What is the entry-exit inspection seal?

In many countries, the Immigration Bureau is in charge of border inspection, and in China, the border inspection station is in charge. Entry-exit passengers must fill in the Entry-Exit Registration Card and submit their passports and visas. After the border guards check, they stamp the passport with the inspection stamp of the city and date of entry and exit, leave the entry and exit card and return it to the passenger himself. Countries such as Britain and Japan should check invitations and work permits from time to time. Some countries exempt short-term (within 24 hours) transit passengers from transit visas, allowing passengers to leave their passports at border posts, get transit cards, visit cities, and exchange their passports with transit cards when returning. Some countries require passengers to complete a transit visa at the place of departure, otherwise they may be fined and sent back to their place of origin. Some countries also stipulate that foreign tourists must hold an exit visa from the host country when leaving the country. Many countries require outbound passengers to check their passports after paying taxes at the airport. Passengers should carefully check the check-in lane when they get their passports that have passed the check-in at the border station to prevent mistakes.

Did not leave the country from the designated port. Even if the exit permit and entry permit have been obtained, but they have not entered the country from the port, they should also be considered as illegally crossing the country (border). Anyone who does not pass through the port is not allowed to pass the border inspection. It often lacks two elements at the same time. The performance is that the passport is not stamped with the inspection stamp.
