I am currently in Canada and applied for marriage based greencard. I-130 got approved but due to mistake from USCIS (see I-130 approved (I-797 received): Why do we have to file I-824 (and do we)?) I am forced to file an unnecessary I-824 and wait an additional 7-12 months or even more.
I have an offer for a postdoc position at a prestigeous US university where I would ideally start ASAP.
Is there any way to apply for J1 visa (*) while the greencard is pending?
(*): To my knowledge, J1 and H1B are the only options for postdocs and the latter being tied to a yearly schedule where I could start Oct 2021 at earliest. Please correct if this is wrong.
