You're right, the application process does have a large variation. However, anecdotal evidence (from my colleagues and me) suggests that if you're not from India or China, you should get it in about 1.5 - 2 years from application.

I've heard some sorry stories for ~ 4 years, but depending on how full the quote lines are I think ~3 years is a good estimate.
