According to international practice, countries (or regions) and airlines inspected by customs generally require that the remaining validity period of the passport held by the applicant be more than 6 months. Even if you have obtained a visa from this country (or region), but the passport is valid for less than 6 months, you will be refused boarding or entry. Passports for adults and children have different validity periods. Ordinary adult passports are valid for 10 years, while 16 children's passports are valid for only 5 years. Therefore, friends must carefully check the validity period of all travelers' passports before traveling with passports. If the passport is not valid enough, it should be renewed at the entry-exit administration department in advance, so as not to affect the normal exit.
