I have two postdoctoral job offers (both under the J-1 category, different sponsors). My questions are:
If I apply for J-1 with the DS-160 issued by one of the sponsors, if my visa is eventually granted, can I eventually refuse this job offer and work for my other sponsor, even if I applied with the first sponsor? Or should I restart the process again with the DS-160 issued by the second sponsor? If so, what is the cancel procedure, etc? Both jobs are of the same nature, I obviously don't mean changing to a job/sponsor which is not covered by the J-1 program.
In an extreme case, can I work for the two employers? (J-1 sponsored by one of them only, obviously) I am asking this question from the visa perspective, not considering possible work hours incompatibilities, etc.
