Every individual visiting the United States should be in the possessing of a USA visa irrespective of his or her purpose of visit and the country that the traveller belongs to.

Based on the different requirements of foreign nationals, the US citizenship and immigration department offers different popular categories of visas. Normally, there are two categories of US visa and they are a non-immigrant visa for a temporary stay in the country and immigrant visa for a permanent stay in the country. The US visa sub-categories are as follows:
B-1 business visa
This type of visa is provided to individuals working in the United States for some foreign company. International citizens looking to visit the country for business purpose are eligible to submit an application for the B-1 business visa. However, their business purpose should not involve obtaining payment or receiving the salary.

H-1B work visa
The H-1B work visa helps college educated individuals with exclusive skills to make an entry into the United States. These professionals can generally be scientists, doctors and engineers. They are individuals visiting the country for making a valuable contribution towards the development of the nation.
