Is it possible to apply for EB1 By getting references from renowned people in the field, but without publications and PhD ?
Without publications close to zero chances. Without PhD many have done it.
No. This will be a straight denial.
What’s your biggest achievement? I knew a friend who gone through eb1 in art performance major. For me I got my eb1 during PhD with citations around 50 in EE when applying and 20+ top-tier conference (<25%)/journal papers.
Can you please elaborate the terms? In EE ; <25%
You can apply, sure. You won't get it approved
What is the solution of the priority date is like May 2018 and got i140 approved for more than 6 months? Just leave the country knowing that green card might never happen?
There aren't any good options. You are in the slow queue - so either be ready for visa shenanigans for pretty much your active career or get a manager role outside the country for a year and come back to file in eb1.
