You hold an out-of-state CDL and move to New York. How long do you have to apply for a New York CDL?
You must apply within 30 days of establishing residency, because a New York CLP or CDL can only be issued to a New York resident.
This answer is not the same in every state
The 30-day window for transferring an out-of-state CDL is set by New York residency rules.
Go by the manual your state publishes — that is what your examiner grades.
