This is the standard visa issued to applicants who would like to live and work legally in the US. However, eligibility is limited to persons with academic degrees or professional qualifications. Under normal circumstances, individuals with only vocational or technical skills cannot be granted this type of visa for admission into the US. The chances of securing this type of visa are better if you have proof of employment or a job offer. The first step should be taken by the potential US employer who must first pay a fee of $600 (US) to file the request for visa, on your behalf, with the US Department of Labor. As soon as this first step is completed, you will be ready to apply directly to the US consulate for your work permit. The work permit visas are issued under very stringent regulations and are valid for a maximum of six (6) years only. Fortunately, conversion to a permanent resident (Green Card) status is possible if you meet a number of employment requirements.
