The difference between business visa and work visa

You need to apply for a work visa to work abroad. After this visa expires, the employer can guarantee to renew the employment contract, and then you can renew your identity at the immigration office. Normally, you can't change the visa type halfway. And you can apply for permanent residence or immigration after working in the country for n years.

Business visa mainly refers to the on-the-spot investigation or negotiation of relevant personnel who go to the destination country for investment, trade, conferences, exhibitions and labor services for official or personal reasons. Such people need a business visit visa when they enter the destination country.

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 (such as immigration bureau or its embassy or consulate abroad) to approve the entry of foreign citizens.
