Overview: Coming to the United States
Foreign nationals coming to the United States can be generally classified into 2 classes: Immigrants (or Legal Permanent Residents) and Non-immigrants.
A Non-immigrant is a foreign national who is making a temporary visit to the United States for a specific purpose and for a specified period of time - for business, pleasure, studies, to participate in training or exchange programs, conduct trade or make an investment, work for a specific employer or organization for a specified period, or work for a foreign government or international organization which operates within the U.S. Non-immigrants are required to leave the U.S. when their visas expire, but some non-immigrants may be eligible to adjust to legal permanent resident status.
An Immigrant or Legal Permanent Resident is a foreign national who has been granted legal permanent resident (LPR) or green card status either by way of an approved petition from a qualified family member (family-based immigration), or by a sponsoring employer (employment based immigration), or by lottery under the “permanent diversity program”.
