I had come to US in September 2008 for 30 days externship (as short term visiting scholar) on J1 visa. After that I went back to India in October and came again in January 2009 on F1 visa to do PhD in animal science program. My concern is do I need to apply for J1 waiver before joining a job or a post doc here in USA? If yes, how should I go about it?
The 212(e) can attach to even a short program. Step one, ask DOS for an advisory opinion whether you are subject to the Home Residency Requirement. The detailes are here: http://travel.state.gov/visa/temp/info/info_1288.html
