Visa stay counts from the entry date: an L visa "30-day stay" starts day 1 on entry, and by 24:00 of day 30 you must leave or extend.
Extension: apply 5-7 days before expiry at the exit-entry administration with passport, visa, form and the reason (itinerary proof); usually 3-5 working days with a fee.
Limits: tourist visas usually extend once (30 days); business and family visits by purpose; there is no endless renewal - long stays require the right visa or residence permit.
Overstay: fines run 500 yuan per day (cap 10,000); serious overstays (30+ days) risk shortened stays, re-entry restrictions, even deportation.
Reset by exit: overstayers often leave (Hong Kong, Macau or a neighbour) and re-enter for a fresh stay - but frequent "visa runs" draw border attention.
Math: entry date + stay days - 1; when unsure, call the exit-entry hotline 12367.
In China, how to extend a stay before the visa expires? This article clarifies "extension" and "stay calculation", the two most confusing issues.
First, distinguish two concepts: the visa "validity period" and "duration of stay". Validity is the last date you may enter; duration is how long you may stay after entry.
Example: a visa marked "valid until 30 June 2026, stay 30 days" - you may enter any time before 30 June, but then stay at most 30 days.
A common error: people count 30 days from entry and confuse validity with duration, then overstay. Remember: after entry, count by duration, not validity.
When to extend? If objective reasons (illness, cancelled flights) prevent departure within the stay, apply to the local exit-entry administration to extend.
Timing: generally apply at least seven days before the stay expires; documents include passport, visa, application form and proof of reasons (hospital certificates, cancellation notices).
Limits: tourist visas (L) usually allow one extension, and not for long; the local administration decides.
Extension is not "wish granted": reasons must be real and objective. Subjective "want to play more" is usually refused.
Overstaying is serious: fines of 500 yuan per day (cap 10,000); severe cases mean deportation and a bad record affecting future visits.
So if the stay seems short, the right move is planning ahead for a longer-stay visa (like Q2), not relying on extensions.
A tip for counting: the entry day counts as day one. A 30-day stay with entry on 1 June means leaving by 30 June (most ports count calendar days).
Another easy miss: for multi-entry visas, each entry gets a fresh stay period - still without overstaying.
In short: extension is an emergency stopgap, not a routine. Plan your itinerary well and do not let overstay ruin the trip.
