H-1B Specialty Occupation (Professionals) Visas
Professional workers with at least a bachelor's degree (or its equivalent work experience) may be eligible for a non-immigrant visa if their employers can demonstrate that they are to be paid at least the prevailing wage for the position.
J-1 and Q-1 Exchange Visitor Visas
Persons coming to the US in an approved exchange program may be eligible for the J-1 Exchange Visitor's visa. J-1 programs often cover students, short-term scholars, business trainees, teachers, professors and research scholars, specialists, international visitors, government visitors, camp counselors and au pairs. In some cases, participation in a J-1 program will be coupled with the requirement that the beneficiary spend at least two years outside of the US before being permitted to switch to a different nonimmigrant visa or to permanent residency.
A Q-1 visa, very similar to a J-1 visa, is a temporary visa for adults (at least 18 years of age) to participate in a training, employment and cultural exchange program. The program must be administered by a US employer and must provide practical training and employment to the participant while facilitating the sharing of history, culture and tradition of the participant’s home country.
I took this from the internet to explain the Q visa since we had mentioned it above.
