Looks like within 120 days if nothing changes, you will not be able to enter a Federal building or take a flight unless something changes.
Apparently the Driver license from PR and about 9 other states are not going to be acceptable soon unless the states meets the "Real ID" requirements soon.
There is a lot of controversy about this as to when it has to be announced and when it takes effect.
It is unclear exactly what PR needs to do to meet the Real ID requirements, but some of it has also to do with the sharing of information.
FUN!
