The REAL ID Act was passed in 2005 in response to 9/11
You will need a REAL ID CARD to board domestic flights, enter military bases or most government facilities.
What is required to obtain your REAL ID is as follows:
CERTIFIED US BIRTH CERTIFICATE The original won't do
VALID US PASSPORT
EMPLOYMENT AUTHORIZATION DOCUMENT
PERMANENT RESIDENT CARD if you are not an American citizen
FOREIGN PASSPORT WITH AN APPROVED 1-94 FORM
In California you must also show a residence document that includes your address. A utility bill for example
You need a PHOTO ID
You need your valid Social Security card and/or a paystub showing your social security number
Don't know what the costs are. Do know it will take time and preparation.
If you don't get a REAL ID card because you don't travel or go to military bases or government buildings you can still get an ordinary Driver's License but it will state you are not REAL. Or whatever.
So now ya know. How many of you plan to comply?
