What should I do if a foreigner wants to stay in China after his visa expires?

When the visa expires, you must go to the local entry-exit administration department to reapply or extend it, preferably not for too long, otherwise you may be allowed to leave the country within a time limit.

Specific methods:

1. Go to our embassy in China to renew it. At the same time, you should also issue a certificate from the local public security bureau.

2. The second method is more convenient, find a visa company, let them do it for you, pay more money, and don't have to go to the public security bureau in person.

Visa is a kind of license issued by a government agency of a country according to its own laws to foreigners who apply for entry, exit or transit.

According to the principles of international law, any sovereign country has the right to decide whether to allow foreigners to enter or leave the country, and to issue visas, refuse to issue visas or announce the cancellation of visas already issued according to its own laws.

The visa is usually attached to the passport or other international travel documents held by the applicant. Under special circumstances, valid passports or other international travel documents can be written on a separate sheet. With the progress of science and technology, some countries began to issue electronic visas and biological visas, which greatly enhanced the anti-counterfeiting function of visas.

Visas are generally endorsed on passports, some are endorsed on other travel documents instead of passports, and some are issued separately. For example, immigration visas in the United States and Canada are A4 paper, and Singapore also issues separate paper visas to foreigners. Generally speaking, a visa must be used at the same time as a passport to be valid.
