What is a J1 and J2 Visa?

The J1 Visa is a nonimmigrant temporary Visa issued for research academics, professors and exchange visitors engaging in programs that facilitate cultural exchange, especially in the United States to receive medical or business training. As for the J2 Visa, this type of Visa is for unmarried children under the age of 21 or the spouse that accompanies the J1 Visa holder during their stay. The J2 Visa holder stays with the J1 Visa holder until they both have to return home after their education program ends.
