My wife who is on H4 got a sponsorship to study in a reputed university. Not sure whether it will be a J or H1B visa. But it could be one among them for sure & it depends on the university. I am on H1B and my wife on H4. My current visa is due for extension on November. My company has filed green card for me a month ago. I think when I do my H1B extension, I should not extend my wife's H4 Visa because it might interfere with her J or H1B visa processing. Correct? What are the other things I should follow? Any help would be appreciated.
