New Jersey DL

How long are they for?

2 years

Got mine January 29th and its good until 2015, but keep in mind its probationary, basic is longer.

Do you tell them that your DACA? Why are they for two years? I don't get how they figure out we're illegal.

One question at a time.
1. You don't have to tell them anything, just show them your 6 points when you walk in.
2. They are two years because that's how long your work permit lasts, my state ID is valid for two years and 3 months.
3. We're not illegal, we have legal presence in the country, and they find out because if you are not a citizen they have a special window you go to and they check your status.
