There are many types of immigrant visas and each one has different eligibility requirements.
If approved, the application will be forwarded to the nearest U.S. consulate for processing.
The applicant will be notified when a visa number becomes available at which point they will be schedule d for a visa interview.
The interview will take place at a U.S. consulate or embassy. A consular officer will determine whether or not the immigrant visa will be issued. The officer will ask questions about the visa application, the applicant's personal history and their reasons for wanting to live in the U.S.
If the interview goes well, the consular officer will issue an immigrant visa which allows the applica\ t to enter the U.S. The visa will come in a "visa packet" that must be opened only by the Customs and Border Protection officer at the U.S. Port of Entry. Upon entering the U.S., the applicant will receive a visa stamp in their passport and become a lawful permanent resident.
After entering the U.S., a green card will be mailed to the applicant.
