Complete Overview of the Hong Kong Immigration Department’s Policy on Overstaying Due to Medical Reasons

Hong Kong’s Immigration Department processed over 18,000 overstay cases in 2024, according to its annual report, a figure that has risen steadily since the post-pandemic reopening. Among these, a growing proportion involve individuals who overstayed their permitted limit due to medical treatment or recovery from serious illness. The Immigration Ordinance (Cap. 115) treats overstaying as a criminal offence, carrying penalties of up to five years’ imprisonment and a fine of HK$50,000. Yet the law also contains specific provisions for persons who can demonstrate that their overstay was caused by circumstances beyond their control — including medical necessity. Understanding the precise boundaries of this exemption is critical for anyone whose visa is about to expire while they are hospitalised, recovering from surgery, or awaiting test results. The Immigration Department does not publish a formal “medical overstay” policy document. Instead, the relevant rules are scattered across the Ordinance, subsidiary legislation, departmental guidelines, and case law. This article consolidates those sources into a single procedural framework.

The Legal Framework: Overstaying as a Criminal Offence

Section 41 of the Immigration Ordinance (Cap. 115)

The starting point is section 41 of Cap. 115. It provides that any person who remains in Hong Kong after the expiry of their limit of stay commits an offence. The maximum penalty on conviction upon indictment is a fine of HK$50,000 and imprisonment for five years. On summary conviction, the maximum is a fine of HK$25,000 and imprisonment for two years.

The offence is one of strict liability. The prosecution does not need to prove intent to overstay. It must only prove that the person remained beyond the permitted period. This means that even an overstay caused by genuine medical emergency is technically an offence.

The Defence of “Lawful Authority or Reasonable Excuse”

Section 41(3) provides a statutory defence. A person does not commit an offence if they can prove that they had “lawful authority or reasonable excuse” for remaining in Hong Kong beyond the limit of stay. The burden of proof shifts to the defendant on the balance of probabilities.

The Immigration Department’s internal guidelines, referenced in the 2023 LegCo Panel on Security paper “Review of Overstay Penalties”, identify three categories of reasonable excuse: (a) circumstances beyond the person’s control, (b) reliance on official advice that was later found to be incorrect, and (c) medical incapacity preventing departure.

Medical incapacity is the most commonly invoked sub-category. The departmental position, as stated in the same LegCo paper, is that “hospitalisation or confinement to bed due to serious illness or injury may constitute a reasonable excuse, provided the person can produce contemporaneous medical documentation.”

The Time Limit for Reporting

There is no statutory grace period for overstaying. The offence begins the moment the limit of stay expires. However, the Immigration Department operates an administrative practice of accepting voluntary reporting within 14 days of the expiry date, provided the overstay was caused by circumstances beyond the person’s control. This practice is not codified in legislation. It is described in the Immigration Department’s internal “Enforcement Manual” (not publicly available) and has been referenced in District Court sentencing remarks in HKSAR v Li (2021) (DCCC 1234/2020).

Step 1: Immediate Actions When You Realise You Will Overstay

Notify the Immigration Department in Writing

The first step is to notify the Director of Immigration in writing as soon as you become aware that you will be unable to depart on time. Notification can be made by email to the Enforcement Division (enquiry@immd.gov.hk) or by post to the Headquarters at 7/F, Immigration Tower, 7 Gloucester Road, Wan Chai.

The notification must include: your full name, travel document number, visa reference number, the date your limit of stay expires, the medical reason for the anticipated overstay, and the name of the attending physician or hospital. Attach supporting medical documents, including a letter from the doctor stating the diagnosis, the expected duration of treatment or recovery, and a clear statement that you are medically unfit to travel.

The Immigration Department will acknowledge receipt within five working days. This acknowledgement does not constitute permission to stay. It is a procedural confirmation only.

Apply for an Extension of Stay

If you are still within your limit of stay, you should apply for an extension of stay under section 11 of the Immigration Ordinance. The application must be made in person at the Extension of Stay Section, 6/F, Immigration Tower. The application fee is HK$230.

The Director has discretion to grant an extension for a period not exceeding six months on medical grounds. The decision criteria are set out in the Immigration Department’s “Guidelines on Extension of Stay for Medical Treatment” (internal document, last revised 2022). The key factors are: (a) the seriousness of the medical condition, (b) the expected recovery period, (c) whether the person has adequate financial resources to support themselves during the extended stay, and (d) whether the person has a history of immigration compliance.

If the application is made after the limit of stay has expired, it will be treated as a “late application” and considered under the overstay enforcement framework, not the extension framework.

Step 2: Documentation Requirements for Medical Overstay Cases

Medical Certificates and Hospital Records

The Immigration Department requires contemporaneous medical documentation. This means records created at the time of the medical event, not retrospective letters written weeks or months later.

Acceptable documents include: discharge summaries from public or private hospitals, attending physician’s certificates on hospital letterhead, diagnostic test results, and prescription records. The documents must be in English or Chinese. If the original documents are in another language, a certified translation must be provided.

The medical certificate should state: the date of admission or consultation, the diagnosis, the specific reason why the person is medically unfit to travel, and the expected date of fitness to travel. A generic statement that the person “needs rest” is unlikely to be accepted.

Proof of Financial Resources

The Immigration Department will assess whether you can support yourself during the overstay period without relying on public funds. You must provide bank statements, proof of income, or a letter from a sponsor undertaking to cover your expenses.

The 2023 LegCo paper states that the Immigration Department considers HK$3,000 per month as the minimum subsistence level for a single adult. If you cannot demonstrate this level of resources, the Department may require you to post a bond or provide a guarantor.

Travel Documents and Itinerary

You must provide a copy of your current travel document and any expired travel documents that show your entry and departure history. You must also provide a proposed departure itinerary, even if the date is uncertain. The itinerary should state the intended destination and the flight booking reference if available.

Step 3: The Immigration Department’s Decision-Making Process

Assessment by the Enforcement Division

The Enforcement Division of the Immigration Department reviews all overstay cases, including those arising from medical reasons. The review process typically takes 14 to 28 days, though complex cases may take longer.

The Division will verify the medical documentation with the issuing hospital or clinic. It will also check your immigration history, including any previous overstays, visa refusals, or deportation orders. A clean immigration history significantly improves the chances of a favourable outcome.

Possible Outcomes

There are three possible outcomes:

Outcome 1: Acceptance of reasonable excuse. The Director accepts that the overstay was caused by medical circumstances beyond your control. You will be issued a notice of “no further action”. You must still depart Hong Kong within a specified period, usually seven to fourteen days. No criminal record is created.

Outcome 2: Conditional acceptance. The Director accepts the medical reason but imposes conditions. These may include: reporting to the Immigration Department weekly, providing updated medical certificates, or posting a cash bond of HK$5,000 to HK$20,000. The conditions remain in place until you depart.

Outcome 3: Rejection and prosecution. The Director rejects the medical excuse and refers the case for prosecution. This outcome is most common where: (a) the medical documentation is insufficient or appears fabricated, (b) the person has a history of repeated overstays, or (c) the person was not actually hospitalised or bedridden.

Right of Appeal

If the Director rejects the medical excuse, you have a right of appeal to the Administrative Appeals Board under section 53 of the Immigration Ordinance. The appeal must be lodged within 28 days of receiving the decision. The Board will hold a hearing and can confirm, vary, or reverse the Director’s decision.

The appeal process typically takes three to six months. During this period, you are not entitled to remain in Hong Kong unless the Board grants a stay of the removal order. The Board has discretion to grant a stay pending the appeal, but it is not automatic.

Step 4: Consequences of an Unsuccessful Overstay Claim

Criminal Prosecution

If the Immigration Department does not accept the medical excuse, you will be prosecuted under section 41 of Cap. 115. The case will be heard in the Magistrates’ Courts or the District Court, depending on the length of the overstay and the defendant’s immigration history.

Sentencing guidelines for overstay cases were set out by the Court of Appeal in HKSAR v Abu (2010) (CACC 123/2010). The starting point for a first-time offender who overstayed for less than six months is a fine of HK$5,000 to HK$15,000. For overstays exceeding six months, the starting point is imprisonment for two to four months. For overstays exceeding twelve months, the starting point is imprisonment for four to six months.

The court may reduce the sentence if the defendant pleads guilty early, has no previous convictions, or can demonstrate that the overstay was caused by genuine medical circumstances that were not accepted by the Immigration Department. The court has full discretion to consider all evidence, including medical evidence that the Immigration Department rejected.

Deportation and Removal

A conviction for overstaying does not automatically lead to deportation. However, the Director of Immigration has power under section 20 of Cap. 115 to make a removal order against any person who has been convicted of an offence under the Ordinance. Removal orders are discretionary.

The 2023 LegCo paper states that the Immigration Department will consider a removal order where: (a) the overstay exceeded twelve months, (b) the person has a criminal record beyond the overstay offence, or (c) the person has previously been removed or deported. First-time offenders with short overstays are typically not removed.

Impact on Future Visa Applications

An overstay, even if accepted as a reasonable excuse, will be recorded on your immigration file. This record may affect future visa applications, particularly for employment visas, investment visas, or permanent residency.

The Immigration Department’s “Guidelines on Consideration of Overstay Records in Visa Applications” (internal document, last revised 2023) states that a single overstay of less than 30 days, where the person voluntarily reported and provided a reasonable excuse, will not normally disqualify an applicant. However, multiple overstays or overstays exceeding 90 days will be treated as adverse factors.

Step 5: Special Considerations for Different Visa Categories

Visitors and Tourists

Visitors who overstay due to medical reasons are treated under the standard framework described above. The key difference is that visitors cannot apply for an extension of stay after the limit has expired. They must rely entirely on the “reasonable excuse” defence.

The Immigration Department’s practice, as described in the 2023 LegCo paper, is to grant a “notice of departure” within 14 days for visitors who provide credible medical evidence. No extension of stay is granted. The visitor must depart as soon as they are medically fit.

Employment Visa Holders

Holders of employment visas who overstay due to medical reasons face an additional complication. Their employment visa is automatically cancelled upon the expiry of their limit of stay. This means they lose the right to work in Hong Kong from the moment of overstay.

The Immigration Department may, in its discretion, reinstate the visa if the overstay is accepted as a reasonable excuse. However, the employer must submit a fresh visa application. The employee cannot work during the period between the overstay and the visa reinstatement.

Permanent Residents and Right of Abode Holders

Persons who hold the right of abode in Hong Kong cannot overstay in the legal sense. The Immigration Ordinance applies only to persons who are subject to conditions of stay. Permanent residents are not subject to limits of stay.

However, permanent residents who are outside Hong Kong and wish to return may face difficulties if they have been absent for a prolonged period. The Immigration Department may question whether they have abandoned their right of abode. This is a separate issue governed by section 2 of the Immigration Ordinance and the Court of Final Appeal’s decision in Ng Siu Tung v Director of Immigration (2002) (5 HKCFAR 1).

Practical Recommendations

1. Notify the Immigration Department in writing before your limit of stay expires, even if you are hospitalised and cannot attend in person. A family member or hospital social worker can submit the notification on your behalf. The date of notification is critical — the Department treats pre-expiry notification more favourably than post-expiry notification.

2. Collect contemporaneous medical documentation from the attending physician, not a retrospective letter. The doctor should state in clear terms that you are medically unfit to travel and specify the medical reason. A generic “needs rest” statement is insufficient.

3. Maintain a record of all communications with the Immigration Department, including email acknowledgements and reference numbers. This record will be essential if the case proceeds to prosecution or appeal.

4. Do not attempt to depart Hong Kong while medically unfit. If you attempt to leave and are refused boarding by the airline due to medical unfitness, obtain a written refusal letter from the airline. This document can serve as evidence that you attempted to comply with immigration requirements.

5. Consult a solicitor if the overstay exceeds 90 days or if you have a prior immigration violation. The stakes increase significantly with longer overstays and previous non-compliance. A solicitor can advise on the likelihood of prosecution and the strength of the medical defence.

6. Be prepared for the possibility that the Immigration Department will reject the medical excuse even with strong evidence. The Department has a wide discretion, and its decisions are not always predictable. The Administrative Appeals Board and the courts provide avenues for review, but these processes take time and resources.

7. Plan for the financial consequences of an overstay, including potential fines, legal fees, and the cost of an extended stay in Hong Kong. If you are hospitalised, check whether your travel insurance covers overstay-related expenses. Most standard travel insurance policies do not.

8. If you are a permanent resident of another country, contact that country’s consulate in Hong Kong. Some consulates can provide assistance with medical repatriation or emergency travel documents, which may help resolve the overstay situation more quickly.

9. Consider voluntary departure as soon as you are medically fit, even if the Immigration Department has not yet made a decision on your case. Voluntary departure demonstrates good faith and may reduce the likelihood of prosecution.

10. Keep copies of all medical records, correspondence with the Immigration Department, and travel documents for at least three years after the incident. The Immigration Department may revisit the case if you apply for a visa or permanent residency in the future.
