I am at presnt working here on J1 visa. I started on May 1st 2017, and initially I had the DS-2019 for 1 year, but now I come to know that my PI is moving to another city, I cant move with him. So my contract expires on june 30th. My husband is working on j1 visa too and his DS-2019 is of 2 years, my two kids are j2 on his visa. Can I apply for j1 to j2 visa living here in US, if yes then How long does it take to get that?
