This article provides a comprehensive comparison of student visa frameworks across five leading English-speaking study destinations: the United States, the United Kingdom, Canada, Australia and New Zealand. By examining visa categories, financial requirements, work rights, post-graduation pathways and recent policy shifts, students and advisors can make informed, strategic decisions.

在一个日益流动的世界，选择留学目的地早已不只看大学排名和课程内容。移民政策、工作权利和毕业后机会已成为国际学生的决定性因素。本文对美国、英国、加拿大、澳大利亚和新西兰这五个主流英语留学国家的学生签证框架进行了全面对比。通过分析签证类别、资金要求、工作权利、毕业后路径以及最新政策变化，学生和顾问可以做出明智的战略性决定。

1. Visa Categories: An Overview | 签证类别概览

The United States issues the F-1 visa for academic students and the M-1 for vocational study, with the F-1 being the primary route for degree-seeking applicants. The United Kingdom operates a single Student visa under the Student Route, which replaced the former Tier 4 system. Canada does not issue a student visa in the passport but grants a study permit, often accompanied by a visitor visa or an electronic travel authorisation (eTA) for entry. Australia uses the Subclass 500 Student visa for all full-time registered courses, while New Zealand provides a Fee Paying Student Visa for international learners.

美国为学术类学生签发 F-1 签证，职业类学习对应 M-1 签证，F-1 是攻读学位的主要渠道。英国在“学生路径”下运营统一的学生签证，取代了过去的 Tier 4 体系。加拿大并不在护照上签发学生签证，而是发放学习许可，入境时通常还需持有访问签证或电子旅行许可(eTA)。澳大利亚对所有全日制注册课程使用 500 类学生签证，新西兰则为国际学生提供付费学生签证。

2. Key Eligibility Requirements | 关键资格要求

All five countries require a confirmed offer of enrolment from a recognised institution. The US requires the Designated School Official to issue a Form I-20; the UK needs a Confirmation of Acceptance for Studies (CAS); Canada requires a letter of acceptance from a designated learning institution (DLI); Australia calls for a Confirmation of Enrolment (CoE); and New Zealand necessitates an offer of place from an approved education provider. Applicants must also demonstrate that they are genuine temporary entrants and intend to comply with visa conditions.

五个国家都要求申请人获得认可院校的录取通知书。美国需要学校指定官员签发 I-20 表格，英国需要录取确认函(CAS)，加拿大需要指定学习机构(DLI)的录取通知书，澳大利亚要求注册确认函(CoE)，新西兰则需要经批准的教育机构提供的录取通知。申请人还必须证明自己是真实的短期入境者，并打算遵守签证条款。

3. Financial Evidence | 资金证明

Financial requirements vary significantly. For a US F-1 visa, applicants must prove they can cover the estimated cost of the first year of study, with the amount set by the institution and stated on the I-20. The UK sets clear maintenance thresholds: for courses in London, GBP 1,334 per month for living costs; outside London, GBP 1,023 per month, up to a maximum of nine months. Canada requires proof of tuition fees plus CAD 10,000 per year for living expenses (CAD 11,000 for Quebec). Australia stipulates that the primary applicant has access to at least AUD 21,041 per year for living costs. New Zealand requires NZD 15,000 per year (or NZD 1,250 per month) if the programme is longer than 36 weeks.

资金要求差异很大。申请美国 F-1 签证时，申请人须证明有能力支付第一年的预估费用，金额由院校确定并写在 I-20 上。英国设定了明确的生活费门槛：在伦敦学习每月需 1,334 英镑，伦敦以外地区每月 1,023 英镑，最多按九个月计算。加拿大要求提供学费外加每年 10,000 加元生活费（魁北克 11,000 加元）。澳大利亚规定主申请人每年至少需有 21,041 澳元生活费。新西兰则要求若课程超过 36 周，每年需 15,000 新西兰元（或每月 1,250 新西兰元）。

4. English Language Proficiency | 英语语言能力

English language testing policies intersect with both institutional admission and visa requirements. The US leaves language proficiency largely to the admitting institution, though consular officers may assess English ability during the interview. The UK requires a Secure English Language Test (SELT) such as IELTS for UKVI, with the level matching the course requirements. Canada’s study permit does not generally mandate a language score, but the Student Direct Stream (SDS) for faster processing requires IELTS 6.0. Australia requires evidence of English proficiency at least equivalent to IELTS 5.5 for visa purposes, while New Zealand similarly expects a minimum IELTS score of 5.5 (with some exceptions).

英语测试政策涉及院校录取和签证要求。美国主要由录取院校决定语言水平，签证官在面谈时也可能评估英语能力。英国要求提供经批准的安全英语语言测试(SELT)成绩，如 UKVI 雅思，成绩需达到课程要求。加拿大学习许可通常不强制的语言分数，但通过学生直入计划(SDS)快速审理需要雅思 6.0。澳大利亚为签证目的要求英语能力至少相当于雅思 5.5，新西兰同样要求雅思最低 5.5 分（部分情况例外）。

5. Work Entitlements During Study | 学习期间工作权利

On-campus work is typically permissible, but off-campus employment rules vary. In the US, F-1 students may work on campus up to 20 hours per week during term, but off-campus work requires specific authorisation via Curricular Practical Training (CPT) or Optional Practical Training (OPT). The UK permits degree-level students to work up to 20 hours per week during term time and full-time during holidays. Canada allows students to work off campus up to 20 hours per week during academic sessions, with full-time permitted during scheduled breaks. Australia allows 48 hours per fortnight during study periods, with unlimited hours during holidays. New Zealand permits 20 hours per week during term and full-time during holidays; research master’s and PhD students have unlimited work rights.

校内工作通常允许，但校外就业规则各异。美国 F-1 学生学期中校内工作可每周最多 20 小时，校外工作需通过课程实习培训(CPT)或选择性实习培训(OPT)获得特别授权。英国允许学位课程学生学期中每周工作 20 小时，假期可全职。加拿大允许学生学期中校外工作每周最多 20 小时，规定假期可全职。澳大利亚允许学习期间每两周工作 48 小时，假期无限制。新西兰允许学期中每周 20 小时、假期全职；研究型硕士和博士生则无工作时间限制。

6. Post-Study Work Visas | 毕业后工作签证

Post-study work options have become one of the most heavily weighted factors for international students. The US offers Optional Practical Training (OPT) for 12 months, with a 24-month STEM extension, though the visa remains tied to the F-1 and the employer. The UK Graduate Route provides an unsponsored 2-year stay for bachelor’s and master’s graduates (3 years for PhD). Canada’s Post-Graduation Work Permit (PGWP) can last between 8 months and 3 years depending on the length of the programme, and it is an open work permit. Australia’s Temporary Graduate visa (subclass 485) grants 2 years for taught degrees, 3 for research master’s and up to 4 for PhD, with additional time for regional study. New Zealand’s Post-study work visa offers up to 3 years open work rights for Level 7 bachelor’s or higher qualifications.

毕业后工作选项已成为国际学生最看重的因素之一。美国提供可选实习培训(OPT)12 个月，STEM 领域可延长 24 个月，但签证仍与 F-1 身份和雇主挂钩。英国毕业生路径为学士和硕士毕业生提供 2 年无雇主担保的居留期（博士 3 年）。加拿大的毕业后工作许可(PGWP)根据课程长度持续 8 个月到 3 年不等，属于开放工签。澳大利亚临时毕业生签证（485 类）对授课型学位提供 2 年，研究型硕士 3 年，博士最长 4 年，偏远地区学习另有额外时间。新西兰毕业后工作签证对 7 级学士及以上学历提供最长 3 年开放工作权利。

7. Bringing Dependants | 家属陪同

Rules on accompanying family members differ substantially. US F-2 dependants cannot work or study full-time, and children may only attend K-12. The UK introduced a major change in January 2024: most taught master’s students can no longer bring dependants, though research master’s and PhD students may still do so. Canada allows spouses or common-law partners to apply for an open work permit if the student is enrolled in a master’s, doctoral or professional degree programme; otherwise work rights are restricted. Australia permits family members on a Subclass 500 subsequent entrant visa, and the partner generally has unrestricted work rights. New Zealand enables partners of students studying in areas of long-term skill shortage or at postgraduate level to obtain open work visas.

关于随行家属的规定差异很大。美国 F-2 家属不能工作或全职学习，子女只能就读 K-12。英国于 2024 年 1 月实施重大变更：大多数授课型硕士学生不能再携带家属，但研究型硕士和博士生仍可携带。加拿大允许配偶或同居伴侣申请开放工签，前提是学生就读硕士、博士或专业学位课程，其他情况下工作权利受限。澳大利亚允许家属通过 500 类后续入境签证随行，配偶通常拥有不受限制的工作权利。新西兰让在长期技能短缺领域学习或攻读研究生课程的学生配偶可以获得开放工签。

8. Health and Character Checks | 健康与品行检查

All five countries require medical examinations, often including a chest X-ray for tuberculosis, and police clearance certificates for stays longer than six months. The US generally requires a medical exam and vaccinations through an approved panel physician. The UK mandates a tuberculosis test for applicants from certain countries if staying over six months. Canada requires an upfront immigration medical exam (IME). Australia and New Zealand both have strict health requirements to protect public health and avoid excessive demand on health services, typically involving a full medical check-up and chest X-ray.

五个国家都要求体检，通常包括胸部 X 光以排查结核病，并在停留超过六个月时提供无犯罪证明。美国一般要求通过指定体检医生进行健康检查和疫苗接种。英国规定来自特定国家的申请人若停留超过六个月需进行结核病测试。加拿大要求预先进行移民体检(IME)。澳大利亚和新西兰都有严格的健康要求，以保护公共卫生并避免给健康服务带来过大负担，通常包括全面体检和胸部 X 光。

9. Recent Policy Updates | 最新政策动态

The international education landscape is experiencing rapid regulatory changes. The US has maintained OPT and STEM extensions but faces ongoing discussions about H1-B caps. The UK’s Graduate Route is under review, and the dependant ban for taught master’s students took effect in January 2024. Canada capped study permit approvals in 2024-2025, adjusted post-graduation work permit eligibility to exclude some college-private partnerships, and raised financial proof requirements. Australia increased the English requirement for the 485 visa and announced an age limit reduction to 35 (with transitional provisions), plus directed migration incentives towards regional areas. New Zealand has streamlined pathways but keeps inflation-adjusted financial thresholds under review.
