and enrolment confirmations all involve queues and processing times, and any one of them can fail. Work backwards from the departure date and give every task a buffer. A workable rule is to begin serious preparation 12 weeks before departure and to finish every irreversible task, such as the visa, the housing deposit and the tuition payment, at least 3 weeks before the flight.
最常见的错误是把航班日期当成截止日期。签证预约、住宿合同和入学确认都涉及排队与处理时间，任何一环都可能出问题。应当从出发日期倒推，为每项任务留出缓冲。一个可操作的规则是：在出发前12周开始认真准备，并在起飞前至少3周完成所有不可逆事项，例如签证、住宿押金和学费缴纳。
Preparation start date = Flight date − 84 days
Not all tasks carry the same risk. Anything that requires a third party to act, such as an embassy, a university, a landlord or a bank, must come first, because you cannot speed it up by working harder. Tasks that depend only on you, such as packing or downloading offline maps, can safely be left to the final week.
并非所有任务风险相同。任何需要第三方行动的事项，例如使馆、大学、房东或银行，都必须优先，因为你无法靠更努力来加快它。只取决于你自己的任务，例如打包或下载离线地图，可以放心留到最后一周。
| Time before departure | 行前时间 | Key actions | 关键任务 |
| T − 12 weeks | 出发前12周 | Visa application, passport renewal, housing search, health checks | 签证申请、护照换发、找房、体检 |
| T − 8 weeks | 出发前8周 | Confirm accommodation in writing, pay deposit, book flights | 书面确认住宿、支付押金、订机票 |
| T − 4 weeks | 出发前4周 | Insurance, bank cards, vaccinations, module or contract reading | 保险、银行卡、疫苗、课程或合同阅读 |
| T − 1 week | 出发前1周 | Packing, airport transfer booking, SIM or eSIM, document copies | 打包、预订接机、SIM 或 eSIM、证件复印 |
| T − 72 hours | 出发前72小时 | Online check-in, weight check, offline downloads, notify bank | 网上值机、称重、离线下载、通知银行 |
2. Documents, Visas and Immigration Compliance | 证件、签证与出入境合规
Your passport is the single most important object you will carry, and its validity rule is stricter than most students expect. Many countries require a passport valid for at least six months beyond your intended date of departure, not merely beyond your arrival. Check the requirement of your destination before you book anything, because a passport renewal can take several weeks in peak season.
护照是你随身携带的最重要物品，其有效期规定比大多数学生想象的更严格。许多国家要求护照在你的预计离境日期之后仍至少有六个月有效期，而不仅仅是在入境日期之后。在预订任何东西之前先查清目的地要求，因为在旺季护照换发可能耗时数周。
Required passport validity ≥ Intended stay + 6 months
The visa must match your purpose, not merely your destination. A student visa does not authorise paid work beyond stated limits, and an internship may require a specific permit, a sponsorship certificate, or a written agreement from the host organisation. Read the conditions attached to your visa: work hour caps, registration deadlines after arrival, and reporting obligations are the conditions most often breached by accident.
签证必须与你的目的相符，而不仅仅是与目的地相符。学生签证不允许超出规定范围的带薪工作，而实习可能需要特定许可、担保函或接收单位的书面协议。请阅读签证附加条件：工作时长上限、抵达后的登记期限以及报告义务，是最容易被无意违反的条件。
Build two copies of everything. Keep one digital set in cloud storage and one paper set in your hand luggage, never in the checked bag. The paper set should include the visa, the offer letter or enrolment confirmation, accommodation proof, insurance certificate and a bank statement. Border officers may ask to see any of them, and a phone with no battery is not evidence.
为所有材料准备两套副本。一套数字版存放在云端，一套纸质版放在随身行李中，绝不能放在托运箱里。纸质套装应包括签证、录取通知书或入学确认、住宿证明、保险凭证和银行流水。边检人员可能要求查看其中任何一份，而没电的手机不能作为证据。
- Passport and visa | 护照与签证
- Offer letter, CAS, I-20 or CoE | 录取通知书、CAS、I-20 或 CoE
- Accommodation contract or confirmation | 住宿合同或确认函
- Insurance certificate and policy number | 保险凭证与保单号
- Financial evidence and scholarship letter | 资金证明与奖学金函
- Vaccination or health certificate | 疫苗或健康证明
- Passport-sized photographs (6 or more) | 护照照片（6张以上）
3. Flights, Baggage and Airport Navigation | 机票、行李与机场流程
Book a student fare where one exists. Student fares often allow extra checked baggage and free date changes, which matters when a visa is delayed. Compare the total cost, not the ticket price: a cheap fare with one 23 kg bag can be more expensive than a slightly higher fare that includes two.
如有学生票价，请优先预订。学生票通常允许额外托运行李和免费改期，这在签证延误时非常重要。比较总成本，而不是票面价格：一张便宜但只含一件23公斤行李的票，可能比稍贵但含两件行李的票更昂贵。
Usable luggage = (Checked pieces × Checked weight) + Cabin weight
Connection time is where inexperienced travellers lose flights. A 60-minute connection at a large hub is not a real connection once immigration, a terminal change and a re-checked bag are involved. As a working minimum, allow at least 90 minutes for a domestic connection and at least 120 minutes for an international one, and considerably more if you must clear immigration and re-check baggage.
转机时间是新手最容易误机之处。在大型枢纽，一旦涉及边检、换航站楼和重新托运，60分钟转机并不现实。作为最低参考：国内转机至少预留90分钟，国际转机至少预留120分钟；如果必须过边检并重新托运行李，则要大幅增加。
On arrival, expect a fixed sequence: immigration and passport control, baggage claim, customs declaration, then ground transport. Have your address written down on paper, not only saved in a phone. If your host university offers an airport pickup service, use it for your first arrival, even if it costs a little more.
抵达后，通常会经历固定流程：边检与护照查验、提取行李、海关申报，然后转地面交通。请把住址写在纸上，不要只存在手机里。如果接收大学提供接机服务，第一次抵达时请使用它，即使费用略高。
4. Money, Banking and Cost of Living | 资金、银行与生活成本
Money problems cause more distress than academic ones in the first month. The standard advice is to arrive with three layers of access: a small amount of local cash for 3 to 7 days, an international card that works abroad, and a backup card kept in a different bag. Notify your bank of the travel dates so that a legitimate transaction is not blocked as fraud.
第一个月里，资金问题带来的困扰往往超过学业问题。标准建议是抵达时具备三层资金通道：足够3至7天使用的少量当地现金、一张可在境外使用的国际卡，以及放在另一个包里的备用卡。请提前告知银行你的出行日期，以免正常交易被当作欺诈而拦截。
Monthly budget = Rent + Food + Transport + Phone + Insurance + Miscellaneous
Always pay in the local currency when a card terminal offers a choice. Choosing to be charged in your home currency, sometimes labelled dynamic currency conversion, adds a hidden markup that is typically 3% to 5%. Over a full academic year this is a meaningful sum, and it buys you nothing.
当刷卡终端提供选择时，务必以当地货币结算。选择以本国货币结算（有时标注为动态货币兑换）会附加通常为3%至5%的隐性加价。在一整个学年中，这是一笔可观的金额，而你什么也没换到。
| Category | 类别 | Typical share | 通常占比 | Notes | 说明 |
| Rent and bills | 房租与账单 | 40% – 50% | Highest fixed cost | 最高的固定支出 |
| Food | 饮食 | 15% – 20% | Cooking reduces this sharply | 自己做饭可大幅降低 |
| Transport | 交通 | 5% – 10% | Student passes save more | 学生月票更省 |
| Phone and internet | 手机与网络 | 3% – 5% | SIM-only plans are cheapest | 纯 SIM 套餐最便宜 |
| Insurance and health | 保险与医疗 | 5% – 10% | Check what the university covers | 查清学校覆盖范围 |
| Miscellaneous and travel | 杂项与旅行 | 10% – 20% | The category that always overruns | 最容易超支的一项 |
5. Accommodation and Arrival Logistics | 住宿与抵达安排
Never pay a deposit for a room you have not seen, and never rent from someone who refuses a written contract. University halls are the safest first option: the contract is standard, the deposit is protected, and help is available on site. Private rentals are cheaper in some cities but place all the risk on you.
绝不要为没有亲眼见过的房间支付押金，也绝不要向拒绝签订书面合同的人租房。大学宿舍是第一个学年最安全的选择：合同标准、押金受保护、现场有支援。在一些城市私人租房更便宜，但全部风险由你承担。
Read the tenancy agreement for four specific things: the length of the fixed term, the notice period, who pays utilities, and the conditions under which the deposit is returned. A deposit is not a fee. In most jurisdictions it must be protected in a government-backed scheme and returned unless the landlord can prove damage.
租约要重点读四件事：固定期限长度、通知期、谁支付水电煤、押金退还条件。押金不是费用。在多数法域，押金必须存入政府认可的保障计划，除房东能证明损坏外应予退还。
Book temporary accommodation for your first 3 to 7 nights, even if your long-term room is confirmed. Delays happen, keys get collected late, and arriving at midnight with nowhere to sleep turns a minor problem into a crisis. Also confirm the practical details in writing: the check-in time, the person who will meet you, and the exact address including the postcode.
即使长期住所已确认，也请预订头3至7晚的临时住宿。延误时有发生，钥匙可能很晚才拿到，而半夜抵达却无处可睡会把小问题变成危机。同时以书面形式确认实务细节：入住时间、接待人，以及包含邮编的准确地址。
6. Health, Insurance and Safety | 健康、保险与安全
Health preparation is boring until it is urgent. Get any required vaccinations at least four weeks before departure, because some courses require multiple doses spaced over time. Carry a written summary of your medical history, prescriptions and allergies in English, and keep a copy in the cloud.
健康准备在紧急之前总是枯燥的。请在出发前至少四周完成所需疫苗接种，因为某些疫苗需要分多次、间隔数周注射。随身携带英文书写的病史、处方与过敏记录，并在云端保留一份副本。
Read the insurance policy rather than the summary. Check four numbers: the medical cover limit, the excess or deductible, whether pre-existing conditions are excluded, and whether the policy covers internships and unpaid placements as well as study. If your internship is arranged through a university, confirm in writing who insures you at the workplace, because employer liability cover and personal health cover are different things.
请阅读保险条款本身，而不是宣传摘要。重点核对四个数字：医疗保障额度、免赔额、既有疾病是否除外，以及保单是否同时覆盖实习与无薪岗位，而不只是学习。如果实习由大学安排，请书面确认工作场所由谁承保，因为雇主责任险与个人健康险是两回事。
Some medications that are legally available at home are controlled or banned elsewhere. Check the rules of your destination before you fly, carry prescription documentation, and keep medicines in original labelled packaging in hand luggage. Never place essential medication in a checked bag.
一些在本国合法的药物在别处属于管制或禁用。起飞前查清目的地规定，携带处方证明，并将药品放在随身行李中的原标签包装内。绝不要把必需药物放进托运箱。
7. Packing Smart: Climate, Culture and Essentials | 智慧打包：气候、文化与必备品
Pack for the climate you are moving to, not the climate you are leaving. Check the average temperature and rainfall for your destination months, then pack layers rather than bulky single-purpose items. A light waterproof shell plus two warm mid-layers outperforms one heavy coat in almost every temperate country.
按你要去的地区气候打包，而不是你离开的地区。查看目的地各月的平均气温与降水，然后带可叠穿的衣物，而不是笨重的单一用途物品。在几乎所有的温带国家，一件轻便防水外套加两件保暖中层，胜过一件厚重外套。
Power (W) = Voltage (V) × Current (A)
Check the voltage and plug type before buying adapters. Most of Europe runs at 220–240 V and North America at 120 V, so a device rated only for 120 V will be damaged by a 240 V socket without a converter, not merely an adapter. Laptops and phone chargers are usually dual-voltage and need only a plug adapter; hair dryers and kettles usually are not.
购买转换插头前先确认电压与插头类型。欧洲大部分地区为220–240伏，北美为120伏，因此仅标注120伏的设备插入240伏插座时，若无变压器就会损坏，而不仅是需要转换插头。笔记本电脑和手机充电器通常是宽电压，只需插头转换器；吹风机和电水壶通常不是。
| Category | 类别 | Essential | 必备 | Leave behind | 不必携带 |
| Documents | 证件 | Passport, visa, copies, photos | 护照、签证、复印件、照片 | Heavy folders of originals | 厚重的原件文件夹 |
| Clothing | 衣物 | Layers, one formal outfit | 可叠穿衣物、一套正装 | Full wardrobes for every season | 四季全套衣物 |
| Electronics | 电子设备 | Laptop, adapter, power bank | 电脑、转换插头、充电宝 | Large appliances | 大型家电 |
| Health | 健康用品 | Prescriptions, basic first aid | 处方药、基础急救包 | Bulk supplies for a year | 够用一年的囤货 |
| Culture | 文化用品 | Small gifts, dress-code items | 小礼物、符合着装规范的衣物 | Items that may breach customs rules | 可能违反海关规定的物品 |
8. Digital Readiness and Communication | 数字化准备与通讯
Assume you will lose internet access at the worst moment. Before you fly, download offline maps of your city, save the address of your accommodation and university in a notes app and on paper, and screenshot your booking references. Cloud backup your laptop and phone, and confirm that your two-factor authentication codes will still reach you when your home SIM card stops working.
请假设你会在最糟糕的时刻失去网络。起飞前，下载所在城市的离线地图，把住宿与学校的地址同时存入备忘录和纸上，并截图所有预订编号。对笔记本电脑和手机进行云端备份，并确认当本国 SIM 卡失效后，你的双因素验证码仍然能收到。
Time difference = Local time at destination − Local time at home
Decide your connectivity strategy before departure. A local SIM gives the best value and a local number, which many landlords and employers require, but needs a shop visit on arrival. An eSIM can be activated before you fly and works immediately, at a slightly higher cost. Running both, with an eSIM for the first week and a local SIM afterwards, is the most common practical solution.
