Okay, I know this is a very niche question but is there anyone here doing/did a J-find visa to go to Japan to find jobs/postdoc positions (in biotech, specially microbial/mammalian engineering) with no Japanese skill?
With the shit going on in the USA and finding no PhD level works, I plan to get a J-find visa (next year would be my last chance to get the visa due to its 5 years since graduation rule), going to language school while hoping to find a lab to volunteer in (with J-find, I believe I'm allowed to work in university while studying in language schools). But I just want to hear from people who are able to find jobs/postdoc while on J-find. I feel like there are not a lot of opportunities and I will probably never find anything by the end of the visa duration. Thoughts? Guidance?
