based visa
U.S. immigration law provides foreign nationals with a variety of ways to obtain visas and green card through employment in the United States.
U.S. businesses use the H-1B program to employ foreign workers in specialty occupations that require theoretical or technical expertise in specialized fields, such as scientists, engineers, or computer programmers.
The E-3 classification applies only to nationals of Australia. You must be coming to the United States solely to perform services in a specialty occupation. The specialty occupation requires theoretical and practical application of a body of knowledge in professional fields and at least the attainment of a bachelor’s degree, or its equivalent, as a minimum for entry into the occupation in the United States.
The L-1A nonimmigrant classification enables a U.S. employer to transfer an executive or manager from one of its affiliated foreign offices to one of its offices in the United States. This classification also enables a foreign company which does not yet have an affiliated U.S. office to send an executive or manager to the United States with the purpose of establishing one.
You may be eligible to become a permanent resident (obtain a green card) based on an offer of permanent employment in the United States.
