Moving to China with a spouse: Q1 vs S1 and the residence permit timeline

The visa you need is decided by your spouse's status in China, not by the fact that you are married. If your spouse is a Chinese citizen or a Chinese permanent resident living in China, the family-reunion route is the Q1 visa. If your spouse is a foreigner already residing in China on work, study, or similar grounds, your long-term visit falls under S1. Both Q1 and S1 involve a residence permit application after you enter (the service guide treats Q1's reunion class and S1's private-affairs class as separate post-entry residence cases). "Long-term" means more than 180 days (Article 36), and where your visa states a residence permit is required after entry, you must apply within 30 days of arriving (Article 30).

That single distinction — Q1 versus S1 — shapes every later step: the documents you gather, the invitation you receive, and how long your residence can last.

Which visa matches your spouse's situation

Under the 2025 revision of the Regulations on the Administration of the Entry and Exit of Foreigners, Q1 is for foreigners entering for family reunion with a Chinese citizen or a foreigner with permanent residence status in China (Article 6). S1 covers spouses and other long-term visitors of foreigners who reside in China for work, study, or other reasons (Article 6).

The first question to answer is not "Are we married?" but "What is my spouse's immigration footing in China?"

• Spouse is a Chinese citizen or holds Chinese permanent residence, and lives in China → Q1.
• Spouse is a foreign national residing in China on work, study, or other grounds → S1.

The choice is binary and driven by the sponsor's status. There is no intermediate spouse category in this framing.

What the regulations require you to submit

For Q1, the application requires an invitation letter and proof of the family relationship (Article 7). For S1, you submit an invitation letter and either proof of the family relationship or materials related to the private affair (Article 7).

The difference is narrow on paper but consequential: Q1 is built around the family-reunion relationship, while S1 can be supported by private-affairs materials when a relationship certificate alone does not fit the case. The exact document format and the accepting authority are set by the Chinese embassy or consulate where you apply, so confirm the current checklist with that post before you file.

The 30-day residence permit clock

Where your Q1 or S1 visa notes that a residence permit is required after entry, the Exit and Entry Administration Law requires the application to be made within 30 days of entering China (Article 30).

The clock starts the day you land, not the day your belongings arrive or the day you find housing. Plan the in-country appointment before you travel. Missing the 30-day window is a status problem, not a paperwork delay.

What "long-term" means, and how long you can stay

"Long-term" in this context means more than 180 days (Article 36 of the regulations). That threshold is why Q1 and S1 are treated separately from short visit categories.

For the residence itself, the service guide for foreign residence permits distinguishes the Q1 reunion class from the S1 private-affairs class, and notes that for S1 the residence period for the visit can align with the residence period of the person being visited in China. How long your permit ultimately runs depends on the sponsor's own valid status and the materials you present — verify the specific duration against the issuing exit-entry authority, because it is set case by case.

Local and personal variables to expect

The rules above are national. What changes between applicants is the front-end practice at the embassy, consulate, or visa application center handling your file.

The specific receiving post may request additional evidence under the regulations. Confirm its current checklist with that post; do not treat an individual post’s document list as a nationwide S1 requirement.

Personal variables that matter: your spouse's exact status and its proof, where you apply, and whether the relationship certificate is already in a form Chinese authorities accept. None of these change the Q1/S1 split, but they change how smoothly each step goes.

Official rule versus practical suggestion

• Rule: Q1 for reunion with a Chinese citizen or permanent resident; S1 for the spouse of a foreigner residing in China; long-term means over 180 days; a residence permit must be applied for within 30 days of entry where the visa requires it (foreigners’ entry and exit regulations; Exit and Entry Administration Law).
• Suggestion, not a rule: Build your document package early, confirm the checklist with the specific post, and book the in-country residence appointment before you fly. These reduce risk but are not legal requirements and do not change outcomes.
