Lahurekanchha, As far as I know generally I140 is 2-4 months and I485 is about 3-6 months, but both can be filed together. I824 is generally approved in about 2-3 months. But what is the time after that? I have heard conflicting stories from a year to several years. Might depend upon country too. Any one here done or familiar with cases? Thanks.

Here I824 is for following to join processing.
