美国：What does my US employer need to do for E-3?

A US-based employer that wants to sponsor you for an E-3 visa must obtain a Labor Condition Application (LCA) from the US Department of Labor. The potential employer must also provide you with a job letter that establishes that you will be engaged in qualifying work in a “specialty occupation” and will be paid the actual or prevailing wage for that specialty occupation. Unlike most other temporary employment visas your United States-based employer is not required to submit a petition to the Department of Homeland Security as a prerequisite for visa issuance. However, your employer must obtain a Labor Condition Application (LCA), ETA Form 9035, from the Department of Labor.
