Priority 2 - Eb2 - takes 6-10 years and it is slowing down further with backward movements.
Only Priority 1 - which is high level researcher or renowned scientist/PHD gets it in 2-4 years. They are getting strict on that.
Priority 3 - Eb3 is typical for most Indians. Not decided by employer. Criteria based on what USCIS determined. A Bachelors + 5 years work experience. 10-15 years process, again slowing down will take longer...
Good luck if it is stupid Sacramento USCIS processing your employment green card. The dumb b!atches there admitted that they don't process many employment based Greencards and had to be educated on immigration laws. So if they make mistakes or take wrong decisions - based on you changing employment etc - expect to add a few years in correction. Try to get your green card INTERVIEW in SAN FRANCISCO instead. They are much better.
