Is it good for travel or business to apply for passports and visas in the United States? We received an invitation.

1, going to the United States to apply for passports and visas, tourism and business are inseparable. The review procedure is the same.

2. Passport is a legal document issued by a country to prove the nationality and identity of its citizens when they enter and leave the country and travel or stay abroad. The word Passport means port pass in English. In other words, a passport is a passport for citizens to pass through international ports in various countries. Therefore, some countries in the world usually issue passes instead of passports.

3. Visa refers to the procedure of endorsement and seal of passports or other travel documents held by domestic or foreign citizens by the sovereign organs of a country to show that they are allowed to enter, exit or transit. 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 (such as immigration bureau or its embassy or consulate abroad) to approve the entry of foreign citizens.

4. Tourist visa is a kind of visa, which is generally a quick visa application method for the convenience of tourists and the development of tourism resources. Correspondingly, it is also greatly restricted. Generally speaking, the validity period and stay period are relatively short and can only be used for tourism-related activities. Tourist visa is a kind of visa, and some countries issue tourist visas specifically for tourists, that is, "tourist visas". Tourist visas are characterized by a short stay, usually 30 days, up to 90 days, and generally cannot be extended. Tourist visa holders are not allowed to work in the local area or engage in activities unrelated to tourism. Group tourist visa is a kind of tourist visa, which is characterized in that the visa is not on the passport, and tourists must leave and enter the country with the group.

5. Business visa mainly refers to the on-the-spot investigation or negotiation of relevant personnel who go to the destination country for investment, trade, meetings, exhibitions and labor services for official or personal reasons. Such people need a business visit visa when they enter the destination country. Although the invitation letter is not a necessary document required by law. If there is no invitation letter, as long as the parties can give enough reasons, they can get a visa. In the process of examining and approving business visas, visa officers attach great importance to the authenticity of the invitation letter, including: whether the contents of the invitation letter for business visas are true, whether the inviting unit has legal business activities, and whether there is a ready-made or developing or developed business relationship between the inviting unit and the invitee.
