Consular Processing Procedures
For any would-be immigrant coming to the U.S. from another country, the normal way to apply for and obtain U.S. lawful permanent residence (a "green card") is through a procedure called consular processing. Its key feature is that, after some communication with U.S. Citizenship and Immigration Services in the U.S. (USCIS), the immigrant will deal primarily with, and attend a visa interview at, a U.S. embassy or consulate, likely in his or her home country.
