Most people who shift to United States temporarily are either students or have a valid H-1B visa. This visa means that the candidates have come to work in United States for a certain period of time. This is known as ‘speciality occupation’. The eligibility criteria for these employees can be different in various categories. But the basic minimum remains the same. They should have a Bachelor’s degree and a job offer in United States. One can only know if a person has fulfilled the criteria of speciality occupation by looking at the different requirements. Mostly a bachelor’s degree is must apart from the professional degree for the speciality field. The degree can be specific to a certain industry. Sometimes the job requirements are such that only a person with highly specialized skills can perform well. The USCIS will look at the education degree or experience in the relevant field which will actually establish his expertise for that highly specialized field.
