What are the main advantages and disadvantages of trying to get J1 vs H1B visas to the USA for a married individual applying for postdoctoral positions (i.e. temporary research position)?
Consider: married to someone from a different country, both need visas to the USA, no clear long-term plan yet on where to settle in the future (though the USA is not particularly attractive in the long term). Staying in academia means no geographic stability and sometimes not ending up in the place where one would most like to.
I'm looking for objective answers to the question above about the differences between these visa types, particularly for scholars (one's status affects the rules that each visa type comes with). The answers do not need to take into account my personal situation. I mentioned it in case something I wouldn't expect to influence a visa does make a difference.
