How to E-file my green card renewal?

[h20mysticshadow]

Why Green card renewal?

USCIS has instructed all the Green card holders to have their cards
with them all the time, irrespective of where they travel or what they
do. Recent laws have authorized the police to pull up anyone that they
feel to be suspicious and check their legal status. In these
circumstances, having a green card (fully valid one) will be highly
useful. Even though the Green cards are issued for the purpose of
granting permanent residency till the entire lifetime of the
individual, they come with a 10 year validity period only. Green card
holders should go in for a green card renewal when the card is about
to expire or has already expired.
