Bringing them with you,
and the paperwork first.

The family half of a move to Shenzhen rarely fails in the way people expect. The visa application itself is short. What goes wrong is the paper trail behind it — a marriage certificate that needed a stamp from an authority in the country that issued it, discovered at a consular counter by a couple who have already given up a flat. Nothing about that can be fixed from here. Someone gets on a plane.

Q or S — it turns on who you are joining

There are two family routes into China and they are not interchangeable. The test is not who you are. It is who you are joining.

• Joining a foreigner who is in China on a work or study status — the ordinary case for a spouse following a Z visa holder — is the S route.
• Joining a Chinese citizen, or a foreigner who holds Chinese permanent residence, is the Q route.

Choosing wrongly is not a correction you make at a counter; it is a different application, filed abroad. The two routes also produce different documents once you are here. Q1 leads to a family-reunion residence permit, S1 to a private-affairs one, and Shenzhen’s service catalogue splits along exactly that line, with separate guides for family reunion ↗ and personal affairs ↗.

Each route then has a long and a short version, divided at 180 days of intended stay. Q1 and S1 are for stays over 180 days and are the ones that convert to a residence permit after arrival. Q2 and S2 are for visits of 180 days or less and never convert — they are stay visas, and you live on the visa itself until it runs out. The Q family definition published by the Ministry of Foreign Affairs is generous — spouses, parents, children, children’s spouses, brothers and sisters, grandparents on both sides, grandchildren and parents-in-law — but a wide definition is not an entitlement. A long-stay Q1 for reunion is still decided on the individual file, and these category notes are revised from time to time, so read the current wording on the China Consular Service Network ↗ before you assume a relationship qualifies.

S1 or S2, and who counts as family

The S1 circle is narrow — spouse, parents, parents-in-law, and children under 18 of the foreigner residing here. That is the whole list. The S2 circle is much wider, adding adult sons and daughters, their spouses, brothers and sisters, grandparents and grandchildren — the same broad list that applies to a short visit to a relative who already holds a residence permit here.

So a mother coming for three weeks at Spring Festival and a mother moving in for two years take different routes, and a brother has exactly one option available to him: S2, a visit.

S2 is one of the categories that can be extended inside China — the extendable list also covers C, F, G, J2, L, M, Q2, R and X2. File at least seven days before the visa expires; the National Immigration Administration guide ↗ gives a decision in no more than seven working days, on a letter from the person being visited, that person’s residence permit, and proof of the relationship. The extendable list and the paperwork behind it are revised periodically, so confirm both against that official page rather than against this one. An extension is not a conversion. An S2 does not become an S1, and I could not find anything on an official page supporting a change of visa category from inside the country. Assume the long-stay application has to be made at a mission abroad, and plan the trip rather than hoping.

One related trap, because it is the cheerful assumption of the moment. China’s unilateral visa-free arrangement — ordinary passport holders of more than forty countries, stays of up to 30 days, announced to run to 31 December 2026 — is a stay, not a residence status. It does not convert to a residence permit, and it does not turn into an S or a Q from inside the country. It is an excellent way to come and look at the city for a fortnight; it is not a way to move here. Both the country list and the end date have been revised more than once, so check what is current on the day you book against the National Immigration Administration ↗ and the visitor entry page.

The certificates that have to be legalised before you fly

This is the section that costs people money. At a Chinese mission the S1 and S2 file is short: an invitation letter from the family member in China, a copy of that person’s passport and residence permit, and the original plus a photocopy of proof of the family relationship — a marriage certificate, a birth certificate, or a kinship certification issued by a public security bureau or notarised. Q applications work the same way against a Chinese ID card or permanent residence card. Treat that as the common pattern rather than a universal checklist: every embassy and consulate publishes its own list and several ask for more, so download the list from the mission that will actually handle your file and work from that.

The proof is where it stops. Documents issued abroad mean nothing to a Chinese authority until they have been validated in the country that issued them. The long-standing route was notarisation followed by authentication at the Chinese embassy or consulate. Since the Apostille Convention entered into force for mainland China on 7 November 2023, documents from contracting states follow the apostille route instead. Either way, foreign-language documents also need a Chinese translation.

Order fresh copies of everything early — many issuing authorities will not legalise a certificate they consider stale, and the round trip through a notary and a foreign ministry runs to weeks, not days. If the application is a Q1 for fosterage rather than ordinary reunion, the bar is higher again: a notarised foster-care entrustment, notarised and authenticated certification of the relationship between the parents or guardians and the child, a letter of consent from the trustee living in China, and a copy of the trustee’s identity document.

Landing in Shenzhen: the first thirty days

An S1 or Q1 visa gets you through the border and no further. The residence permit is the document that actually lets you live here, and it is applied for after entry, in person, in the city where you intend to live.

Validity is not open-ended. Non-work residence permits run from a minimum of 180 days to a maximum of five years, and one to two years is the common outcome. Where inside that range your own permit lands is a decision made at the counter rather than something you can read off in advance, and a private-affairs permit for an S1 dependant is often pegged to the sponsor’s period of residence rather than granted independently — so a spouse’s permit can be shorter than the range suggests. Check what you have actually been given the moment you collect it, and diarise from that date. The residence permit page goes through renewals and changes in detail.

Schools, children, and the eighteenth birthday

A child under 18 rides on the working parent’s status: they enter on S1 and hold a private-affairs permit affiliated to the parent. That affiliation is the thing to understand — a gap in the parent’s permit is the whole family’s gap, not just theirs.

On enrolment, schools set their own admission requirements and I am not going to invent a list. What is consistent across the international schools here is that they want the child’s passport and their valid Chinese status — visa or residence permit — alongside previous school reports and vaccination records, and they want it before a place is confirmed. The sequencing is the genuinely awkward part: the school wants status, the status usually depends on the parent’s work permit, and the academic year waits for neither. Start the school conversation before the visa run rather than after it; the schools section sets out what is available and roughly what it costs.

The eighteenth birthday is a hard edge. Once a child turns 18 they can no longer be affiliated to a parent, and one continuing their education must move onto their own study-type residence permit. Put it in the calendar a year ahead. At the other end of the scale, a baby born here needs a stay or residence registration within 60 days of birth, applied for at the public security exit–entry administration where the parents live, with the birth certificate and both parents’ identity documents.

Can an accompanying spouse work?

The question everyone asks, and the one where I am going to be tiresome.

Not on the dependant status alone — and that is true of S1, S2, Q1 and Q2 alike. A private-affairs or family-reunion residence permit authorises residence for that purpose and nothing else, and a short-stay S2 or Q2 visa carries no right to work at all. Article 41 of the Exit and Entry Administration Law requires a Foreigner’s Work Permit and a work-type residence permit for any work in China, and Shenzhen states the consequence plainly to foreign residents: a fine of up to RMB 20,000 and detention of up to 15 days. That covers informal tutoring and cash arrangements exactly as it covers an office job.

There is one narrow piece of better news, and it has to be read carefully. Shenzhen’s work permit service guide ↗ lists, among those who may lodge a work permit application from inside China, foreign spouses or children of a Chinese citizen, and spouses or children of a foreigner holding permanent residence or a work permit, where they already hold a valid visa or residence permit. That is a door to applying without first flying home. It is not permission to work, it is not a change of status in itself, and it is not a promise that a particular file will be accepted.

Three caveats I am not going to smooth over. The wording turns on the sponsor’s status and does not name S1 holders in those exact words, and I have not been able to confirm from an official page how the Shenzhen counter applies it to a spouse currently on a private-affairs permit. A granted work permit still does not let you start: the residence permit has to be changed to a work-type one, and that has to be in the passport before the first day of work, as set out on the work permit and Z visa page. And this is precisely the kind of rule that is revised and applied differently from counter to counter — treat that service guide as the thing to confirm against, not the thing to rely on, and check it on the day rather than trusting the summary here.

So do not resign a job abroad, and do not accept a start date, on the strength of this page or any other blog. Put the question to the bureau that decides work permits in Shenzhen and to the Exit-Entry Administration that decides the residence permit, and get the answer for your actual status rather than the general case.

Everything above is the published pattern, not a prediction about how your particular file will be read. These rules change, and different missions abroad and different local bureaus apply them differently — the National Immigration Administration ↗, the China Consular Service Network ↗ and the mission handling your application outrank me every time. If you would rather not project-manage the document chain yourself, sequencing certificates, appointments and school deadlines is part of what a relocation day covers, from about ¥1,500, and I come to the appointments with you.
