My question is
Will they withheld my passport and will green card holder face any problem? In immigration.
No, neither the passport can be impounded nor there will be an immigration issue on this, they are just threatening you without knowing the law properly.
What is the best method to escape from this issue?
Whyescape, you can fight it out legally.
Should i fight if so should i stay in india and fight against them?
If you have decided to fight then you may have to either stay in India or give a POA deed to somebody who will represent you during your absence
Or is compromise a best method?
If the tenant is coming for a compromise, then you will be waving your time, money and energy
How it can effect my USA green card ( citizenship ) . I can't stay in india i must go back by selling this paper.
There is no danger to your green card due to this.
Finally if i fight what would be the decision by court?
Depends on how you convince the court based on the documentary evidences, no doubt you are strong but the lapse of time is the drawback on your side.
And how many years it will take?
Cannot be predicted owing to various reasons.
Please mention with acts and IPC. They are filing 420 plus other 3 sec. So please mention what are all the sections my mistakes comes under.
This will not come under criminal offence at all, even then you may decide to fight it out.
