Nonimmigrant vs immigrant visas
Nonimmigrant visas are for a limited stay. Immigrant visas lead to a green card. Immigrant visas have waiting lines, which you can follow in the monthly Visa Bulletin. This site's issuance numbers cover nonimmigrant visas.
A visa is not the same as admission
A visa lets you travel to a U.S. port of entry and ask to enter. The officer at the border decides whether to admit you and for how long. This guide is general information, not legal advice.
