>20 - 30 year estimated wait.

From the Congressional research service's report on immigration backlog [1], for applicants from India, the projected backlogs for various employment-based green card applications applying in 2020 are:

EB-1: 8 years.

EB-2: 195 years.

EB-3: 27 years.

Projecting out to 2030, the report says (for Indian applicants):

EB-1: 18 years.

EB-2: 436 years.

EB-3: 48 years.

"20-30 years" has been wishful thinking for Indian applicants for a long time now.

EDIT: I was bored, so I performed a linear extrapolation using the 2020 and 2030 estimates. Two points and a straight line through them gives:

         eb-1 eb-2 eb-3
    2024 12   292  36
    2023 11   268  34
    2022 10   244  32
    2021 9    220  30
    2020 8    195  27
    2019 7    171  25
    2018 6    147  23
    2017 5    123  21
    2016 4    99   19
    2015 3    75   17
    2014 2    51   15
    2013 1    27   13

All numbers in years. The numbers are rounded up to the next highest integer. Note that a straight line through these two points isn't necessarily the correct model but whatever.
