First of all, the difference between a passport and a visa
Passport is a document to prove citizenship and nationality, while visa is a permit for the holder to enter the destination country. Holding a passport does not mean that you can enter other countries at will, and you need to go through the corresponding visa procedures according to the regulations of the destination country. Different countries have different requirements for visas. Some countries may require detailed personal information and travel plans, while others may require interviews or health certificates.
Second, the validity period and type of passport.
Passport validity is also an important factor affecting entry. Some countries require passports to have at least a certain period of validity at the time of entry, otherwise they may be refused entry. In addition, the type of passport may also affect entry. For example, official passports and diplomatic passports may enjoy special entry treatment in some cases, but ordinary passports need to meet the general entry requirements.
Third, other matters needing attention in international travel
In addition to passports and visas, there are other things to pay attention to in international travel. For example, understand the cultural customs, laws and regulations and security issues of the destination country to ensure personal safety and legitimate rights and interests. In addition, we need to pay attention to the health requirements of international travel, such as vaccination and proof of health status.
To sum up:
Passport is a necessary document for international travel, but it does not guarantee that the holder can go to any country. Each country has its own entry regulations and requirements. Holders need to go through the corresponding visa procedures according to the regulations of the destination country, and pay attention to the validity period and type of passports. In international travel, we need to pay attention to other precautions to ensure personal safety and legitimate rights and interests.
Legal basis:
Passport Law of the People's Republic of China
Article 2 provides that:
The passport of the People's Republic of China is a document issued by People's Republic of China (PRC) to China citizens for international travel. Passport is a passport for citizens to pass through international ports of various countries. Therefore, passport holders are not allowed to enter any country at will, and must obtain an entry permit, that is, a visa, from the country they are going to.
People's Republic of China (PRC) Exit and Entry Administration Law
Article 9 provides that:
China citizens shall apply for passports or other travel documents when leaving or entering the country. China citizens who want to go to other countries or regions also need to obtain visas or other entry permits. However, unless the China government has signed visa exemption agreements with other governments or the Ministry of Public Security and the Ministry of Foreign Affairs provide otherwise. China citizens who leave or enter the country as seafarers and work on foreign ships shall apply for a seaman's certificate according to law.
