You need a visa to enter the U.S. and stay in the country on a limited basis. According to The U.S. Department of State, a visa lets you travel to the port of entry, land border crossing or airport and request permission to enter the U.S.
Since possessing a visa does not guarantee your entry into the country, you may have many questions about obtaining and using a visa. Here are some of the most common questions about U.S. visas.
How many types of visas are there?
The type of visa you pursue relates to the purpose of your trip. If you plan to stay in the U.S. on a temporary visa, you can obtain a nonimmigrant visa. If you want to come to the U.S and live here permanently, you will need an immigrant visa. There are also many types of visas that fall under the immigrant visa category.
Can an employer sponsor a visa?
If you are a foreign citizen who wants to come and work in the U.S., you will need a work visa. Your employer can sponsor your visa, but you must first apply for a job and receive an offer from an employer before obtaining this type of visa.
How is a visa different from a green card?
A visa is a pass that lets you come into the U.S. temporarily and remain for a predetermined time period. A green card lets you live in the U.S. and live in the country for as long as you want without expiring.
