Classifying the effort as 'little' for any EB based green card is nuts. Especially for an Indian citizen. In order to apply for EB-2 or EB-3 you need to first do a prevailing wage determination (about 2 weeks). Then your employer has to recruit for the position they want to offer you (30 days posted + 30 days quiet period). After this your employer gets to apply for a PERM (this is currently taking 8-9 months to be adjudicated by the DOL). If you're unlucky enough to be audited in your application you can tack another year on to this step.
After your PERM is approved, you get to file for I-140, which takes another 4-6 months. Then you get to wait until your priority date becomes current which depends on your category and country of origin. This could be anywhere from immediate to 10+ years.
Once your PD is current, you get to apply for I-485 which takes anywhere from 2-6 months and includes doctors exams, finger printing and possible interviews by USCIS. Of course while they're processing this there is no guarantee they wont retrogress your priority date and put you back into the waiting game.
Of course all of this starts again if you change employers (but you do get to keep your priority date if you had an approved I-140).
