I got the point now. Updated the correct question to my father. I will make sure he gets in touch with attorney next week over this.

However, would you please advise on how long it would take for me to get my GC, in your fair estimate? An approximation would do. Also, any political change that might affect my application?

I am born and brought up in India. 30 years of age. Bachelors of Engineering degree with 3 years of work ex in IT. Unmarried yet for GC.
