I would like to know how much time from date of injury do i have to get a lawyer?

Generally in NJ it's two years from the date of the injury.  There are exceptions for minors, and other exceptions that an attorney can explain.  Since there is no fee for an initial interview, contact a lawyer right away  There is no reason to wait.   If you are really hurt on the job, then Jose Hernandez in our firm can help you.   856.779.9500.     Also, if claims involve a government entity those claims must be filed within 90 days of the injury.  Be careful.    Good luck.
