Hi, I m Swiss and on j1 scholar visa in the US. This visa expires end of october. I already have my new DS2019 for a new j1 visa for another 2 years. I have to travel to thailand in december for a conference and want to come back to the US afterwards, which seems obviously difficult because I would have needed to extend the visa beforehand. I heared that I can extend the J1 visa only OUTSIDE of the US. Is that true? How can I apply for an extension before going to Thailand?
