Green Card Renewal
It is done by filing I90 - APPLICATION TO REPLACE PERMANENT RESIDENT CARD online. The instructions are good. The filing can be done in less than 30 minutes. The filing fee is $450.
The receipt notice is sent out immediately upon the filing. Another notice to request an appoinment for biometrics capturing is sent out in 3-4 days. The appointment date is usually 20 days after the filing, and one can request rescheduling.
The biometrics appointment is fairly straightforward - filling a simple form, wait for a few minutes, taking 10-print fingerprints and photo. The entire process takes less than 30 minutes.
It is OK for USCIS if a green card has expired, but it is bad for the holder because he cannot travel abroad and return with an expired green card. USCIS offers a 9-month extension sticker free of charge at the biometrics appointment.
The staff at USCIS, Lawrence, MA are very friendly, knowledgeable and competent.
The new green card is sent out in 4-5 months after filing.
