Can I exchange my visa J2 to B without leaving the country?

A  J-2 holder can change status in the country so long as he or she is not subject to a two-year foreign residence requirement because of the J visa. The obligation of a J-2  is dependent upon whether the J-1 is subject. If not, you are free to change status to any one for which you are eligible as long as the application is timely and U.S.C.I.S. agrees to make the status change. The fact that you have a tourist visa in your passport has no effect on the adjudication.Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.
