Here is my situation
Currently I am Engineer in company A.
My company wants to file PERM based on future promotion (title senior engineer)
This job requires 6Yr experience post PhD
Before joining the current company, I have PhD + 3 Yrs 11 months.
Right now I have PhD + 5 Yrs 1 Month (including current company)
My manager is okay with the prevailing wage and if of the opinion that I will be promoted next year (and the current and future job responsibilities are more than 50 % different).
But I am worried that my labor (or may be later I140) will be denied based on the fact that I do not have necessary experience at the time of priority date or labor application.
For PERM based on future employment, when do one needs to show the proof of experience, wages, etc. Is it at 485 stage or I140 stage or labor application date.
