Will it be blocked to buy air tickets abroad after the visa period?

1, when the visa expires, you will not be blocked when you return to China to buy a ticket, because when you return to China, airlines only look at whether the passport is valid, not the visa. See a visa only when you go to the visa country or a third country.

2. When going through the customs, you will be fined according to the regulations because the stay period allowed by the visa has expired. The amount is not too big, usually 100 yuan per day. When you arrive in China, you can't see whether your visa has expired, and there are no obstacles.

3. As long as the stay time is not particularly long (usually within three days), it will not affect the subsequent application for going abroad and visa.
