What is a visa?

Visa is the annotation and seal of the sovereign organ of a country on the passport or other travel documents held by its own or foreign citizens to show that they are allowed to enter or leave its own territory or pass through it. It can also be said that it is an endorsement certificate issued to them.

Generally speaking, a visa is a document issued by a country's entry-exit administration department (such as immigration bureau or its embassy or consulate abroad) to express approval to foreign citizens. 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. Visa plays an important role in checking and controlling entry-exit personnel, protecting national security and preventing illegal immigrants and criminals.

Matters needing attention in visa application:

1. You should choose a legally qualified travel agency to handle it. That is, a travel agency should have a travel agency business license with outbound business qualification issued by the National Tourism Administration, or an ordinary travel agency business license and business license issued by the provincial tourism bureau.

2. When applying for a visa in a physical travel agency, you should read carefully and sign an agency contract, and the agreed matters should be as comprehensive as possible, such as whether to keep the translated materials.

You shouldn't apply the visa experience of the past or other countries to apply for a new visa. Usually, visa policies will change every six months or so, and visa policies in different countries are different. Some people move their relatives and friends to apply for visas, thinking that everything is easy to handle, and the result is often rejected.

4. It is best not to apply again immediately after refusing the visa. Re-signing immediately after refusal, the success rate is low. Visa officers trust their colleagues' judgment, and refusing a visa means that they have an immigration tendency.

People who have a record of refusing visas, even if the materials submitted are perfect and exceed the level of most people, are still easy to refuse visas again. It would be much better if the interval between visas was long enough. There have been three refusal records, which will have a disastrous impact on any visa in the future, that is to say, the applicant's refusal record should not exceed three times in principle.
