Mohan or any knowledgeable person

Is it hard to reinstate a petition because the petitioner died?
What is difference between humanitarian reconsideration and extreme hardship according to INS.Are they the same for INS?
Has anyone ever got their application reinstated?

???

Both are two different subjects.Extreme hardship is only limited to the USC Dependents/spouse where ever the humanitarian bases can be granted to the alien/refugee/others
