Just a reminder to all of you out there who have green cards — if you are going to be out of the US for more than one year, you need to apply for a Reentry Permit before you leave the US.   You need to be in the US when you apply for the Reentry Permit, and you can’t leave the US until you have had your Biometrics (digital fingerprint and photo) taken.   At that point you can leave and wait for them to issue your Reentry Permit.
