Why Nobody Warns You: Providers Own Completion, Not Consistency
One sentence explains all six: a provider completes the matter handed to them using the documents handed to them, and nobody is accountable for whether your four sets of records agree. Almost everything that surfaces later is a consistency problem.
You carry four independent record sets: the immigration record (visa, registration card, entry and exit history, reporting), the labour record (the employer and job title on your work permit), the tax and social security record (declared basis, contribution months) and the company's internal record (contract, grade, pay structure, address). Day to day, none of them looks at the others. They are read side by side at exactly three moments: renewal, a change of status, and being asked to explain something at the border.
Three features of assignment make this worse:
- You are not the applicant. The employer applies and you benefit. HR assembles the file, you may never have read it, and so you cannot notice where it diverges from fact.
- The people handling it rotate. Over a three-year posting, two HR handovers and a change of provider is normal. What the previous holder knew, the next one does not — while your file does not reset when the handler changes.
- Nobody owns the whole of you. HR owns onboarding and employment, the provider owns one application, finance owns the monthly payroll. Exactly one person has the full picture, and that is you.
Each of the six below follows the same template: what it looks like now (fine), when it surfaces, and the ten-minute check you can do today. Fixed annual actions are elsewhere — see the annual cycle — as is first-year setup, in your first year on assignment. None of the six is difficult on its own, and none of them costs much to fix in the year it arises. What makes them expensive is time: each one sits quietly until a filing forces the records to be read together, and by then the cheap remedy has usually expired along with the people who could have confirmed what happened. So read this as a list of ten-minute checks rather than a list of problems, and run them in the same sitting once a year.
Gap One: You Have Never Seen Your Own Documents, or Your Current Status
This is the most common and most fundamental gap for assignees — passport in the company safe, registration card in an HR drawer, and you do not even hold the reference number of any approval. It is not itself a breach, but it makes the other five gaps invisible to you.
What it looks like now: entirely normal. You work, you get paid, nobody has ever asked you for a document. Company custody may even feel safer than carrying things around.
When it surfaces: four moments. Booking business travel; opening a bank facility or doing anything that needs identity verification; being asked for supporting documents mid-renewal; and worst, being asked to produce something at an airport or a routine check when you hold nothing at all. On being pulled aside on entry, see what secondary inspection involves.
Company custody is not the problem; the absence of a backup is. Central custody is a legitimate arrangement and many roles need it. The real issue is holding no copy and no reference number, so that every situation requiring verification waits for HR office hours and for one particular person to reply — while urgent situations happen at night and at weekends.
Today's check, ten minutes:
- Obtain and keep colour scans of four things: passport bio and visa pages, the work permit, both sides of the registration card, and the reference number of every approval.
- Store two copies: one in your own cloud account (not a company account) and one offline on your phone or a drive.
- Verify four fields on the scans: name spelling, passport number, employer name, job title. Raise any mismatch this year.
- Write the four expiry dates — permit, card, visa, passport — on one sheet.
One adjacent but categorically different issue: if the company on your work permit is not the entity that actually pays you and at whose premises you actually work, that is not a records mismatch but a different order of risk, described in the risks of a permit held through an unrelated company. In that situation the checks above become urgent rather than merely prudent.
Gap Two: Your Role, Pay and Even the Company Changed — the Permit Did Not
A work permit names a specific employer and a specific role, so every substantive change inside the company should in principle move that piece of paper, and in practice almost nobody moves it.
What it looks like now: you were promoted, moved teams, changed reporting line, or the company renamed itself or moved its registered address. Work continues, pay continues, and nothing prompts you to update anything.
When it surfaces: at renewal, which is the first moment the four record sets are read together. If the title on the permit, the title in your contract and the role and pay structure in filings disagree, you will be asked to explain; if you cannot, you must remediate; and remediation takes time, which is the one thing renewal never has. Which changes need refiling, which need notification and which need nothing is graded in what a change of role triggers.
The four changes most often treated as trivial:
- Title changed, work unchanged (an internal grading exercise, a global renaming of job families). It looks purely cosmetic, and it is the one most likely to be queried.
- Work changed, title unchanged. Worse, because nothing on paper shows it until someone asks what you actually do.
- Pay structure changed. Shifts between base, allowances and housing affect the consistency of what was declared; see how the salary basis is read.
- The employer itself changed: renaming, relocation, ownership change, merger. You did nothing, yet on paper the employer named on your permit is no longer quite the same entity.
A related gap: work taken on outside the job. A permit ties you to a specific role with a specific employer, and paid work beyond that is a separate question — see whether side work is allowed. The grey area assignees fall into is 'helping out a friend's company as an adviser', which on paper is not a small thing.
Today's check: put the employer name and job title on the permit next to your business card, your email signature and your employment contract. Do all four describe the same thing? Where they do not, tell HR before renewal starts rather than being asked during it.
Gap Three: You Moved, Changed Number, Renewed Your Passport — and Nothing Downstream Was Updated
Your address and document numbers are registered in at least six places that do not sync with each other; miss one and a notice never reaches you, and non-receipt waives nothing.
What it looks like now: you moved from temporary housing to a long lease, changed your number, or renewed your passport. Nothing feels different because you use the new ones daily.
When it surfaces: whenever something must be served on you — a request for supporting documents mid-renewal, a reporting-related notice, a bank compliance query, an insurer trying to reach you about a claim. The signature symptom is that you never learn that anyone tried to contact you, and by the time you find out the matter has moved to its next stage.
Six points on the chain, none optional:
- The address registered on your alien registration card — the address immigration recognises; see what the registration card is.
- The details declared at annual reporting, one of the moments registered information is checked; see the annual report guide.
- Bank and e-wallet address and mobile number, which affect account standing and delivery of verification codes.
- Contact details on the health plan and insurance policies — an unreachable claimant is the most common cause of delay.
- Tax registration and the company payroll system.
- Voluntary registration with your embassy or consulate, and your emergency contact; what consular assistance can and cannot do is in consular protection explained.
Passport renewal is the most underestimated trigger on this chain. A new booklet is not the end of it: the visa and registration details attached to the old one need updating, as do document numbers held by banks, insurers and airline programmes. The renewal process itself is in embassy and consulate document services, but no institution performs the cascade of updates that follows.
Today's check: write the six points on a sheet and confirm each holds the same address and mobile number, and that it is the one you actually use. All six must agree. When you move, update everything in one pass afterwards rather than piecemeal during — piecemeal always leaves one behind.
Gap Four: Long Trips Home, Frequent Travel, and the Space Between Them and the Record
Assignees are usually out of the country far more than they estimate, and that total affects three things at once: the reporting window, tax residency determinations, and stages of processing where leaving is constrained.
What it looks like now: two weeks home for the new year, a month at head office, a few days of regional travel each month, an unplanned trip when something happens at home. Each is short; the sum is a different number entirely. And you have never added it up.
Where it surfaces: three places. First, the trip home early in the year lands on the reporting window — the most common collision, handled in the annual report guide. Second, tax residency turns on days present, and you may be counted as resident in both places or neither; that track is in the money side. Third, leaving while an application is pending, since at some stages your passport is held or you hold only an acknowledgement; see travelling while processing.
The mirror image is just as easy to miss: your stay status breaks and nobody notices. If a permit or visa lapses without your knowledge you can accumulate an overstay entirely unaware, and it is usually discovered on departure. Consequences and remediation are in how overstays are handled, and you can check your own standing proactively — see how to check whether you are restricted. Assignees should note that company-managed filings lapse too: a changed provider, an expired engagement or a list you fell off produce exactly the same outcome.
Today's check, fifteen minutes:
- Go through the stamps in your passport, or your own travel records, and add up days outside the country over the last twelve months. The number usually surprises people.
- Draw next year's known trips home and business travel on the same timeline as the reporting window and your four expiry dates, and look for collisions.
- If you are uncertain about your stay status at all, verify it rather than assuming no news is good news.
One note: your entry and exit record is an official record you can obtain yourself, and it is more accurate than your memory or an HR spreadsheet. When the four record sets disagree, it is often the one that settles the question.
Gaps Five and Six: Cross-Border Contributions Nobody Owns, and the Cost of Being Here Alone
Gap five: social security and tax residency on both sides. The company owns the local side only; the home-country side defaults to you, and most people assume the company has it.
What it looks like now: local salary paid monthly, tax withheld monthly, all very orderly. At home, contributions may still be running or may have stopped years ago; whether you are still treated as tax resident there, and whether foreign income must be declared, has never come up.
When it surfaces: on repatriation, and whenever continuity of home-country contributions is needed — property eligibility, school places, medical reimbursement, pension qualifying years. Returning after three or five years to discover dozens of missing months is the classic case. The annual reconciliation habit is in the annual cycle, the full cross-border logic and the lawful routes in the money side, and the compliance boundary when salary is paid partly from abroad in split payroll and whether it holds up. Local coverage boundaries are in social security for foreign employees.
Today's check: answer three questions. Who is paying my home-country contributions and through which month? Am I still tax resident at home, and is there a declaration obligation on foreign income? Are my local contribution months continuous? If you cannot answer all three, nobody currently owns this.
Gap six: the cost of being here alone, which everyone treats as not a real item — including you.
This is not about feelings; it is about observable signals and available resources. The situation has objective features: your social radius is roughly equal to your employer, colleagues rotate quickly and relationships have a short half-life (the reasons are in the company-centred expat circle); when work goes wrong, housing and immigration status are affected simultaneously, so pressure compounds; distance and time zones mean events at home reach you as news you cannot act on; and daily friction in language and working style consumes patience continuously (see working with local colleagues).
Signals you can assess yourself: a sustained change in sleep pattern over several weeks; loss of interest in things that previously interested you, across the board; avoiding all social contact rather than merely declining events; a marked drop in work output you cannot account for; persistent physical symptoms with an unremarkable check-up. These are not diagnostic criteria — they are a threshold for speaking to a professional once. Chinese-language support resources, online counselling options and when to seek medical care are covered in finding support in your own language.
Three concrete actions that require no courage: fix a regular time to call home (regularity matters more than duration); build at least one social line outside the company (sport, language, any interest); and put two emergency contacts, one local and one at home, on your lock screen and in your wallet. The full escalation chain for emergencies is in the emergency playbook.
This is general information and is not medical, psychological or legal advice; consult a licensed physician or mental health professional on health matters and a licensed lawyer on your own legal situation.
