USCIS does not believe that a J-2 dependent of a J-1 foreign medical graduate can change to H-1B status, or any other employment-authorized nonimmigrant classification (with the exception of T or U status) until the principal Conrad State 30 waiver recipient has fulfilled his or her three-year employment obligations in a medically underserved area.However, USCIS is open to reviewing current regulations and considereing whether steps should be taken to enable such J-2 dependents to engage in employment while in H-4 status.
What kind of visa can I get for medical treatment. I have an appointment with a Surgeon in Anderson. Can the visa be extended without leaving America?
Typically, medical treatment in the USA is undertaken on a B-1 ("Business" visa. Strange, huh?). But do not get confused. Consulates often mark visas as B-1/B-2 or even B-2 (visitors/tourist) for medical treatment. Once here, you can ask for extensions of stay if the circumstances so require. I remember extending the stay of a child and his parents for two years (in 6-monthly chunks), where the baby was being treated for ongoing medical problems.
