Fingerpring for Re-entry

[immihelp]

I wanted to know if you need finger prints for Re Entry permit to stay out of US for more than year?

What are the fees to apply for Re Entry permit and what documents do we send?

Does the person have to be in US for finger prints or grated re entry permit?

Without re entry permit, how long can green card holder stay out of US?
