En relación a tu duda te aclaro:
Las instrucciones de la DV dicen: “You must have either a high school education or its equivalent, defined as successful completion of a 12-year course of elementary and secondary education; OR two years of work experience within the past five years in an occupation requiring at least two years of training or experience to perform. The U.S. Department of Labor’s O*Net OnLine database will be used to determine qualifying work experience. For more information about qualifying work experience, see Frequently Asked Question #13”
En otras palabras : O eres bachiller o debes tener 2 años de experiencia mínima (dentro de los últimos 5 años) en una profesión
